Hi, a) deegree 2 is now in a more or less stable state. That means probably we will not have major changes at the current code base of deegree 2. Indepent of this, we have started planning for next major release of deegree (deegree 3). But this is not so important if you are goning to use deegree for your developments now (on next deegree day - 18.6. in Bonn - we will present state of current planning)
b) deegree and so deeJUMP had used proj4 connected by JNI for CRS and CRS transformation implementation. Unfortunately this has not been very stable because of different reasons, so we started implemneting our own API. This is now in a stable state (additional functions and supported projections still will be added) and more or less indepent of other deegree components, so it easyly can be used outside of deegree. It is true that we developed a simple and easy to understand XML synthax for describing CRS and transformations but to be compliant with other source we also started to develop converters. At the moment a converter for proj4 crs definition is available; converters for GML3 and EPSG database will follow. I hope this clearifies the situation of deegree's development state. best regards ANDREAS Sunburned Surveyor schrieb: >Stefan, > > >You wrote: "Hei.. did you know that we talked a while ago to the >Deegree people on >that subject (Lat/Lon).
