GRASS Help System |
One useful function performed by GRASS is to output data in a form suitable for input to other existing computer models. GRASS programs allow GRASS data to be interfaced with those of the BNOISE (blast noise simulation), ARMSED (watershed and sedimentation modeling), ELAS (image processing), UW-RIM (University of Washington's version of the RIM relational data base management system), the "S" statistical package, and ISM (interactive surface modeling) programs.
These programs are distributed with GRASS, but the user must compile them separately. Compilation instructions are included in the "GRASS 4.0 Installation Guide" distributed with the "GRASS User's Reference Manual".
In some cases (e.g. to compile RIM and the GRASS programs interfacing RIM), the user needs a FORTRAN compiler to compile this software. A FORTRAN compiler is not distributed with GRASS.
The user can use GRASS programs in combination with UNIX functions and other programs to build macros that convert data into a form suitable for import and export to/from programs other than those listed above.
