GDAL
The Geospatial Data Abstraction Library is a computer software library for reading and writing raster and vector geospatial data formats, and is released under the permissive X/MIT style free software license by the Open Source Geospatial Foundation. As a library, it presents a single abstract data model to the calling application for all supported formats. It may also be built with a variety of useful command line interface utilities for data translation and processing. Projections and transformations are supported by the PROJ library.
The related OGR library, which is part of the GDAL source tree, provides a similar ability for simple features vector graphics data.
GDAL was developed mainly by Frank Warmerdam until the release of version 1.3.2, when maintenance was officially transferred to the GDAL/OGR Project Management Committee under the Open Source Geospatial Foundation.
GDAL/OGR is considered a major free software project for its "extensive capabilities of data exchange" and also in the commercial GIS community due to its widespread use and comprehensive set of functionalities.
Software using GDAL/OGR
Several software programs use the GDAL/OGR libraries to allow them to read and write multiple GIS formats. Such programs include:- ArcGIS – Uses GDAL for custom raster formats
- Avenza MAPublisher - GIS and mapping tools for Adobe Illustrator. Uses GDAL for coordinate system transformation, format reading & writing, geometry operations, & unit conversion.
- Avenza Geographic Imager - Spatial imaging tools for Adobe Photoshop. Uses GDAL for coordinate system transformation, format reading & writing, & unit conversion.
- Avenza Maps - iOS & Android mobile mapping application. Uses GDAL to read metadata information for geospatial maps / data to transform them to WGS84 for offline navigation.
