OGR: OGR Simple Feature Library The OGR Simple Features Library is a C++ open source library (and commandline tools) providing read (and sometimes write) access to a variety of vector file formats including ESRI Shapefiles, S-57, SDTS, PostGIS, Oracle Spatial, and Mapinfo mid/mif and TAB formats. OGR is a part of the GDAL library. Resources Download Ready to Use Executables The best way to get OGR utilities in ready-to-use form is to download the latest FWTools kit for your platform. Source The source code for this effort is intended to be available as OpenSource using an X Consortium style license. Bug Reporting GDAL/OGR bugs can be reported, and can be listed using Trac. Mailing Lists 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 OGR and related technologies. Alternative Bindings for the OGR API
