Uppsala / 1:10 000

These four topographic maps of Uppsala were published in 1982 and 1983 by Lantmäteriet, Sweden.

They are from the 1:10 000 ‘Ekonomisk karta över Sverige’ series, which uses several thousand orthophotomaps to cover most of the country. As you can see, an orthophotomap is based on aerial photography. But, using special methods, each frame is corrected for height and tilt, such that it will fit the surrounding frames, and form a mosaic having the same positional accuracy as a map.

These ones have features which are uniquely Swedish:

  1. Notes advise that the land is rising by 4.9 mm every year. This post-glacial rebound is important for the planning of harbour and drainage works. Now that the last Ice Age appears all too definitively over, will future maps need to indicate sea level rise?
  2. Bright yellow areas. These depict åker, or fields likely subject to allemansrätten – the public right to travel, by unmotorised means, across the open countryside.
  3. Outside of the city, each plot of land is shown with its lot number. In Sweden, both land ownership and individual tax returns are classed as public information.

Several thousand of these maps are available from TROPICARTA (requires Chomikuj account).
