Free grass gis 6.4rc5 software for mac

GRASS GIS 6.4rc5 is stand for Geographic Resources Analysis Support System, which used for data management, image processing, graphics production, spatial modelling, and visualization of many types of data. It is Free (Libre) Software/Open Source released under GNU General Public License (GPL). GRASS is official project of the Open Source Geospatial Foundation.
Originally developed by the U.S. Army Construction Engineering Research Laboratories (USA-CERL, 1982-1995), a branch of the US Army Corp of Engineers, as a tool for land management and environmental planning by the military, GRASS has evolved into a powerful utility with a wide range of applications in many different areas of scientific research. GRASS is currently used in academic and commercial settings around the world, as well as many governmental agencies including NASA, NOAA, USDA, DLR, CSIRO, the National Park Service, the U.S. Census Bureau, USGS, and many environmental consulting companies.
The new GRASS 6 release introduces a new topological 2D/3D vector engine and support for vector network analysis. Attributes are now managed in a SQL-based DBMS. A new display manager has been implemented. The NVIZ visualization tool was enhanced to display 3D vector data and voxel volumes. Messages are partially translated (i18N) with support for FreeType fonts, including multibyte Asian characters. New LOCATIONs can be auto-generated by EPSG code number. GRASS is integrated with GDAL/OGR libraries to support an extensive range of raster and vector formats, including OGC-conformal Simple Features.
The GRASS Development Team has grown into a multi-national team consisting of developers at numerous locations.
In September 2006, the GRASS Project Steering Commitee was formed which is responsible for the overall management of the project. The PSC is especially responsible for granting SVN write access.
Major Features:

1. GRASS (Geographic Resources Analysis Support System) is a raster/vector GIS, image processing system, and graphics production system.
2. GRASS contains over 350 programs and tools to render maps and images on monitor and paper; manipulate raster, vector, and sites data; process multi spectral image data; and create, manage, and store spatial data.
3. GRASS uses both an intuitive windows interface as well as command line syntax for ease of operations.
4. GRASS can interface with commercial printers, plotters, digitizers, and databases to develop new data as well as manage existing data.
   
5. GRASS supports workgroups through its LOCATION/MAPSET concept which can be set up to share data over NFS (Network File System). Keeping LOCATIONs with their underlying MAPSETs on a central server, a team can simultaneously work in the same project database.
   
6. GRASS is released under GNU GPL, the source code (5.x: more than 1 million lines of C; 6.x 500k SLOC) is completely available.
7. GRASS provides a sophisticated GIS library which can be used for own developments.

OpenOSX Grass is a program that will make a "grass" folder in your home directory if it does not exist and will also create a tutorial, "spearfish" dataset in your "grass" folder.
It is recommend that you create your datasets in the "grass" folder (you can always link other directories there by making an "alias" or "symbolic link"), because "OpenOSX Grass" will try to change to that directory by default (this can be customized - however), thereby selecting the database to use for you.
Our all-new "OpenOSX GrassPro" product doesnt 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 Apples X11), weve 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;
- more than a dozen BLM command-line utilities and much more!
- NVIZ support for 3D vector data & voxel volumes.

Requirements:
Color monitor.

MFworks 3.0.1 is a product which is the combination of the most highly demanded elements of grid based spatial analysis into a simple and efficient tool. It provides a powerful suite of analytical and modeling capabilities with a user-friendly interface. MFworks is perfect for new and experienced Geographic Information Systems (GIS) users who are interested in creating their own solutions to spatial analysis problems.

MFworks represents an easy-to-use toolbox for the analysis and visualization of spatial data. This desktop application is an excellent complement to vector based GIS tools. It can also employ unique analysis features as a stand-alone product. The intuitive interface makes it easy to master the system quickly and to creatively explore spatial processing ideas.

MFworks is descended from a long line of popular grid/raster GIS packages like MAP II and Mapï¿1⁄2Factory which were created by Keigan under the name of ThinkSpace Inc.
The grid based family of Keigan products are used by researchers, analysts, engineers, planners and educators interested in the relationships between geographical elements and events.
