Bathymetric lidar data from the Blue River, Colorado, October 18, 2018


Publication Date


Legleiter, C.J., and Kinzel, P.J., 2019, UAS-based remotely sensed data and field measurements of flow depth and velocity from the Blue River, Colorado, October 18, 2018: U.S. Geological Survey data release,


The U.S. Geological Survey contracted with Juniper Unmanned to conduct field tests of the ASTRALiTe bathymetric lidar system on the Blue River just upstream of its confluence with the Colorado River near Kremmling, Colorado, on October 18, 2018. The objective of this project was to assess the potential to map river bathymetry (i.e., channel bed topography) using lidar data collected from an unmanned aircraft system (UAS). The ASTRALiTe lidar instrument was mounted on a DJI Matrice 600 Pro UAS owned and operated by Juniper Unmanned. As part of the study, Juniper's pilot flew the ASTRALiTe instrument across 2 river transects (cross-stream) on the Blue River. This data release includes data delivered to the USGS by ASTRALite on November [...]

The U.S. Geological Survey has an ongoing research interest in developing and testing innovative technologies for remote sensing of river bed topography as one component of an integrated approach to non-contact measurement of river discharge. High-resolution measurements of bed topography are increasingly used to support scientific investigations and resource monitoring because such data afford numerous advantages for geomorphic change detection, physical habitat characterization, and numerical modeling of flow and sediment transport.
