GDAL - Geospatial Data Abstraction Library
Select language: [English][Russian][Portuguese][French/Francais]

GDAL is a translator library for raster and vector geospatial data formats that is released under an X/MIT style Open Source license by the Open Source Geospatial Foundation. As a library, it presents a single raster abstract data model and single vector abstract data model 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 NEWS page describes the December 2018 GDAL/OGR 2.4.0 release.

OSGeo project

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 documentation of GDAL 1.X if needed.
