GDAL is a translator library for raster and vector geospatial data formats that is released under an MIT style Open Source License by the Open Source Geospatial Foundation.

GDAL is also distributed by GISInternals and OSGeo4W and through the NuGet and vcpkg package managers. Linux Packages are available for Debian, Alpine, Fedora, and other distributions. Mac OS …

By default, all drivers that have their build requirements satisfied will be built-in in the GDAL core library. The following options are available to select a subset of drivers:

This method is built on the GEOS library, check it for the definition of the geometry operation. If OGR is built without the GEOS library, this method will always fail, issuing a CPLE_NotSupported error.

It allows users to display most GDAL raster and vector supported formats and provides access to most GDAL utilities through its Processing toolbox. You can also consult the list of software using GDAL.

Starting with GDAL 3.0, the axis order mandated by the authority defining a CRS is by default honoured by the OGRCoordinateTransformation class, and always exported in WKT1. Consequently CRS …

Description gdalinfo program lists various information about a GDAL supported raster dataset. The following command line parameters can appear in any order

Transformation from image coordinate space to georeferenced coordinate space: X_geo = GT(0) + X_pixel * GT(1) + Y_line * GT(2) Y_geo = GT(3) + X_pixel * GT(4) + Y_line * GT(5)

There is a set of generic SWIG interface files in the GDAL source tree (subdirectory swig) and a set of language bindings based on those. Currently active ones are:

The GDAL project (primarily Tamas Szekeres) maintains SWIG generated C# bindings for GDAL and OGR. Generally speaking the classes and methods mostly match those of the GDAL and OGR C++ …
