But the world is not a sphere. Sad panda face. So things become complicated when trying to project a 2D image (the map) on 3D surface (the not so sphere like Earth) and then back again to a 2D screen. I am not going to bore you here with the whole theory of projections, datums coordinate systems etc.. They are failry well described in the Ilwis help and there numerous sources on the internet that give more information about this.

Ilwis 3.8 is almost done (sigh, finally) and apart from some bug tracking I don’t expect significant changes anymore. I am not sure if I will release it before my own holidays ( after 2nd week of february) but we will see.
Both these editors have been significantly changed. This was a side effect of having changed the drawing system of Ilwis. The way the old editors worked could not maintained in the new system and so I had to redesign them from ground up. This proved to be a more time consuming job then I had anticipated. Particulary in the segment editor there were so many states and state transistions to be reckoned with that I sometimes had trouble determining the right course of action. Anyway, I think I now have a working editor for both pointmaps and segment maps.
