PR - Our all-new "OpenOSX GrassPro" product doesn't just include the latest version of the GRASS GIS software, it delivers the software as a standalone application that requires only a simple drag-and-drop to install. Not only is this the best version of "OpenOSX Grass" ever developed (requiring zero installation if you have already installed Apple's X11), we've added a host of ready-to-use GIS software and utilities to extend the functionality of GRASS, including MapServer for: publishing dynamic, navigable maps with layers over the Internet; Generic Mapping Tools (GMT): a collection of more than 60 tools for manipulation of geo-spatial data.
