Mac OS X installers for GRASS GIS.
Downloads: choose 1 to match your system
when updating, for best results drag the existing GRASS application to the Trash before installing the new GRASS.
The installer does NOT check for the frameworks, so make sure they are installed before trying to run GRASS. GRASS is Universal for PPC and Intel Macs, and runs on Leopard and above. A few support programs, used by various GRASS modules, are included in the application. Also included is a GDAL-GRASS plugin (this used to be included in GDAL).
NOTE: Later system version builds will not run properly on earlier systems (ie Snow on Leo), but due to limitations of the automated package generation the installer will still let you install it on earlier systems.
See the readme for startup options.
Included is a build template similar to the GEM system for modules. But it doesn't require the module source to be configured for GEM (I haven't seen any that are yet). It's a bit rough. See the included readme for details.
GRASS can be used with R. You should get the latest R binaries (at least 2.3.0), the mini install is sufficient (no C/Fortran for building packages from source). The R.app Package Installer is a handy GUI front-end to the install tools. Install the R GDAL package from the GDAL framework (instructions are included with it). Install the maptools binary package from the CRAN binary repository. Install the spgrass6 from the CRAN source repository. See the GRASS stats page for instructions on use.
For GRASS to run on Panther or Tiger, download the source and see the included Mac OS X build notes for help on how to compile from source.
