FAQ
ASC to CG4 Conversion
What are ASC files?
The ASC (Esri ASCII Grid) format stores raster geospatial data as plain text. Developed by the Environmental Systems Research Institute (ESRI), it describes a rectangular grid of cells using a short header — number of columns and rows, coordinates of the lower-left corner, cell size and a no-data value — followed by the cell values themselves, written row by row as ordinary numbers. Because the entire grid is human-readable text, ASC is widely used for exchanging elevation models, slope maps and other continuous surfaces between GIS packages that would otherwise share no common binary format.
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.
