[http://sourceforge.net/projects/karto karto] needs java and is released under GPL.

<blockquote>Karto allows to calibrate a scanned map with some known geo-points (Lambert, UTM, ...). After that, you can add any points (GPS points) in the map to build your own map. You can also add a transparent GIF image in the map after calibration (cave or mine). It doesn't work with common genealogical formats but with most images and textual masks. Useful if you want to display ancestors on your old map.</blockquote>
