Oasis montaj How-To Guide在Oasis montaj中使用电子表格本使用指南带您了解在电子表格视图显示、编辑和处理Geosoft数据库数据。

电子表格创建或打开数据库后,会看到电子表格。

电子表格视图是Oasis数据库的"窗口",它还让您可以灵活设置工作环境。

所有数据安全地存储在底层数据库(*.GDB)中 —您只需决定要在电子表格中显示哪些数据,保持其它所有数据隐藏在后台查看不到。

电子表格按行、列和测线(在钻孔绘图等其它应用程序中也被称为组)组织。

行和列与标准电子表格作用类似,可以根据需要编辑与删除。

系统还启用数据库中的多个“工作表”。

具体取决于正在使用的数据类型(测线、随机测线或钻孔),工作表有不同名称。

要查看使用的名称类型,查看电子表格左上角的测线标题单元。

例如"L" 表示正使用测线数据。

如果数据未基于测线采集(地球化学数据),您可将所有数据存储在一条单独的测线中。

电子表格一般功能包括:通过电子表格窗口显示来自数据库的数据的功能任何采样间隔的处理完整的编辑和数学处理功能处理所选样本、所选列和所选测线或组电子表格如何显示工程数据电子表格不显示实际数据,而是显示数据视图。

这让您能够使用电子表格中的数据,而在您决定保存数据库之前,不实际作出对数据的更改。

在您保存数据库后,您的更改是永久的。

根据工程类型的不同,电子表格会将数据显示为值或数组。

对于每个测站记录一个值的测量(例如地磁测量)每个数据单元将包含一个单独的值。

对于每个站记录多个读数的测量(例如激发极化或电磁测量)每个数据单元将包含多个值。

Oasis montaj How-To Guide在电子表格中显示数据系统在电子表格窗口中自动显示所有数据。

当系统创建数据库时,其自动创建测线0 (L0:0)。

在数据导入过程中,如果导入的数据不包含测线0,并因此在该测线中没有数据,则会自动删除该测线。

With the e-mergence of new data processing and the improvement in data interpretation techniques, it has an increasingly more domains of application, and its data processing software is emerging, such as the RGIS, and Geosoft, etc. Based on the magnetic data of some areas in Yuhua Mountain, by using the Geosoft's Oasis montaj platform, the paper carries on data access, visualization, processing, mapping and understanding of graphics output. Through the kringing grid, the reduction to magnetic pole and the first derivative of the vertical obtained results map, we gener-ate the 3D map. In the same way, we obtain the final map from RGIS. We compare these two maps to determine the more advantageous software for high-precision magnetic data processing.Keywords:Oasis Montaj;Reduce to Magnetic Pole;First Derivative of the Vertical;3D76基于Oasis montaj 平台的磁法数据处理解释研究1 数据处理及3D 成图1.1克里格网格化对玉华山部分地区实测数据进行正常场校正和日变校正,得到该区域的每个测点的磁异常值,然后将这些点的异常值分别用Oasis motaj 和RGIS 软件进行克里格(Kringing )网格化处理后,分别得到该区域的磁异常等值线图,如图一和图二所示。

