Detailed Description

A FileFormat for geospatial vector data supported by OGR.

Geospatial vector data cannot be loaded as a regular (OpenOrienteering) Map because it has no scale. However, it typically has a spatial reference, and so it can be imported into an existing map. This is the major reason for implementing the OGR support as a FileFormat.
