#GIS

Tried to twist my head around the Deegree library (http://www.deegree.org/) for a couple of months now, but it does not support spline curve geometries at all.

So I ended up generating the GML Java classes for our Application Schema (+ parts of the GML 3.1.1) using Apache XMLBeans, which worked pretty good. Now I still needed some good implementation for handling Geometry properties of the Feature objects. implementing geometry operations is not my field of expertise and I know there must be some good and fast implementations around.

GeoTools Geometry Plugin is still in hatching, it seems: http://docs.codehaus.org/display/GEOT...

I don't need any data storage capabilities as I get and store the Features as XML over network.

Our meteorology-related App Schema (in progress) is available at http://xml.fmi.fi/namespace/meteorolo...

Any experience or pointers?

Update:

GeoTools with its implementation of GeoAPI seems to solve at least part of the problems:

SplineInterpolator with a free licence can be found at least from Apache Commons Math -library: http://commons.apache.org/math/
