FAQ
HF2 to CG4 Conversion
What are HF2 files?
HF2 is a compact format for terrain height maps, which are rectangular grids where every cell holds an elevation. It was designed to replace uncompressed terrain formats such as HFF, TER, and BT, which take up a lot of disk space. Its distinctive feature is that the person saving the file chooses the vertical precision: a landscape for a game or visualization may be saved with coarse steps and a very small file, while surveying work can keep millimeters. The file may also be compressed with gzip, and in this form it is saved with the .hfz or .hf2.gz extension. The format is used in terrain generation and visualization software, where large landscapes have to be stored and exchanged efficiently.
What are CG4 files?
CG4 is a raster format associated with CALS (Continuous Acquisition and Life-Cycle Support) — a program initiated by the US Department of Defense to capture and link military data. CG4 is compatible with a very limited number of digital graphics programs. Files with this extension contain a bitmap that often uses the CCITT4 compression, which is an old fax machine standard used for black-and-white images.
