Application of terrestrial‚ 'structure-from-motion' photogrammetry on a medium-size Arctic valley glacier: potential, accuracy and limitations
Terrestrial photogrammetry was the standard method for mapping high mountain terrain in the early days of mountain cartography, until it was replaced by aerial photogrammetry and airborne laser scanning. Modern lowprice digital single-lens reflex (DSLR) cameras and highly automatic and cheap digital...

Terrestrial photogrammetry was the standard method for mapping high mountain terrain in the early days of mountain cartography, until it was replaced by aerial photogrammetry and airborne laser scanning.
