• Download binaries if you want to install ready-to-use GRASS GIS. Binaries need some hundred megabytes of disk space.
  • Download source code if you want to develop your own GRASS extensions or run GRASS on a special computer platform. The source code needs around 350MB+ of disk space.
  • First time users should explore the first steps tutorial after installing.
  • See here for our roadmap - the release schedule.
