I just learned that two very nice sets of old, out-of-copyright Swedish maps have been made freely available. Maybe they have already been around for a while, but I just learned this now. One set is the topographic map (popularly called Generalstabskartan) in scale 1:100,000 for southern and 1:200,000 for northern Sweden. The other is the economic map (Häradskartor) in more detail.
These maps have long ago been digitized by the Swedish ordnance survey (Lantmäteriet), but they don't allow downloading and reuse. Now, however, they have been (digitized again? and) made freely available by Stockholm University library, http://kartavdelningen.sub.su.se/kartrummet/kartskapet.htm
The maps are scanned in 600 dpi and are available in TIFF and JPEG. Some have also been geo referenced and have TFW and KML files for download.
Can we somehow get these huge bitmap images into a tileserver? They need of course be stretched to fit the coordinates, and the borders and overlaps need to be aligned. What tools are available for that? Would WMF support and host this? Would OSM? If someone can do this for a fee, maybe the Swedish chapter can find the money.
