* We support spherical stuff at the interface level (in GeoAPI): http://geoapi.sourceforge.net/snapshot/javadoc/org/opengis/referencing/cs/SphericalCS.html * Geotools can creates GeocentricCRS instances with either a SphericalCS or a 3D-CartesianCS. I will call that GeocentricCRS[SphericalCS] and GeocentricCRS[SphericalCS] in the discussion below. * Geotools already support coordinate operations involving GeocentricCRS[CartesianCS]. This is supported for example in Geographic <--> Geocentric[Cartesian] conversions. * The main missing piece I can see is a GeocentricCRS[CartesianCS] <--> GeocentricCRS[SphericalCS] MathTransform implementation. Since the cartesian <--> spherical formulas are very well known and rather simple, such implementation should be trivial to write (using an existing MathTransform implementation as a template). * The most tricky task is to update CoordinateOperationFactory once the above MathTransform is available. I would take care of this work. Martin. ------------------------------------------------------------------------- Using Tomcat but need to do more? Need to support web services, security?
