Elevation models (Digital Terrain Model, Digital Surface Model) and orthomosaic colour imagery from UAV-mounted LiDAR flown over sections of the Upper Tweed in southern Scotland. The resulting elevation model resolutions are approximately: Ortho-mosaics 0.02 m, DSM 0.04 m, and DTM 0.1 m resolution and cover an area of approximately 0.5 km^2 (Tweedsmuir) and 0.29 km^2 (Hearthstane Burn) at the confluence of the River Tweed and Hearthstane Burn.
The data were produced as part of the Floods and Droughts Research Infrastructure (FDRI) which is installing monitoring equipment across the Upper Tweed. FDRI is expected to produce repeat surveys of elevation to understand geomorphological change from flood events.
This work was supported by the Natural Environment Research Council (NERC-UKRI) as part of FDRI. FDRI is a collaborative effort coordinated by the UK Centre for Ecology & Hydrology (UKCEH) in partnership with Imperial College, University of Bristol and the British Geological Survey.

Provenance & quality
A number of flights were undertaken across the area using a DJI M350 drone carrying a DJI L2 LiDAR. An Emlid RS3 multi-band RTK GNSS receiver was used as a base station with PPK (Post-processed Kinematic) processing used to calculate and correct positional errors of the LiDAR trajectory. The LiDAR data was processed using the DJI Terra software with "Merged Output" enabled to join the multiple contiguous flights for each of the areas together.
