The Geospatial Platform API for AutoCAD Map 3D is used for connecting to and working with data from geospatial feature sources.

Note:

Much of this API is shared with Autodesk MapGuide Enterprise. Some methods are specific to MapGuide and will throw an exception when used in AutoCAD Map 3D. These are noted in the description of the methods.

AutoCAD Map 3D contains some classes and methods that work with the Geospatial Platform API but are specific to this product and are not included in the MapGuide products. See the Geospatial Platform Supplement Reference for details.

For detailed information about using the Geospatial Platform API see the AutoCAD Map 3D Geospatial Platform Developer's Guide.

Maps are made up of layers, where each layer displays features from a feature class. See Maps and Layers for more details.

Much of the work with this API is done through the following services:

• Resource Service: manipulates resources and repositories.
• Feature Service: provides access to FDO providers.

Some other important areas of the API are:

• Coordinate System: supports coordinate system transformations.
• Geometry: manipulates geometric objects.
• Collections: classes to hold collections of objects.
• Common: common utility classes.
• Exceptions

The API uses XML data extensively. The schemas are documented in XML Schemas.
