Importing Autodesk SDF (Spatial Data Files)
Concept Procedure Quick Reference
 
 
 

SDF is a native Autodesk file-based geospatial format that is optimized for storing large, classified data sets.

SDF is similar to SHP format in that it contains both spatial data and attribute data. However, unlike SHP, it stores both types of data in a single file rather than a set of files.

When drawing data is stored as SDF, you can use Autodesk MapGuide Enterprise 2007 to style and publish the data to the Internet. You can also publish map data directly to MapGuide, without exporting to SDF.

Versions

The current version, which works with AutoCAD Map 3D and Autodesk MapGuide Enterprise, is SDF version 3. AutoCAD Map 3D refers to this version as “SDF.”

SDF version 2 is still supported by MapGuide 6.5 (and earlier releases), and AutoCAD Map 3D can import and export SDF 2 using a separate import/export interface.

Advantages

SDF has the following advantages over DWG:

Importing

When importing SDF, you can import each feature class in the SDF to a separate layer. You can specify how you want to bring in attribute data and points. You can also set an option to import polygons as closed polylines.

Driver Options

SDF has no import driver options.
