<h2>Geospatial Data Translation Tools<a class="headerlink" href="#geospatial-data-translation-tools" title="Permalink to this headline">¶</a></h2>
<p>Geospatial Data Abstraction Library (GDAL/OGR) provides command-line
utilities to translate and process a wide range of raster and vector
geospatial data formats.</p>
<p>The utilities are based upon a cross platform, C++ library, accessible
via numerous programming languages. As a library, it presents a single
abstract data model to the calling application for all supported formats.</p>
<p>GDAL/OGR is the most widely used geospatial data access library. It provides
the primary data access engine for many applications including MapServer,
GRASS, QGIS, and OpenEV. It is also utilized by packages such as OSSIM,
Cadcorp SIS, FME, Google Earth, VTP, Thuban, ILWIS, MapGuide and ArcGIS.</p>
