[GRASS-dev] Batch Processing in GRASS GIS

GRASS GRASS developer
1


Sir,

My project is based on batch processing in GRASS GIS.
I have created new vector (points) from database table containing coordinates. After this, using v.to.rast converts the binary GRASS vector map layer into raster.Then surface interpolation is done using r.surf.idw successfully.The next step is to do batch processing and it is performed using these steps



<br>chmod u+x $HOME/my_grassjob.sh<br>export GRASS_BATCH_JOB=$HOME/my_grassjob.sh<br>grass63 ~/grassdata/spearfish60/neteler/<br>



Problem is concurrent users cannot access it.What to do for concurrent acccess and also where the result of batch processing displays and how we can view it.Also guide me how to set the time intervals in batch processing.
Please reply me as soon as possible.

Thank you

Regards

You need to use temporary mapset names (e.g., using the process
ID which is stored in the $$ variable).

What to do for concurrent
acccess and also where the result of batch processing displays and how we
can view it.Also guide me how to set the time intervals in batch processing.

Then you need to copy the results to a target mapset. See
http://grass.osgeo.org/wiki/Parallel_GRASS_jobs
for details.
