# AIG -- Arc/Info Binary Grid

Driver short name

AIG

Driver built-in by default

This driver is built-in by default

Supported by GDAL for read access. This format is the internal binary format for Arc/Info Grid, and takes the form of a coverage level directory in an Arc/Info database. To open the coverage select the coverage directory, or an .adf file (such as hdr.adf) from within it. If the directory does not contain file(s) with names like w001001.adf then it is not a grid coverage.

Support includes reading of an affine georeferencing transform, some projections, and a color table (.clr) if available.

This driver is implemented based on a reverse engineering of the format. See the Arc/Info Binary Grid Format for more details.

The projections support (read if a prj.adf file is available) is quite limited. Additional sample prj.adf files may be sent to the maintainer, warmerdam@pobox.com.

NOTE: Implemented as aigdataset.cpp.
