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
| ncols | 136 |
