GRASS_AG is a modified version of the famous GRASS 6.0.0 GIS (Geographic
Software), which allows users to run GRASS within an Access Grid
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
application. The changes to GRASS_AG merely provide additional
to to work together with the SharedGRASS shared application.
Installation Instructions and Notes
Before installing SharedGRASS on your system, see the requirements page for
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:
and it will provide exactly the same functionality as the
normal version of GRASS 6.0.0.
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
shared application package with the command:
agpm.py -p SharedGRASS.agpkg
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
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')
This is a test version, thank you for reporting bugs to ...
- Unable to run 2 different istances of NVIZ (3D visualization tool
- 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
