Arc/Info Binary Grid

This project involves researching the Arc/Info Grid Binary format. This format is undocumented by ESRI, and has an varied set of compression possibilities.

In addition to the format description, it is expected that code for reading arc/info grids will be released under an OpenSource license at some point in the near future. I do not plan at this time to write grids.

Format Description
A simple, but buildable distribution of the aitest program using this library is available as aitest_dist.zip.

Support for reading arc/info binary grids is incorporated into the GDAL raster library via the aigrid code, as well as support for reading and writing using the ESRI grid dll where available.
