arctoolbox工具简介

arctoolbox工具简介工具用以对GIS 数据执行小的基本操作。

工具共分为四种类型，如下表所示。

不管工具属于哪种类型，它们的工作方式都相同；可以打开它们的对话框，可以在模型构建器中使用它们，还可以在软件程序中调用它们。

工具类型描述内置工具。

这些工具是使用ArcObjects 和像.NET 这样的编译型编程语言构建的。

模型工具。

这些工具是使用模型构建器创建的。

脚本工具。

这些工具是使用脚本工具向导创建的，它们可在磁盘上运行脚本文件，例如Python 文件(.py)、AML 文件(.aml) 或可执行文件（.exe 或.bat）。

特殊工具。

比较少见，由系统开发人员构建的，它们有自己独特的用户界面供用户使用此工具。

ArcGIS Data Interoperability 扩展模块中具有特殊的工具。

3D Analyst 工具箱提供可在表面模型和三维矢量数据上实现各种分析、数据管理和数据转换操作的地理处理工具的集合。

工具箱以适当方式组织到工具集中，可定义其中的工具所完成任务的范围。

通过 3D Analyst 工具可创建和分析以栅格、terrain、不规则三角网 (TIN) 和 LAS 数据集格式表示的表面数据。

可将多种格式转换为 3D 数据，包括 COLLADA、激光雷达、SketchUp、OpenFlight 和许多其他数据类型。

几何关系和要素属性分析、栅格和各种不规则三角网 (TIN) 模型插值和表面属性分析只是 3D Analyst 工具提供的众多功能的一部分。

The 3D Analyst toolbox provides a collection of geoprocessing tools that enable a wide variety of analytical, data management, and data conversion operations on surface models and three-dimensional vector data. The toolbox is conveniently organized into toolsets which define the scope of tasks accomplished by the tools therein.3D Analyst tools provide the ability to create and analyze surface data represented in raster, terrain, triangulated irregular network (TIN), and LAS dataset formats. 3D data can be converted from a rich variety of formats, including COLLADA, lidar, SketchUp, OpenFlight, and many other data types. Analysis of geometric relationships and feature properties, interpolation of raster and various triangulated irregular network (TIN) models, and analysis of surface propertiessurface properties, such as contours, slope, aspect, hillshade, anddifference calculation.表面三角化提供可确定 TIN、terrain 和 LAS 数据集的表面属性（如等值线、坡度、坡向、山体阴影、差异计算、体积计算和异常值检测）的分析工具。

Triangulated Surface Provides analysis tools that enable the determination of surface properties of TIN, terrain, and LAS datasets, such as contours, slope, aspect, hillshade, difference calculation, volumetric computations, and outlier detection.可见性允许使用不同类型的观察点要素、障碍源（包括表面和适合于表示建筑等结构的多面体）和 3D 要素执行可见性分析的要素工具。

Visibility Features tools that enable visibility analysis to be performed using various types of observer features and obstruction sources that include surfaces, multipatches, which are great for representing structures like buildings, and 3D features.“3D 要素”工具集提供了一组评估几何属性和三维要素间的关系的工具：The 3D Features toolset provides a collection of tools for evaluating geometric properties and relationships between three-dimensional features. The following table summarizes the tools工具Tool 描述Description添加Z 信息添加关于具有Z 值的要素类中的要素的高程属性的信息。

Add Z Information Adds information about elevation properties of features in a Z-enabledfeature class.3D 缓冲在点或线要素周围创建3D 缓冲区。

Buffer 3D Creates a 3D buffer around point or line features.3D 差异消除目标要素类中与减要素类中多面体要素的封闭体相重叠的多面体要素部分。

Difference 3D Eliminates portions of multipatch features in a target feature class thatoverlap with enclosed volumes of multipatch features in the subtractionfeature class.封闭多面体在输出要素类中使用输入多面体的要素创建闭合多面体要素。

Enclose Multipatch Creates closed multipatch features in the output feature class using thefeatures of the input multipatch.根据属性实现要素转3D使用从输入要素属性获得的高度值创建3D 要素。

Feature To 3D By Attribute Creates 3D features using height values derived from the attribute of the input features.3D 内部确定来自输入要素类的3D 要素是否包含在闭合的多面体中，并写入用于记录要素（部分或全部在多面体中）的输出表。

Inside 3D Determines if 3D features from an input feature class are contained inside aclosed multipatch, and writes an output table recording the features that arepartially or fully inside the multipatch.3D 相交计算闭合多面体要素的几何相交，以便根据相交体积生成多面体要素，根据相交面生成面要素或根据相交边生成线要素。

Intersect 3D Computes the geometric intersection of closed multipatch features toproduce multipatches from the intersecting volumes, polygons from theintersecting planes, or lines from the intersecting edges.3D 线与多面体相交确定并返回线与多面体要素之间几何交集的数量。

可选择性地将表示交集的点要素和表示在此类点分开的输入线的线要素写入输出要素类中。

Intersect 3D Line With Multipatch Determines and returns the number of geometric intersections between line and multipatch features. Point features representing the intersection and line features representing the input lines divided at such points can optionally be written to output feature classes.是否为闭合评估多面体要素以确定是否每个要素完全封闭空间体积。

Is Closed Evaluates multipatch features to determine whether each featurecompletely encloses a volume of space.3D 邻近计算每个输入要素到一个或多个邻近要素类中的最近要素的三维距离。

Near 3D Calculates the three-dimensional distance from each input feature to thenearest feature that resides in one or more near feature classes.3D 联合基于输入要素类对闭合的重叠多面体要素进行合并。

Union 3D Merges closed, overlapping multipatch features from an input feature class.CityEngine 工具集包含提供Esri CityEngine 的某些功能而无需安装Esri CityEngine的工具。