This release also contains many new features and enhancements for the Oasis montaj extensions. Full release notes and downloads .∙New Capabilities∙ montaj Extensions∙ montaj plus Extensions New Capabilities∙ Gridding Enhancements∙ 3D Visualisation∙ New Voxel Utilities ∙Language and Help Accessibility ∙ ArcGIS 10 Support Gridding enhancementsIDW griddingCreates a grid from point data using an Inverse Distance Weighting (IDW) algorithm. IDW gridding is primarily used to interpolate geochemistry data.Direct griddingCreates a grid from highly sampled data without using any interpolation. Intended for use with over-sampled datasets such as LIDAR, it provides a quick gridded view ofthe datasets.Sample density griddingCreates a grid based on the density of sample locations, rather than the value recorded at each location. This is useful for determining the spatial distribution of samples in a dataset, making it easy to identify areas which are under-sampled.Anisotropic krigingCreates a grid that is enhanced in a preferred direction using the strike direction and a weighting factor. This allows you to incorporate the dominant geologic strike and define a preferential weighting in the strike direction, enhancing geological trends in your dataset.Multiple channel gridding improvementsNew multiple channel gridding options for displaying and managing grids. You can now specify a destination folder for all the grids you create and display the grids in a single map, in separate windows, or not at all.Automatic grid display optionsAdded a default option to allow all grids to be displayed automatically as shaded grids instead of plain colour grids, saving time for users who prefer to view grids using the shaded display mode.3D VisualizationImproved isosurface namingThe default name for an isosurface layer now includes both the source voxel name and the cut-off value. This more explicit naming convention is more intuitive and shows where the isosurface originated, providing clarity when multiple element isosurfaces are used in the same 3D view.Zoom to extents of visible groupsYou can now toggle the auto-zoom behaviour off or on, providing you with additional control over how and when the viewing extents change in 3D.Improved display of level plansAdded "Level Plan Grids from Voxels" to the 3D menu to make it easier to create level plan grids. New display options provide you with better control over how your grids are displayed.Improved 3D DXF exportUpdated the export of 3D DXF files to incorporate 3D Face objects as well as polyface mesh objects in our DXF exports. Other software packages (including ESRI ArcScene, GEMCOM, Datamine, Maxwell, Micromine) which only support the 3D Face objects are now able to import Geosoft created DXF files.Improved 3D PDF exportUpgraded our 3D PDF exports to take advantage of new compression methods. 3D PDF exports now create dramatically (up to 10 times!) smaller 3D PDF files which are easier to share.3D view orientation buttonsNew buttons in the 3D Viewer enable you to quickly change the viewing angle to a pre-defined view (North, South, East, West, Top and Bottom) or to a user-defined viewing angle, making it easier to view a 3D model from any angle.3D SnapshotsSnapshots of 3D views may now be created, saved and recalled, enabling you to easily store and retrieve specific viewpoints for your 3D models.Visual clipping of all groups in 3D viewYou can now use the 3D view clipping tools to clip all 3D object types, including: drillholes, symbols, grids and surfaces. You now have the ability to select and visually clip multiple 3D objects at one time. This saves time and provides more flexibility when displaying a few or all of the objects in a 3D view.New Voxel UtilitiesWindow a voxelWe have added a tool that enables you to window a voxel based on manually entered values (X,Y,Z) or a polygon file. Voxels can now be easily clipped to new spatial extents, property, or project boundaries.Re-project a voxelWe have added the ability to re-project a voxel to a new coordinate system. This provides flexibility for the use of voxels in different coordinate systems.Merge voxel modelsYou can now merge two overlapping voxels. The data in the overlapping volume is blended using a cosine roll-off function to create a smooth transition. Merging voxels simplifies the number of voxels you need to work with and converts them to a single coordinate system, point distribution, and colour table.Convert Thematic VoxelsA thematic voxel, such as a lithology voxel created from drillhole lithology data, cannow be converted to a numeric voxel, representing rock densities, electric conductivity or seismic velocity. The voxel conversion uses a lookup file to make the one-to-one conversion.Filter a voxelWe have added a 3x3x3 convolution filter capability that can be applied to a voxel in order to smooth a voxel, emphasize areas of rapid intensity changes, or delineate rock unit or contact