For each (x,y) position in the original cell file, ISMcell2scat assigns an attribute for the scattered data file. This program is useful when the user wants to take advantage of smoothing capabilities of ISM.
The user should note that the maximum ISM grid size is 512 x 512, yet GRASS cell files are often much larger. ISMcell2scat currently resamples larger cell files at 512 x 512 resolution. To avoid losing information, the user may want to resize the grass cell file prior to exporting the data.
Since the scattered data file created by ISMcell2scat is placed in the current directory, the user should run ISMcell2scat from the ISM file directory or move the new file to the ISM file directory. In order to use the scattered data file, the user must also add it to the ISM table of contents (.toc file) by choosing option 3 (edit/create file) under FILE OPERATIONS.
