[GRASS-user] Is there an example application where GRASS is used to do some kind of real time display?

[Nithi, Nachi K (Karun)]

Dear All,

I am wondering whether any one has used GRASS to do (semi) real time
display GIS maps. The application that I have in mind is to use GRASS
generated vector maps in PNG or PDF format as background to overlay
place markers and some other quantitative values in multiple layers.
This has to be done every 'N' seconds where N is between 1 and 30.
Under lying metrics can be produced by either custom software or
programs written in language such as R.

 

Regards

Subject: Creating temporary vactor map tables in MYSQL.

 

When we create vector maps in grass with MYSQL as background database it
always creates tables that are permanent. I am wondering whether there
is a way to create temporary tables instead. The problem with permanent
tables is that Mysql creates corresponding files on the disk where the
underlying database tables are stored. This in turn leads to disk
fragmentation if we create hundreds of maps a day. Any idea?

 

Thanks,

-Karun
