Daumensprung und Jakobsstab. OutdoorHandbuch

How wide is the river? How deep is the gorge? Will we still be able to reach this mountain? Accurately answering these questions can be crucial in the wild. Estimating heights, depths, distances, and angles is quite challenging, even with considerable practice and experience, and often one can make significant mistakes. However, with a few tricks and a bit of geometry, one can perform reasonably good, relatively precise surveying work. This outdoor manual presents common as well as lesser-known methods for indirectly measuring distances, heights, depths, and angles. All measurements can be conducted without or with very simple technical aids; the methods are straightforward yet scientifically accurate. For better understanding, the theoretical basis and practical application of each method are explained.
