ARC/INFO® ASCII Grid files can be opened as scatter sets in SMS. The files are opened through File | Open. To save the data, they must be saved as a scatter point file.


File Format

ncols ncol /* Number of columns in the grid */
nrows nrow /* Number of rows in the grid */
x11corner x /* Lower left x coordinate of grid */
y11corner y /* Lower left y coordinate of grid */
cellsize size /* Grid cell size */
NODATA_value NODATA /* Value of an empty grid cell */
z11 z12 z13 ... z1ncols /* Values of row 1 */
z21 z22 z23 ... z2ncols /* Values of row 2 */

Sample File
