Image File Formats

There are a wide variety of file formats currently used for storing image data and it would be impracticable for InfoPACK to support them all. Instead InfoPACK has chosen to support the Geospatial Data Abstraction Library (GDAL found at http://www.remotesensing.org/gdal/) which is a translator library for raster geospatial (GIS) data formats. GDAL currently supports roughly 40 format drivers, some of which are listed in Table 3.1.

If your image is in one of the formats supported by GDAL then you should be able to run any of the InfoPACK routines on your data directly. Alternatively, your existing GIS software may be able to export the data into one of the formats supported by GDAL.

If you are still unable to process your data with InfoPACK then there are a variety of methods that may be used to convert the data.