boundaries. You can easily add additional custom filters.Voxel displaySimplified the workflow for displaying voxels. The default behaviour has changed so that newly created voxels are now displayed directly in the current 3D view. Improved Target Project voxel griddingExpanded the selection of data channels available for voxel gridding to include all tables in a drillhole project. This saves time and eliminates a step when creating 3D grids from a drillhole project.Voxel to grid conversionCreates a set of parallel grids from a voxel, along the X,Y or Z axis, and at the user specified increment. This capability complements the "Grid to Voxel" feature, providing you with the ability to easily convert between grids and voxels.Language and Help AccessibilityNew language interfaceRussian and simplified Chinese language versions of Oasis montaj 7.3 are available. All the interface and online help files have been translated for each language version.Improved Application Help∙Help topics are now organized around workflows associated with the specific Geosoft Data Processing Sequence steps (Prepare, Import, Edit, Process, etc.)and conveniently display topics by information type (Concept, Procedure, and Reference).∙The Help system launches as a browser window in the new and improved WebHelp format, featuring appealing formatting and visuals consistent withour Geosoft branding.∙Breadcrumbs added to the topic to assist in easy navigation and Help topics and specific search queries can now be tagged as Favourites.Updated help topics can now be sent as part of software resource updates, ensuringyou have the latest help content.ArcGIS 10 SupportSupport for ArcGIS 10 file formatsThis release leverages ArcEngine 10, enabling you to manage and share Esri ArcGIS10 file formats including: geodatabase, MXD, and LYR files.DrillholeAdditional subsurface profiles in sectionsIncreased the number of profiles that can be displayed in drillhole section maps. You can now plot up to eight subsurface geologic contacts as profiles on a section map.Improved drillhole label placementDrillhole collar labels are now supported in eight positions around the collar, providing more flexibility with the appearance of your map. Labels can be oriented horizontally on the map or perpendicular to the trace.New scaling options for downhole dataAdded a log scale option to drillhole data bar plots and profiles. Also added the ability to scale based on only the holes in a section, rather than all selected holes. Improves presentation of data values that are naturally log-distributed (such as geochemical data) and provides more flexibility in data scaling.Improved drillhole planning toolsNew interactive drillhole planning tool can be used to draw a proposed hole on a plan or section map, or to calculate the hole collar location based on target location.Drillhole trace coloursAdded an option to colour the drillhole traces based on text values such as drillhole status. This is helpful when you want to make proposed holes in a different colour from completed holes.Drillhole reportNew drillhole report creates an ASCII file summarizing all holes which correspond to a selected attribute such as drillhole status. This means you can create a report of all your planned holes, and include the total length of all holes in the report.GM-SYS ProfileGM-SYS Profile is an extension for Oasis montaj. Oasis montaj version 7.3 includes important advancements that improve access to data and information, and expand 3D subsurface visualisation and analysis capabilities. The 7.3 release also contains many new features and enhancements for the GM-SYS Profile and the other Oasis montaj extensions. The new capabilities for GM-SYS Profile are provided below. Full release notes and downloads.GM-SYS ProfileObservations and calculations at arbitrary (x,y) locationsWith this release we've added support for observations and calculations for points not located on the plane of the model (Y=0). The results are more accurate as the actual observation locations are used and the calculations are no longer approximations from the plane.Plot station locations in Plan ViewWe have improved the plan view to now display the actual location of calculation stations, relative to model boundaries. This is now necessary as the points are not required to be along the profile at Y=0.Support "dummy" observed dataSupport for "dummy" observed data is a new feature available in this release. This eliminates the need to generate “fake” observations in order to calculate a respons e at locations where no observations are available.Convert skewed models to equivalent geometry with stations off-sectionWe calculate a new model coordinate system that is orthogonal to model strike and adjust the apparent station locations to maintain their true positions. All models now have a "normal" coordinate system that maps 1:1 with any other coordinate system.Convert from MDI to SDI applicationTo