Field spectra from the Niobrara River, Nebraska, August 15-18, 2016 The U.S. Geological Survey collected field spectra collected from the Niobrara River in Nebraska August 15–18, 2016, to support research on remote sensing of river discharge. Reflectance measurements were made by wading the Niobrara River near Norden Notch using an Analytical Spectral Devices FieldSpec3 spectroradiometer operated in reflectance mode. The original *.asd files are provided in this data release.

These data were obtained by conducting topographic surveys with Trimble R8 and R10 RTK GPS receivers with a local base station and also by measuring depths with a SonTek RiverSurveyor S5 acoustic Doppler current profiler (ADCP). The data are provided in a series of tables saved as *.csv files. All tables include, at a minimum, easting and northing spatial coordinates and depths; other attributes in some of the tables include descriptive...
