FDO Provider for SDF

The Feature Data Objects (FDO) API provides access to data in a data store. A provider is a specific implementation of the FDO API that provides access to data in a particular data store. The FDO Provider for SDF is a standalone file format that supports GIS data.

The FDO Provider for SDF uses Autodesk's spatial database format, which is a file-based personal geo-database that supports multiple features/attributes, spatial indexing, interoperability, file-locking, and high performance for large data sets.

The SDF file format has the following characteristics:

  • The SDF file has its own spatial indexing.
  • SDF files can store geometric and non-geometric data with minimum overhead.
  • Although it does not support concurrency control (locking), the SDF file format is a valid alternative to RDBMS.

The FDO Provider for SDF can run in a multi-platform environment, including Windows and Linux.
