Crowd-sourcing structure-from- motion data for terrain modelling in a real-world disaster scenario: A proof of concept Structure-from-motion (SfM) photogrammetry techniques are now widely available to generate digital terrain models (DTMs) from optical imagery, providing an alternative to costlier options such as LiDAR or satellite surveys. SfM could be a useful tool in hazard studies because its minimal cost makes it accessible even in developing regions and its speed of use can … Continue reading “Crowd-sourcing structure-from- motion data for terrain modelling in a real-world disaster scenario: A proof of concept” Learn More
