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 vector abstract data model
to the calling application for all supported formats. It also comes with a variety of useful commandline utilities for data translation and processing. The NEWS
page describes the September 2014 GDAL/OGR 1.11.1 release.
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.

Developer Oriented Documentation
||FOSS4G 2014 is the leading annual
conference for free and open source geospatial software. It will include
presentations related to GDAL/OGR, and some of the GDAL/OGR
development community will be attending. It is the event for those
interested in GDAL/OGR, other FOSS geospatial technologies and the community
around them. The conference will be held in Portland, Oregon, USA this year starting September 8th - 13th.
A gdal-announce mailing list subscription is a low volume way of keeping track of major developments with the GDAL/OGR project.
The firstname.lastname@example.org mailing list can be used for discussion of development and user issues related to GDAL and related technologies. Subscriptions can be done, and archives reviewed on the web. The mailing list is also available in read-only format by NNTP at news://news.gmane.org/gmane.comp.gis.gdal.devel and by HTTP at http://news.gmane.org/gmane.comp.gis.gdal.devel. Archives since 2005 are searchable on Nabble.
Some GDAL/OGR users and developers can also often be found in the gdal IRC channel on irc.freenode.net.
GDAL bugs can be reported, and can be listed using Trac.
