Reliefs for navigation
Swiss Alpine Museum
A little pocket relief that could took along during a trip facilitated the navigation of people untrained in interpreting maps. Particularly before the spread of contour maps, a little model of the terrain could help finding one's way in mountainous regions. Carl August Schöll (1810 - 1878) created such a relief based on a map of 1813 created by Heinrich Keller (1778 - 1862).
