New publication: The potential of small unmanned aircraft systems and structure-from-motion for topographic surveys: A test of emerging integrated approaches at Cwm Idwal, North Wales

Highlights: An integrated sUAS and SfM approach is used to generate topographic data. The SfM dataset is compared with a total station ground survey. Causes of vertical difference between the two datasets are investigated. The integration of a combined sUAS and SfM approach is … Continue reading
