Re: [Geoserver-users] Convex hull
Hi Ahmad, If you need this to be dynamic, the best bet is to use OpenLayers for your client. With a WFS layer configured to pull over the building features from Geoserver, you can let the user pick the buildings and then have a bit of _javascript_ to calculate and display the convex hull. The _javascript_ would get the all polygon vertices as an array of points and then feed them into the getConvexHull() function here: http://en.literateprograms.org/Quickhull_%28Javascript%29 This could then be displayed by Openlayers in fairly quick time.

You need WPS, there is a process that can compute the convex hull given two geometries expressed in GML Cheers Andrea -- --- Ing. Andrea Aime GeoSolutions S.A.S.

Hello all, I am new to Geoserver and to web GIS in general. I have a building layer that I want to be able to select two buildings and create a convex hull. Any suggestions.
