New mapping of the Swedish-Norwegian border

Work on a new mapping of the 1,630 kilometer long Swedish-Norwegian border started in 2020 and is to be completed in 2024. Now the border is sharper than before, reports SVT Nyheter. When the previous mapping was done, GPS technology did not exist. Many of the cairns that mark the border have existed for several hundred years and have not been precisely placed.

The border is now measured with centimeter precision. The mapping work between Svinesund in the south and Three-Country Cairn in the north takes place largely in roadless country. Just getting to the Three-Country Cairn requires a boat trip across Lake Kilpisjärvi and then a three-kilometre walk.

Transport of personnel and material is often carried by helicopter, and some parts of the road actually have to be climbed.