improve usability, we now allow only one model per GM-SYS Profile instance,instead of multiple models. Opening a new model creates a new instance in a new window. This approach is more intuitive, simplifies cursor tracking between GM-SYS and Oasis montaj and is consistent with other Oasis montaj views: grid, map, and voxel.Obs/Calc stations decoupled from the modelWe have logically isolated the model description (geometry and properties) from the survey data (observations and field parameters). This will make it easier to support multiple surveys per model (e.g. regional magnetic survey and high-res survey locally).Tie background properties and Earth's field info to survey dataWe have improved the way data is organized by keeping the survey-specific information with the survey data. For instance, Earth’s field parameters are stored with the observed magnetic data. Reduction density is stored with the observed gravity data. This makes it easier to support multiple surveys per model and easily import new survey data.Call IGRFPT to calculate Earth's field infoWe've added the ability to calculate the Earth's Field parameters within the application, to give a more natural data experience.Steamline new model creationIn this release we've provided you with more control over the location and orientation of the model being built. Being able to create a model from available topographic and geographic information, instead of tying it to a survey location provides a more natural workflow.Import observed data from databaseTo address the challenge using intermediate text files for transferring data we have added the capability to import survey data directly from a database into a model.Import horizons from a databaseWe have added the ability to import horizon geometry from a database channel. This removes the need for intermediate text files for transfer of horizon data between Oasis montaj and GM-SYS.Support data imports from other coordinate systemsGM-SYS Profile can now import data from any coordinate system that Oasis montajsupports.Export resampled model horizons to XYZUsers can now export all of the “Named” horizons from a model to an XYZ file suitable for import into Oasis montaj. The result is a streamlined process for building GM-SYS 3D models from GM-SYS 2D profiles.Export selected Plan View extents as a polygonWith this release you can now export a polygon that defines an area of interest in a model, based on the Plan View extents. This is a useful tool for masking external data (e.g. wells or depth-to-basement picks) in Oasis montaj. It's a necessary step prior to importing external data directly from databases in an intuitive way.GM-SYS 3D ModellingGM-SYS 3D is an extension for Oasis montaj. Oasis montaj version 7.3 includes important advancements that improve access to data and information, and expand 3Dsubsurface visualisation and analysis capabilities. There are no new features in this release specifically for GM-SYS 3D. The 7.3 release contains new features and enhancements for the GM-SYS Profile and other Oasis montaj extensions. Full release notes and downloads.Release 7.3There are no new features in this release specifically for GM-SYS 3D. The 7.3 release contains new features and enhancements for GM-SYS Profile, MAGMAP and other Oasis montaj extensions. Full release notes and downloadsRelease 7.2 Enhancements for GM-SYS 3D ModellingDraped surface FFT gravity calculationsWe have removed the limitation that required upward-continuation of your data to a constant elevation. GM-SYS 3D will now calculate the gravity response of a model on a draped surface, typically topography. This new capability allows for a more accurate and detailed modelMenu changesTo improve your workflow the GM-SYS 3D menu has been reorganized into two separate menus. GM-SYS 3D: contains model creation and basic model manipulation including open/close/export functionality. GM-SYS 3D Tools: contains the editing, display, and calculation capabilities.Space-domain vertical prism calculation utilities (Gbox and MBox)This new utility allows you to perform forward calculations for simple vertical prisms. This in an implementation of Blakely's GBox (Gravity) and MBox (Magnetic) forward calculations for testing simple theoretical models.SEG-Y ReaderImproved XML ConfigurationSEG-Y Reader now saves the configuration data in Geosoft-standard XML Metadataformat allowing the SEG-Y Reader to automatically recognize the file format and load it. Making it faster and easier to work with SEG-Y files.Induced PolarisationQC channel separationWe have added a second Quality Control (QC) channel. The chargeability and resistivity now each have their own dedicated QC channels. This provides better quality control flexibility, as the chargeability and resistivity manifest noise at different segments of a cycle they require separate QC channels.Improved workflowIP surveys produce many fields, and as a result, when you