To work over Access Grid, GRASS_AG must be used with the Access Grid shared application "SharedGRASS".
GRASS_AG can be also used "normally" i.e. not as an Access Grid shared application. The changes to GRASS_AG merely provide additional functionality to to work together with the SharedGRASS shared application.

Installation Instructions and Notes
Before installing SharedGRASS on your system, see the requirements page for GRASS.To build/install on Mac OSX, see Grass_AG on Mac OSX
You can install GRASS_AG from the source code with the usual './configure && make && make install' sequence.
At this stage you can run GRASS_AG from the command line with:
If GRASS is already installed on your system, this new installation won't erase the old one.
Now, to use GRASS_AG over Access Grid, install the downloaded SharedGRASS AG shared application package with the command:
When running over Access Grid, each participant must have exactly the
same coordinate and map data locally, since such data sets
are often too large to be shared easily through Access Grid.
Each participant needs to launch the application and specify the local
path to the data set.
Want to test ?
To make some tests you will need a sample data set. You can download the spearfish (19MB) data set and a set of scripts (4kB) which contain:- a script to test scripting fuctionality of NVIZ. (go to 'Scripting > Play Script' menu in NVIZ and select the file 'nviz_scripting.test' available in the set)
- a script to test the loading fuctionality of NVIZ. (go to 'File > Load State' menu in NVIZ and select the file 'nviz_state.load')
- a sample script to use with the GRASS GUI (to test most common GRASS functionalities). (click on 'Open existing workspace file' button of the GRASS GUI and select the file 'grass_gui_load.dm')
Known Issues
- Unable to run 2 different istances of NVIZ (3D visualization tool for GRASS)
- vect, vol and site panels in NVIZ haven't been tested yet since we don't know how to use them (need testing, those panels may not work properly)
