GDAL

Geospatial Data Abstraction Library (GDAL) is a translator library for raster and vector geospatial data formats that is released under an MIT style license by the Open Source Geospatial Foundation.

As a library, GDAL 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.

For information on the newest release of GDAL, see News.

Note

The current version available on SEPAL is : 3.4.3

Available commands

The complete documentation of GDAL commands can be found on the GDAL website.