import the survey data, numerous channels are created and displayed in the Geosoft database (GDB). Displaying all these channels can make the database window look overcrowded With this release We have added customisable channel display on import so you can display only the channels you are interested in.Zonge import updateWe now support the import of the IP_A VG channel for Zonge FLD data.Schlumberger format supportThe Schlumberger data format is now supported in the IP system.Update Variable a spacingWe have corrected a pseudosection positioning error for variable 'a' electrode spacing. Support for 3D IPNow support the import and quality control of 3D Induced Polarisation data. MAGMAP FilteringBandpass Tapered FiltersWe have added the Cosine and the Butterworth band pass filters. The tapered filters reduce the artefacts due to the discontinuity of the straight bandpass filter.Differential Reduction to the PoleAdded the Differential Reduction to the Pole filter. This is helpful for grids of regional scale, which span degrees of latitude and longitude.Notch FilterWe have added a Notch filter that rejects a specific wavenumber band typically usedto attenuate systematic noise that interferes with the geophysical signature of interest.Convert from Pole to any inc/decAdded the reverse of a Reduction to the Pole filter. Given magnetic data as it isrepresented at the magnetic pole, a magnetic grid can be translated to any givenInclination and Declination.DAPStreamlined Data ManagementDAP data management tasks have been significantly updated to streamline many of the tasks involved in verifying and publishing exploration datasets. Datasets are now verified immediately when uploaded, resulting in a very fast publishing experience. Other data administration tasks have been dramatically improved such as setting security permissions and copyright notices to datasets has been streamlined to be faster and easier.DAP administration web applicationThe DAP administrator application and user interface is now accessed via a browser based web portal. Administrators no longer need to install an application, login to the DAP Server, or have access to a computer with a high bandwidth connection. It is significantly easier for DAP administrators to manage multiple servers in differentregions.DAP Catalog SQL server DatabaseThe DAP catalog and metadata are now tightly integrated and managed together in a single SQL server database. This not only facilitates reporting on who accesses what datasets, it is also an important direction for future improvements.Managed Exploration Information RepositoryDAP datasets are stored in a Managed Exploration Information Repository, and dataset management is now accomplished via the web based DAP Administration Portal. The physical location of the exploration datasets are always synchronized with the DAP Catalog. This eliminates the need for the DAP data manager to directly access the data repository or use other tools such as Windows Explorer that can potentially cause the DAP Catalog and the datasets to become out of sync.Simplified ArchitectureWith this release we have simplified the setup and security of the DAP Server. The DAP data manager can now access all settings in one convenient and easy-to-uselocation.Data PackageWith this release we have added the ability for the DAP Data Manager to be able to filter, organize and create a zipped subset of data, including the organizational hierarchy as a file structure. This data can then be removed from the managed data repository and shared with partners or external organizations.Index MapDAP data managers can now create an Index Map shapefile containing bounding box outlines and structured metadata query fields for all or select datasets managed within the DAP server. This provides yet another view of the information managed within a DAP server.ReportsThe DAP data manager can now quickly and easily view and track the data that has been uploaded by dataset type and how users are using the managed datasets.Support for ESRI 10DAP data managers can now publish ArcGIS v10 Layer (.LYR) file and Map Services.Web-based Metadata EditorDAP data Managers can now edit metadata of a dataset in the Managed Exploration Data Repository via the DAP administration web application.Flexible Presentation HierarchyDAP data managers can now organize data using a defined "folder structure" or using metadata fields to create a folder-like hierarchy. The DAP data managers can easily update the presentation hierarchy without having to un-catalog and re-catalog datasets, or re-organize files on the DAP Server data repository, saving time and effort.Simplified Security ModelData access is controlled using a security model based on groups. The DAP data managers can create security groups based on Active Directory groups and users. In this way, Active Directory will be indirectly supported, and other security models can be added in the future。

