ESRI ARC/INFO ASCII Grid (*.asc)

ARC ASCII GRID refers to a specific interchange format developed for ARC/INFO rasters in ASCII format. The format consists of a header that specifies the geographic domain and resolution, followed by the actual grid cell values.

A non-proprietary ASCII format/Raster GIS format. Usually the file extension is .asc, but recent versions of ESRI software also recognize the extension .grd. Coordinates may be in decimal or integer format. DD:MM:SS format for geodetic coordinates is not supported. Used as an exchange, or export format, due to the simple and portable ASCII file structure.
