[Pywps-dev] WebGIS development

[Jáchym Čepický]

Lorenzo,

there is no "best" technology for this task, rather then "complex 
technology".

Start with the map, get some vector datata in it, be able to identify 
some polygons and get their IDs. Once this is done, start with the 
process, which will accept those IDs and make proper calculations.

The glue it together

There is not much to be said about it - just do it.

Is that research, or commercial project?
