The program prompts the user to enter the name of the SUN raster file to be converted and the name to be assigned to the GRASS raster file to contain the resultant image.
It is recommended that this program be used in an x,y database (as opposed to, for example, a UTM data base), since the cell header is created with nonsense coordinates (i.e., coordinates designed only to specify the number of rows and columns in the image). Of course, the user can adjust the cell header after import using r.support .
The user must, of course, first create the SUN raster file to be converted, either by running the SUN "screendump" utility (to capture a displayed image) or by some other means (e.g., from a scanning system that produces SUN raster file format).
