Adrián Martínez Fernández, the technician in charge of the Digital Mapping and 3D Analysis Laboratory at the Centro Nacional de Investigación sobre la Evolución Humana (CENIEH), is the lead author of a paper published in the journal Remote Sensing on how the properties of images captured by drones influence the representation and monitoring of high-mountain environments in photogrammetric surveys. This study, in collaboration with the CENIEH geologist Alfonso Benito Calvo, sets out the possible pitfalls of employing images from low-cost drones, and how these can be mitigated.
