OSGeo FDO Provider for SDF |
Introduction
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 provides FDO with access to an SDF-based data store.
The FDO Provider for SDF uses Autodesk's spatial database format, which is a file-based personal geodatabase 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:
-
SDF files can be read on different platforms.
-
The SDF file format 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.
