[GRASSLIST:1352] Web Mapping

[m.malicky at landesmuseum-linz.ac.at]

Hi!

Currently I am developing a web mapping tool for GRASS mainly 
with PHP for our biodiversity Database.
As I am using the CELL driver for generating pictures I have the 
following questions:

How can I reset the CELL driver ? - changing the vars 
GRASS_WIDTH and GRASS_HEIGHT to another value after using 
the driver gives me error messages.

What does happen if 2 processes try to access the ressource 
D_cell at the same time ?

Do I have to write a scedular to avoid ressource conflicts ?

As each process may re- g.region the GRASS-database, do I have 
to lock this ressource also ?

kind regards

Mike
