ARC/INFOĀ® 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 */
