GFF -- Sandia National Laboratories GSAT File Format

Driver short name

GFF

Driver built-in by default

This driver is built-in by default

This read-only GDAL driver is designed to provide access to processed data from Sandia National Laboratories' various experimental sensors. The format is essentially an arbitrary length header containing instrument configuration and performance parameters along with a binary matrix of 16- or 32-bit complex or byte real data.

The GFF format was implemented based on the Matlab code provided by Sandia to read the data. The driver supports all types of data (16-bit or 32-bit complex, real bytes) theoretically, however due to a lack of data only 32-bit complex data has been tested.

Sandia provides some sample data at http://www.sandia.gov/radar/complex-data/.

The extension for GFF formats is .gff.

NOTE: Implemented as gff_dataset.cpp.
