OpenOSX.com, a business dedicated to serving the Mac OS X community, has released its Grass Pre 2 CD, which lets you install Grass (Geographic Resources Analysis Support System) GIS (Geographical Information System) Pre 2 for Mac OS X.
The OpenOSX Pre 2 CD offers Mac OS 10.0.x through 10.1 compatibility (including dual processor support) and additional modules, along with bug fixes. With over 350 modules, Grass is the “only real alternative” to ArcView GIS, Jeshua Lacock, the owner of OpenOSX.com, said.
Grass GIS offers 3D dynamic spatial analysis and visualization. Users of Grass include NASA, USGS (U.S. Geological Survey) and NOAA (National Oceanic and Atmospheric Administration), among others, Lacock said. The OpenOSX CD installs a long list of all the required libraries and programs for full functionality, he added