Geosoft 地球软件 Gravity and Terrain Correction How-To

Geosoft 地球软件 Gravity and Terrain Correction How-To

montaj Gravity and Terrain Correction How-To GuideSetting Up and Importing Gravity and Terrain DataThe Setting Up and Importing Gravity and Terrain Data How-To Guide will guide you through the options of setting theproject information and processing parameters,as well as importing data for a typical gravity survey.The procedures in this guide include:Set Project InformationImport Base Station DataSave Database ChangesImport Location DataImport Survey DataSet Processing Parameters(Optional)Geosoft provides sample data for you to use when working through these How-To Guides.These data files can be found in your"...\Geosoft\resourcefiles\data\gravity"folder.Set Project InformationWhen you begin a new gravity project,you may want to include information about the project with your data and maps.The Project Information dialog enables you to specify information such as:the company,project name,a project description, scientist name,project date,and any additional comments.This information is stored with the project and is used later for mapping.To Set Project Information1.On the Gravity menu,select Project Information.The Project information dialog appears.2.Type the project information in the parameter boxes provided.You can add additional comments to your project by clicking the Comments button.You will be asked toselect a default text editor,if you haven't done so already.3.Click OK when you are finished to save the Project information with your current project.Import DataOnce you have set your project information,you are ready to import your gravity data into a Geosoft database forprocessing.You will need to import three types of data,base station data,survey location data,and instrument survey readings.For the purposes of this guide,we will demonstrateimporting CG5data.Any data you want to import into the montaj Gravity and Terrain Correction system must first be formatted as aCSV file or an Oasis database file (*.gdb).Your base station data and survey location data should be imported as separate CSV files.Base Station DataBelow is the required format (channel header cells)for thebase station data.Be aware that if you import repeat elevations,only the first is usedduring drift corrections.Survey Location DataBelow is the required format (channel header cells)for the survey locationdata (survey stations).CG5Dump DataBelow is an example of the preferred format for CG5.The CG5CSV dump file has columns for GRAV,TIDE,and TERRAIN.The Gravity and Terrain Correction extension imports the "ALT"channel and reads it as “height”.Upon import you should correct the height channel for the true instrument height (base plate height plus a (normally)constant value for the sensor height above the base (0.089m)).The CG5import will make use of the GRAV and TIDE columns.The TIDE column is subtracted from the GRAV reading and imported as the “Reading”column.Alternatively select to import as ETC.The system does not use the TiltX,TiltY,S.D.,Dur,or Rej fields,as these fields are related to the acquisition quality of the data.However,the SD field is imported to the survey database for quality control purposes.The "Station"channel or the "Line"and "Station"channels of the gravity database are used to look-up location information from the location database.The location data will be placed in the appropriate columns of the gravity database.Import Base Station DataThe first set of data to import is the base station data.This involves two steps.First,you must create a new database or open an existing one.Then,import the data from a CSV fileinto the database.If you need to edit the CSV file before importing,select the 'Edit Base Station File'option on the 'Gravity|Basemontaj Gravity and Terrain Correction How-To Guidestations'menu.Your base station data should include the following columns:station number,gravity reading,longitude,latitude and elevation.To Import a Base Station File1.On the Gravity menu,select Base Stations and then select Open/Create Base Station Database.The Open/create a basestation database dialog appears.2.Specify a new Base station database name,or you can usethe default name,“Base_station.”To import data into an existing database,use the Browse button to locate the database file.3.Click OK.A dialog appears which asks you to confirm that you want to createa new database.4.To accept the database name,click the Yes button.TheLoad data?dialog appears.5.This dialog asks if you want to load(import)gravity data from a file or database into the newly created database.Click Yes.The Import/merge base station data dialog appears.montaj Gravity and Terrain Correction How-To Guide6.Browse to select the Base station database file you want to import the data into.7.From the Base station data source dropdown list,select Text data file orGeosoft database.In our example we are going to select,"Text data file"as our Base station data source.8.Click Next.For our example,the Load base station data from text datafile dialog appears. 