is a translator library for raster and vector geospatial data formats
that is released under an <a href="http://trac.osgeo.org/gdal/wiki/FAQGeneral#WhatlicensedoesGDALOGRuse">X/MIT</a> style
<a href="http://www.opensource.org/">
Open Source</a> license by the <a href="http://www.osgeo.org/">Open Source
Geospatial Foundation</a>.  As a library, it presents a
\link gdal_datamodel.html single raster abstract data model\endlink and
\link ogr_arch.html single vector abstract data model\endlink
to the calling application for all supported formats.  It also comes with a variety
of useful command line utilities
for data translation and processing.  The

Traditionally GDAL used to design the raster part of the library, and OGR the
vector part for Simple Features. Starting with GDAL 2.0, both sides have been
more tightly integrated. You can still refer to the <a href="http://gdal.org/1.11/index.html">documentation of GDAL 1.X</a>
if needed.

\section index_maillist Mailing List

A gdal-announce mailing list <a href="http://lists.osgeo.org/mailman/listinfo/gdal-announce/">subscription</a> is a low volume way of keeping track of major
developments with the GDAL/OGR project.

The <a href="mailto:gdal-dev@lists.osgeo.org">gdal-dev@lists.osgeo.org</a>
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 <a href="http://lists.osgeo.org/mailman/listinfo/gdal-dev/">on
the web</a>.  The mailing list is also available in read-only format by NNTP at
<a href="news://news.gmane.org/gmane.comp.gis.gdal.devel">news://news.gmane.org/gmane.comp.gis.gdal.devel</a>.

Archives since 2005 are searchable on <a href="http://osgeo-org.1560.n6.nabble.com/GDAL-Dev-f3742093.html">Nabble</a>.<p>

Some GDAL/OGR users and developers can also often be found in the
<a href="irc://irc.freenode.net/#gdal">\#gdal</a> IRC channel on irc.freenode.net.<p>

\section index_bugs Bug Reporting

GDAL bugs
<a href="https://github.com/OSGeo/gdal/issues/new">can be reported</a>, and
