= OGR - Vector Data Access Support =

OGR is a library allowing the reading and writing of a variety of vector formats using a geometry model based on the !OpenGIS Simple Features specification. It is integrated into !MapServer as a way of reading a variety of vector formats.

Its use in !MapServer is detailed in the OGR HOWTO:

  http://www.mapserver.org/input/vector/ogr.html

The OGR library is part of the GDAL source tree, and detailed information about OGR can be found at:

OGR is maintained primarily by Frank Warmerdam, but the OGR integration into !MapServer is done by Daniel Morissette.