9.Browse to select the Base file to load.10.Click OK.The data is imported into the database and displayedin a spreadsheet window.The base station gravity reading does not necessarily need to be a measured absolute gravity value,unlessthe intention is to tie the survey to other gravity network data.Import LocationsThe survey location data are used to establish the location of the survey on the earth.The system requires location information in both long/lat and XY coordinate systems for latitude corrections,merging,and mapping procedures.The latitude values are used for the latitude correction and the long/lat values are used for mapping and the XY coordinates are used for merging the gravity survey information.For this reason,the procedure for importing location data has two objectives.The first is to create a database and import a location data file.The second goal is to generate XY coordinates from long/lat coordinates(or long/lat from XY,depending on the original survey projection).To accomplish these objectives,the process requires three separate procedures.The first procedure is to create a database and import a locations data file.The second procedure is to define a starting projection for the database you created in step1.The final procedure is to define a destination projection.Together,steps2and3enable you to generate XY coordinates from long/lat data or long/lat coordinates from XY data.Import Location Data into DatabaseThe first step is to import location data(in*.CSV format)intoa Geosoft database file.To import location data,you will need the location coordinates in a CSV text file.You can create this file using a text editor or a spreadsheet program like Excel.montaj Gravity and Terrain Correction How-To GuideTo Import Location Data into a Database1.On the Gravity menu,select Locations and then select Open/Create Location Database .The Open/create a locationdatabase dialog appears.2.Specifythe Location database name.When creating a new location database,the new database will include "Station","Longitude","Latitude","X","Y"and "Elevation"channels.You will have the option to load existing location data from another database or a text file..3.Click OK .A dialog asks you to confirm that you want to create a newdatabase with this name.4.Click Yes to confirm.The Load data?dialog appears.This dialog asks if you want to load location data froma file or database.5.Click Yes to accept.The Import/mergelocation data dialog appears.montaj Gravity and Terrain Correction How-To Guide6.By default,your new location database name should be displayed,if not,use the Browse button to select theLocation database.7.From the Location data source dropdown list,you can select either,Text data fileorGeosoft database.In our example we are going to select,"Text data file"as our Location data source.8.Click Next.The Load location data from text datafile dialog appears.9.Browse to select the Location file to load.10.Click OK to import the data.The new database is displayed and includes the Station,Elevation,Longitude,Latitude,XandY channels.In our example the Long/Lat coordinate channels contain dummy values because the data are only projected asUTM coordinates.The next procedure(step2)will demonstrate how to create Long/Lat coordinates from XYprojected data.You can also create XY projected data from Long/Lat coordinate data.Define a Coordinate System for XY and Long Lat Location DataIn the previous step we imported the location data into a Geosoft database.The next step is to define the projection for the current X,Y database values and then to define the geographic(long/lat)projection.To Define a Coordinate System for X,Y and Long Lat Location Data1.On the Gravity menu,select Locations and then select X,Y-->Longitude,Latitude.The Convert map(X,Y)to(Longitude,Latitude)dialog appears.2.From the dropdown list,select the Conversion method as"Local coordinate system"or"Projected coordinatesystem".3.Click OK.The Enter existing coordinate channels dialog appears.montaj Gravity and Terrain Correction How-To Guideing the dropdown lists,select the Current channels.5.Then,use the Process dropdown list to select to process"All lines/groups"or"Selected lines/groups".6.Click Next.The Coordinate System dialog is displayed showing all the known projection informationfor the X,Y database. 7.In this dialog,you can specify the Coordinate system(ensure that the Projected(x,y)radio button is selected),aswell as the Projection method,the Datum,the Local datum transform,and the units ofmeasurementfor Length.For more information on the Coordinate System parameters,click the Help button on the Coordinate Systemdialog.8.Click OK.The Create new coordinate channels dialog appears.montaj Gravity and Terrain Correction How-To Guidemontaj Gravity and Terrain Correction How-To Guideing the dropdown lists,select the New X/Longitude channel and the Y/Latitude channel10.Click Next.The Coordinate System dialog is again displayed,showing all the known projection information for theradio button is selected).new coordinate channels for the Long/Lat coordinates(ensure that the Geographic(long,lat) Array11.Make any necessary changes and click OK.12.The latitude and longitude coordinates are calculated and displayed in the Locations database.Save Database ChangesAfter importing data into a database,it is always a good idea to save your changes to avoid having to import the data again if something goes wrong.To Save Database Changes1.On the Database menu,click Save Database Changes(or from the Standard Bar,select the Save DatabaseChanges icon().The Save Changes dialog is displayed.2.Click Yes tosave your changes.You can use the Database|Discard Database Changes menu option(or select the Discard Database Changes icon())to revert your database back to the last saved version.Import Gravity Survey Data FilesOnce you have your base station and location data imported into a database,you are ready to import your gravity survey files.The example procedure below will lead you through importing a gravity instrument dump file from aScintrex CG5gravimeter.If you want to download a CG3file directly from the instrument,select the Download CG3file option from the "Gravity|Import"menu.To Import a Survey File1.On the Gravity menu,select Import and then select Import Gravity Survey.The Import a gravity file into anew database dialog appears.ing the File type dropdown list,selectthe datafile type.In our example we selected the"Scintrex CG5dump"file type.3.Browse to select the Survey data file for import.montaj