my 2cents 1) @Edgar: I have not heard about problems with your plugin. The only lack is its userfriendlyness. But projections are thought for expert users, and not for day to day gis users.
2) I had a go with the newer geotools code (Edgar uses older libs) about a year a go but stuck with some problems (the example provided at the webpage did not run, since they changed some thing.. i think we talked about that issue). Since that time i had no time to try again. 3) the internal JUMP projection stuff is nice but very limited. the problem - if we go further with that and not use geotools - is that we would need to reinvent the weel. 4) how to do: for simplicity i would recommend to have a layer-menu item that allows you to reproject the data - for a first version (using the EPSG codes). In and out coordsystems have to be provided! Transformed data could be put to a new layer? Hence, no "on-the-fly" projection. Further i think that transformed data are saved only if the user explicitly wants to save (lets call it export). i did not yet thought about database stuff - this would need to set a projection for the current view, to receive the correct data (actually there is the SRID plugin/property for every layer to support the work with the postgis plugin that does something similar). 5) from my point of view we do *not need* to hurry with implementing it because a) Edgars plugin works for the wector data (as far as i know) b) projections are something for experts. Something what i learned here at this uni is that people want to project something to somewhere, but have no clue what this means. (actually most people rather wonder why things do not fit - and after a while they realize that it has something to do with coordinate systems) but a offer from Jody to help is of course nice offer stefan PS: as sunburned realized.. he has a lot of projects.. so i would also rather recommend to reschedule the projection project at an unknown date Edgar Soldin schrieb: > Hello all, > > are there known bugs or problems, which prevent cts extension from > running in openjump?
