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.
