The Geospatial Data Abstraction Library (GDAL/OGR) is a translator library for reading and writing raster and vector geospatial data formats and is released under an Open Source license. This library is a widely-used data access engine for many applications such as MapServer, Quantum GIS, and others.

The data translation tools included with GDAL/OGR can be built with Ingres support. These tools can then convert spatial data into Ingres geospatial databases. To learn how to build the tools with Ingres support, go to the Actian Geospatial community (https://communities.actian.com) and join the Ingres Geospatial mailing list.

For data conversion, the ogr2ogr command line tool is used. Ogr2ogr is an all-purpose converter of dozens of spatial data formats. In the following example we use ogr2ogr to convert from Esri Shapefile format to Ingres geospatial database format, but many other source and destination formats can be used.

Issue the following command:

The output will list Ingres if it is supported.
