FAQ
ACE2 to CG4 Conversion
What are ACE2 files?
ACE2 is a raw binary raster format used to distribute the Altimeter Corrected Elevations (Version 2) global Digital Elevation Model (DEM), developed through a synergistic fusion of the Shuttle Radar Topography Mission (SRTM) dataset and multi-mission Satellite Radar Altimetry. Distributed primarily as 15 by 15 degree geographic tiles, a file of this type contains matrix elevations with spatial resolutions available at 3, 9, and 30 arc-seconds, as well as 5 arc-minutes. The format inherently lacks embedded geospatial metadata, meaning its exact georeferencing and spatial bounds are determined entirely by standard filename conventions referencing the southwestern edge of the southwestern-most pixel. Native compliance allows these files to be seamlessly integrated into specialized environmental, climate, and terrain modeling software.
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.
