In MapWindow GIS you can view the current coordinate system of a georeferenced image. Just use View/Add Layer to display it, then in the table of contents/legend double click the layer to view its properties. You can also reproject your image from one system to another using the "GIS Tools"...
Hi all,
We're quite excited to see a SWMM5 GIS interface for MapWindow GIS. This is exactly the kind of lightweight GIS interface use that MapWindow was developed for. Hopefully it will go well and get widely used...
As for running in WINE, I'm not sure if MapWindow runs under that...
