We have used the swissTLM3D as the basis data of Outdooractive’s map of Switzerland.
SwissTLM3D is a digital representation of reality and contains as vectors not only man-made features (buildings, streets), but also natural ones (terrain, relief). It is the most accurate and complete data set available for Switzerland and is also used in the production of the National Map.
With swissTLM3D we are able to create a high quality map with unique styling for summer and winter. Using this data also allows us to create our activity-based routing- meaning that the map and your route will always fit together perfectly.
Another advantage of swissTLM3D as a data set is that it already includes officially signposted hiking trails.
