Geospatial Data Abstraction Library#
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 latest release.
Note
The current version availalble on SEPAL is : 3.4.3

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