hi all,<br>
I wish to develop a situaltional awareness system in GRASS.<br>
I figured out this sequence of action :-<br>
I create a DB in
which there is a table which hold location info about different
entities <br>
(Say two / three different types of vehicles). <br>
I load these onto the map display and view the data.<br>
Whenever I get a
location update on any of the entities I update the info on the table.<br>
I run a script in the background which keeps reading the table and<br>
displaying the entities in a endless loop - this should reflect any changes I carryout in the<br>
database.<br>
Now for the implementation :-<br>
I have downloaded and compiled postgresql on my machine buy since GRASS was initially<br>
configured without postgresql how do I enable it .<br>
Do I need postGIS for this kind of task?<br>
Lastly , are there any errors in the sequence of action listed above ?<br>
Thanks in advance<br>
