is a translator library for raster geospatial data formats that is released under an X/MIT style Open Source license. As a library, it presents a single abstract data model to the calling application for all supported formats. The related OGR library (which lives within the GDAL source tree) provides a similar capability for simple features vector data. The NEWS page describes the October 2005 GDAL 1.3.1 release.

## Mailing List

The gdal-dev@lists.maptools.org mailing list can be used for discussion of development and user issues related to GDAL and related technologies. Subscriptions can be done, and archives reviewed on the web. The mailing list is also available by NNTP at news://news.gmane.org/gmane.comp.gis.gdal.devel and by HTTP at http://news.gmane.org/gmane.comp.gis.gdal.devel.

Some GDAL/OGR users and developers can also often be found in the #gdal IRC channel on irc.freenode.net.

## Bug Reporting

GDAL bugs can be reported, and can be listed using BugZilla.
