UAS LiDAR, Sonar and Radar Altimetry dataset for river hydraulic characterization of Ryå stream

The different folders contain:

UAS_sonar_L1

• GNSS data from the reference base station
• GNSS data from the rover
• Sonar measurements with depth-measured values
• RTK reference water surface elevation

UAS_sonar_L2:

• Sonar_georef_*: Georeferenced sonar data with GNSS coordinates
• GNSS_time*: GNSS timestamp and corresponding coordinated
• Sonar_time*: Sonar timestamp, measured depth and NMEA sentence
• Sonar_georef_all_xsec*: Georeferenced sonar cross-sections with distance to the river centreline

UAS_sonar_L3:

• Xsec_sonar_"xsec number"_"chainage": Processed sonar cross-sections with bathymetry profile

Sonar_LiDAR_xsec:
