Get spatial intersection through attributes in WFS

Rate this Message:
Hi,
I need to get the intersection area of two features in the same layer, the tutorial shows that you need to pass the geometery of both features , is it possible to define attributes of feature instead of its geometry and get the spatial intersection. for example Intersect('attrib=1',attrib=2) or do I need to extract the poslist at the client end for both features and then pass the geometries to the function?
thanx
Imran

Hi Imran,
Yes, you will need to the later. WFS only specifies how to deliver data, doing any sort of processing on it, or deriving any sort of data is out of range of the spec and more inline with WPS which is something being worked on but still experimental. -Justin Imran Rajjad wrote: > Hi, > > I need to get the intersection area of two features in the same layer, > the tutorial shows that you need to pass the geometery of both features > , is it possible to define attributes of feature instead of its geometry > and get the spatial intersection. for example > Intersect('attrib=1',attrib=2) or do I need to extract the poslist at > the client end for both features and then pass the geometries to the > function? > > thanx > Imran > > -- > I.R > > > ------------------------------------------------------------------------ > > ------------------------------------------------------------------------------ > Come build with us!

Hi,
thnx for reply, well i did put the same sort of question in another thread, in which version can you use the WPS service, otherwise do i need to make a servlet using JTS and add it to GS? is it possible or do I need to make the whole calculation thing at client end! I`ve already done that for cliping linear features according to bbox but the polygon intersection algo is not that easy to implement in the limited scripting language regards, imran On 11/6/09, Justin Deoliveira <jdeolive@...> wrote: > Hi Imran, > > Yes, you will need to the later.
