Migrating to GRASS

Welcome! There is a lot of help on the web and a wealth of expertise available on the mailing lists and via IRC.

Tips for recent migrants

GIS "The GRASS way"

Interoperability

Collaboration with external software is highly encouraged.

Portability

  • All code POSIX C and generic UNIX compatible
  • Most code MinGW compatible for native MS-Windows

Scriptability

  • GRASS GIS is made up of modular tools specifically designed for easy scriptability in any number of common scripting languages, see GRASS and Shell
  • Interface for direct hooks into higher scripting languages (esp. Python), see GRASS and Python and
  • if "GRASS_BATCH_JOB=/path/to/script.sh" is set GRASS 6+ will run the script as a batch job and exit when it is complete. Start GRASS with the full path to the mapset to avoid the startup menus. See also GRASS and Shell.
