Thanksyou,
I use you example and I reach my goal!.
is there any description on the way OJ project is organized for development?
I mean who is working on what..
I'd like to give some contribution even if I'm a newbee on java.
For example I need a lot to manage 3D geometry and even if OJ is,
after GRASS the best opensource tool for 3D there are still some basic
lacks.
Some examples:
- postgis plugin doesn't support 3D (also shptopgsql doesn't) I need OGR for it.
- some tool like move geometry drops Z
and so on
I'd like to make a revision on code for some of them. Someone is
already working on these aspects?
