ADRG -- ADRG/ARC Digitized Raster Graphics (.gen/.thf)
Driver short name
ADRG
Driver built-in by default
This driver is built-in by default
Supported by GDAL for read access.
An ADRG dataset is made of several files. The file recognised by GDAL is the General Information File (.GEN). GDAL will also need the image file (.IMG), where the actual data is.
The Transmission Header File (.THF) can also be used as an input to GDAL. If the THF references more than one image, GDAL will report the images it is composed of as subdatasets. If the THF references just one image, GDAL will open it directly.
Overviews, legends and insets are not used. Polar zones (ARC zone 9 and 18) are not supported (due to the lack of test data).
