Question.. should we make a new email list on sourceforge for the GSofC 
emails?
==============================
Hei,

just in general I would like to see first some "dry case studies".. i.e. 
some concrete examples on what you want to accomplish. Such a case study 
is oriented on a task which an "enduser" should accomplish. For instance:

The Task is, to calculate the Union of 2 Layers and to colour the result 
layer with respect to attribute X. (or in terms of an example: The GIS 
Analyst should make a map which shows where TV station XY can set new 
broadcast stations)

Now.. we can go and anlyse this task on:
- necessary input data
- required functionality (GIS functions, UI functions)
- workflow (A->B)
- output format

and so on...

If we have 2-5 such case studies, then we can start to think about the 
overall concept. The idea is then, that at the very end, this taks can 
be fulfilled with the tool. It is now up to you (Leandro) to develop 
such case studies first (some examples you can get for instance from the 
Tutorial by Uwe or from another GIS book/course).
Note: examples can be very complicate, if we want to include loops (if, 
then) and conditions or something like that.

If you have setup the previous.. (maybe with sketches) then we can think 
about implementation (how to do them).

Furthermore, you should study (if the software is available to you) the 
geoprocessing functions in ESRIs ArcGIS, besides Sextante. Also ERDAS 
Imagine has something like that. And.. then I had also sent a link to a 
this article: http://ica.ign.fr/Portland/paper/ICA2006-Petzold.pdf , 
have a look on it too.

Finally to get yourself known with OpenJUMP.. have a look on the 
openjump wiki in the documentation section. There I outlined how one can 
program with OpenJUMP (e.g. make a plugin)

I hope the others agree
Stefan
