We introduce three lightweight interactive camera control techniques for 3D terrain maps on touch devices based on a look-from metaphor. These techniques complement traditional touch screen pan, zoom, rotate, and pitch controls and allow viewers to quickly transition between top-down, oblique, and ground-level views... Spot heights and soundings indicate terrain elevation. We propose a method for the automated selection of spot heights locations representing peaks, saddles and depressions. Our results are close to reference spot heights produced manually by swisstopo cartographers...
