UAS-based very high resolution digital elevation models and orthomosaics of the coastal alluvial fan Guanillos, Atacama Desert

DOI

This dataset contains the very high resolution (<5 cm) digital elevation models (DEM) and orthomosaics (OM) of four survey areas at the coastal alluvial fan Guanillos (GUA) in northern Chile (21.97°S, 70.17°W). DEMs and OMs are based on aerial imagery acquired with a low-cost unmanned aerial system (UAS) on the 7th and 8th of March 2018. Imagery was processed using an optimized workflow for photogrammetric structure-from-motion (SfM) multi-view stereo (MVS) processing. The spatial resolution of the DEMs and OMs ranges from 2.8 to 3.2 cm and 1.4 to 1.6 cm, respectively. The raster geodata is stored in GeoTIFF format.
