General

What is GDAL?

GDAL name is usually used to name one of following:

• project of translation libraries for raster (GDAL) and vector (OGR) data formats, so in this case GDAL = GDAL + OGR.
• translator library for raster geospatial data formats.

What's this OGR Stuff?

The gdal/ogr tree holds source for a vector IO library inspired by ​OpenGIS Simple Features. In theory it is separate from GDAL, but currently they reside in the same source tree and are somewhat entangled. More information can be found at ​http://ogr.maptools.org. It is my plan to properly fold OGR into GDAL properly at some point in the future. Then GDAL will be a raster and vector library.
