Seamless quantification of wet and dry riverscape topography using UAV topo-bathymetric LiDAR

Data to accompany journal article published in MDPI Drones. The data included in this record is from a trial of the YellowScan Navigator, UAV topo-bathymetric LiDAR unit (pre-production demonstration prototype instrument) over a reach of the River Feshie, Scotland (14th & 15th August 2024). 

All datasets are provided in OSGB36(15) British National Grid (EPSG: 27700).

The datasets include:
- processed topo-bathymetric point cloud (.las format)
	- 10,050,006 pts (average point density: 62 pts/m2)

		- 2 - Ground (5,388,266)
		- 7 - Low Point Noise (56)
		- RESERVED CLASSES (BATHYMETRY)
		- 40 - Reserved (280,614)
