The thesis' topic "gps supported and graphical editing of spatial information" is a new field to me though I am positive that through the great work of great work already done with geotools I'll conquer the *quest*. The final goal is an as sophisticated as possible java application, from the users point of view ;) .. realized in a 3 month time, including the explaining paperwork for the project and used technologies.

I saw this implemented in Jump, but couldn't find any georeferencing in it. So I am trying now to get familiar with JTS to work it out.

JTS doesn't support georeferencing besides the RFID, which should be a 
identifier for a spatial reference system. So does JUMP.

Geotools are based on JTS. JUMP is in much better shape for your work, 
but you will have to add support
for georeferencing and reprojection to it in order to effectively work 
with GPS data (WGS format) over some
kind of local projection. As a suggestion, I'd say you should try to 
modify Jump sources (georeferencing may be
introduced and handled in the feature collections I guess) in order to 
support
a bit of georeferencing using some of geotools modules, since doing the 
other way (adding all jump functionality
still missing to geotools) doesn't seem easy for a thesis that has to be 
done in three months. I'll be working
on GUI components and a JUMP alternative based on Geotools and the 
Netbeans code in the next few months,
but it will take quite a bit of time to develop it, so don't count on it :-(

Just an opinion
