[postgis-users] simple puffer script

2011-08-23 Thread Robert Buckley 
Hi,

I have to use postgis to create a puffer layer. I could do this within postgis, 
but the problem is that I have to display the result in my webapp!

I have seen many examples on how to puffer, but none where a user inputs a 
value 
from a textbox e.g 50 and presses a button to calculate a puffer over the data 
with a 50m puffer and then displays the resulting vector layer in the 
openlayers 
map.


Is this very complex?
How should I start coding this?  PHP to script the postgis query? 

thanks for any scripts, tips or advice.

yours,

Rob you can do this with geoserver and it's sql view feature.  The docs cover 
it pretty well.
