Low-altitude remote sensing dataset including DEM and RGB mosaic for AB transect and Site0-L2 corridor. Processing flowchart for each corridor: Ground control points (GCP, 20.3 cm square white targets, every ~20 m) surveyed with RTK GPS. Acquisition of RGB pictures using a Kite-based platform. Structure from Motion based reconstruction using hundreds of pictures and GCP coordinates. Export of DEM and RGB mosaic in geotiff format (NAD 83, 2012 geoid, UTM zone 4 north) with pixel resolution of about 2 cm, and x,y,z accuracy in centimeter range (< 10 cm). High-accuracy and high-resolution inside GCPs zone for L2 corridor (500x20m), AB corridor (500x40) DEM will be updated as needed. Only zones between GCPs have <10 cm accuracy although all the mosaic is provided.
