This is a map with a wealth of detail that has never before been found over the Sälenfjällen. The terrain information in the map is based on airborne laser scanning. For the first time, cliffs, larger rocks, forests and streams appear with an accuracy that truly corresponds to reality. We have come to the conclusion that the best material for a map is Tyvek®. It is made of a synthetic fiber that makes the map completely insensitive to water and very tear-resistant. A Tyvek map will not tear in the folds or lose color when you use it.
