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.
