Today: 1. 2. 3. 4. 5. 6. 7. 8. 9. History of GIS and review of software Data Collection Concept of Projection Using ArcMap (in detail) Georeferencing (BIRN sample) Using ArcCatalog (create shape file, create coverage, projection) Using 3D Analyst & Spatial Analyst (create slope map, contour map) Using ArcReader (sample) Using ArcScene (sample)

History of GIS
Decade 1980’s Milestones for computer-based GIS - ESRI launches ARC/INFO (vector GIS) - GPS became operational - US Army Corp of Engineers develop GRASS (raster GIS) - MapInfo founded - First SPOT satellite launched (Europe) - IDRISI Project started (GIS program) - SPANS GIS produced - National Center for Geographic Information and Analysis (NCGIA) established in USA - TIGER digital data
History of GIS
Decade 1960’s Milestones for computer-based GIS - Canada Geographic Information System (CGIS) developed: national land inventory pioneered many aspects of GIS - Harvard Lab for Computer Graphics and Spatial Analysis: pioneered software for spatial data handling - US Bureau of Census developed DIME data format - ESRI founded - CGIS fully operational (and still operational today) - First Landsat satellite launched (USA) - CARIS founded - USGS begins Geographical Information Retrieval and Analysis System (GIRAS) to manage and analyze large land resources databases and Digital Line Graph (DLG) data format - ERDAS founded - ODYSSEY GIS launched (first vector GIS)
Tomorrow: 1. 2. 3. 4. 5. 6. Geodatabase (Personal Geodatabase , ArcSDE) Geoprocessing ArcMap, ArcINFO (Create hillshade) ArcObjects programming model and demo ArcToolbox (conversions, projections) Anatomy of ArcIMS and internet mapping ,services MetaData Explorer

GIS Software
• The geoprocessing engines of GIS • Major functions
– Collect, store, mange, query, analyze and present
• Key terms
– Program – collections of instructions to manipulate data – Package – integrated collection of programs – Component – self-contained, reusable software building blocks
