GRASS GIS overview
GRASS GIS, commonly referred to as GRASS (Geographic Resources Analysis Support System), is a Geographic Information System (GIS) used for geospatial data management and analysis, image processing, graphics/maps production, spatial modeling, and visualization. GRASS is currently used in academic and commercial settings around the world, as well as by many governmental agencies and environmental consulting companies.
What's new in version 8.5.0
- New grass.tools Python API to call GRASS tools as Python functions, with direct NumPy array and raster pack I/O
- Completely new documentation rewritten in Markdown and rendered with MkDocs
- Parallelization added to r.mapcalc, r.texture, r.horizon (raster mode), and v.surf.rst cross-validation, with the nprocs parameter extended to r.blend, r.grow, r.mapcalc.simple, and i.image.mosaic
- Added JSON output across dozens of tools (g.list, g.region, r.info, r.univar, r.stats, r.report, v.info, v.what, v.db.connect, and many more)
- New r.smooth.edgepreserve tool for edge-preserving raster smoothing
- v.class and d.vect.thematic: "discontinuities" algorithm fixed and reenabled
- Expanded grass.jupyter: query button and drawing of simple geometries in InteractiveMap, interactive computational region updates, parallelization in TimeSeriesMap and SeriesMap, and a save() method for Map3D
- Multiple masks per mapset, driven internally via the GRASS_MASK environment variable, with a new r.mask.status tool for reporting mask state, respected by r.mask
- RegionManager and MaskManager context managers in grass.script for scoped region and mask changes
- GUI improvements: projects can be added directly in the Data Catalog, column statistics can be computed on SQL-filtered or interactively selected rows in the attribute table manager, the Python editor is now dockable, the command history panel supports copying commands, and the Graphical Modeler variable syntax changed from %variable to %{variable}
- Conda package now available as an installation option
- CMake support for building GRASS and addons, alongside the existing Autotools build, including native Windows builds with the MSVC compiler
- Fixed more than 500 security issues reported by Coverity Scan
- Updated requirements: GDAL 3.7+, PROJ 9.0+, C++17, Autoconf 2.72, Python 3.10+, and the CBLAS and LAPACKE C interface for BLAS and LAPACK
- Local macOS builds: A new script to easily build a binary (useful for building for Intel architecture, see #4946)

Version: 6.4.1-5
Before I dive in, how does this run on Lion? Any opinions about whether I need more than 2 or 3 GB of RAM, and will it run reasonably on my late-2006 2.16 GHz iMac? And, though it appears to be an OS X port, I just want to be sure: It’s not Java, is it?

Version: 6.4.1-1
The requirements listed are incomplete. There are several support frameworks that have to be installed before installing GRASS. Go to the developer's web site for the full scoop.
Also, the latest version for 10.5 is available, and it's a universal Intel/PPC binary:

Thanks to the new mirrors - good speeds. And thank you, Lorenzo Moretti, for your hard work and your patience with all the negative comments.
GRASS itself is powerful and this distribution makes installation a snap. Good work!

1st - Give the developer a break. It's free and it is big. He does not host it on a big fast server - so what IT IS FREE. If you think you can do better, contact the developer, I am sure he would be more than willing to mirror his 100's MB of files on your free server.
2nd - Note this is an OSX port of the newer beta version of Grass including a menu driven interface and a GUI. There is an OSX version of the current release of Grass but it only has a command line interface and it will cost you a few $100. The fact that someone is porting the latest and greatest to OSX is GREAT!!!!
3rd - Grass in not for the casual user. It is very powerful but it is not trival. If you haven't used it before, plan on spending days (if not weeks) on coming up to speed.
4th - It requires X11. I am running it under 10.2.8 so I am using the old beta release of X11 (that does not require 10.3). There are some stability problems but it is not clear if this is a Grass issue or the fact that I am not using the most up to date version of X11.
