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
