ISMcell2grd
NAME
ISMcell2grd - Converts a GRASS raster map layer into an ISM grid file.
(GRASS Raster Data Export Program)
SYNOPSIS
ISMcell2grd
ISMcell2grd help
ISMcell2grd input=name output=name
DESCRIPTION
ISMcell2grd allows a user to create a grid data file for use in
Interactive Surface Modeling (ISM) from an existing GRASS raster map layer.
COMMAND LINE OPTIONS
Parameters:
- input=name 20
- Name of a binary GRASS raster map input file.
- output=name 20
- Name to be assigned to ISM grid data file created.
If the user simply types ISMcell2grd without specifying parameter
values on the command line, the program will prompt the user to enter these.
NOTES
Since the grid file created by ISMcell2grd is placed in the current
directory, the user should run ISMcell2grd from the ISM file directory
or move the new file to the ISM file directory. In order to use the
grid 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.
The user should note that the maximum ISM grid size is 512 x 512, yet
GRASS cell files are often much larger. ISMcell2grd 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.