Gravity and Terrain Correction How-To Guide4.Click the OK button.The Import aCG3/CG5file dialog appears.5.Select Use CG3.CG5ETC from the dropdown list,to import and use the ETC data stored in the dump file as the tidecorrection value.Select Calculate to usethe Drift Correction method.For more information on the ETC data and the Drift Correction method,click the Help button on the Import aCG3/CG5file dialog.7.Click the OK button and theSurvey parameters dialog appears.The Survey parameters dialog includes information about the survey you just imported as well as global settings such as the base station and location databases.The project remembers all of the information in this dialog.If an import file is missing information,the project will use this stored information to fill in the default values.montaj Gravity and Terrain Correction How-To GuideYou can view the Global Project Parameters at any time by selecting the "Processing Parameters"option onthe Gravity menu.8.If your survey data were collected using an instrument that requires a Instrument scale factor for calibration,you can specify this information in the Instrument scale factor box .Note that,the default setting is to leave the box empty,which means that no scale factor is applied.9.If necessary,you can specify the time difference Hours to GMT (+in W)between the time recorded in the surveydatabase and GMT.This is a positive number in the Western Hemisphere. If this field is left blank,no correction is applied.10.The Latitude correction and Free-air correction text boxes enable you to select the gravity formula you want to use forthe latitude and free air corrections.Select a formula from the dropdown lists.11.Click OK .The survey information from the dump file is imported to your newsurvey database file.If your CG5survey file covers the same stations twice (and using the same base stations)but at different timeand days,you need to consider your drift corrections.After importing,you should split your survey database into two surveys to apply the drift correction,since thedrift calculation does not take into account different dates.The linear drift calculation for a base station on day 1may well be different to a linear drift calculated for day 2,and hence it is best practice to split the different survey days into separate survey databases for the drift correction.We do,however,apply Earth tide corrections based on time and date.Understand the Survey DatabaseNow that you have imported survey data into a database and displayed it in a spreadsheet window,you will notice that there are several channels other than your station,date,time,and reading channels.The "Station"channel or the "Line"and "Station"channels of the gravity database are used to look-up location information from the location database.The location data will be placed in the appropriate columns of the gravity database.Both station and line are used to assign the coordinates.You should compile a locations csv to import consisting of Station,Line,Long,Lat (+\-X,Y)The Type channel is only used for merging survey databases into a master database.Only type 1channels are included in the master database.You can exclude specific stations from being merged into the master database by changing their type to 0.Base stations are not imported into the master database.The Height channel is used as the instrument height correction,so it should represent the height above ground from which the measurement is taken.Geosoft imports the Alt channel (from CG5dump file)and reads it as “height”.Some users record base plate height and put this in the column.Upon import the user should correct the height channel for the true instrument height (base plate height plus a (normally)constant value for the sensor height above the base (i.e.0.089m for the CG5plate).If the user reports another unknown parameter into the Alt channel,be aware it willbe imported as “Height”.In consideration of the daily instrument drift,if your survey data was acquired over more than one day,it is best practice to split the different survey days into separate databases,to properly apply the instrument drift correction.Set Processing Parameters (Optional)The Global survey parameters dialog enables you to view and modify the parameters of your gravity project or of an individual gravity survey database.montaj Gravity and Terrain Correction How-To GuideTo Set the Processing Parameters:1.On the Gravity menu,select Processing Parameters .The Globalsurvey parametersdialog appears.If the current database is a "Single Survey Database"(data imported from a single gravity instrument dump file or from a single "day"survey file),you will be presented with the Survey Parameters dialog (seeprevious step),otherwise you will see the Global Survey Parameters dialog.The Survey Parameters dialog includes both survey specific parameters together with "Global"parameters that apply to the entire project.2.The following parameters can be viewed and/or modified on the Global survey parameters dialog;Base stationdatabase,Location database,Latitude correction (equation to use),Free-air correction,Earth density,Water density,Ice density and Survey type (Ground,Shipborne,or Airborne).3.These parameters are linked to the rest of the dialog boxes and will be filled in as you go through the process.Youcan use the Global survey parameters dialog to specify all your files and settings before you start processing.You can also use this dialog as a reference to check what your current settings are.This will save you typing them in later.This information is stored with the project.4.Click OK to save these parameters with the current project.How-To Guide Publication Date:11/06/2015Copyright 2015Geosoft Inc.All rights reserved.montaj Gravity and Terrain Correction How-To Guide。
