Reston, VA U.S. Geological Survey https://doi.org/10.5066/P9K54WDL The U.S. Geological Survey (USGS) National Geospatial Program (NGP) and National Research Program (NRP) acquired hyperspectral image data from the Kootenai River near Bonners Ferry, ID. The image data extended from the Kootenai Tribal FishHatchery downstream to the Copeland bridge. Image data acquisition occurred on September 27, 2017. A field team collected ground truthing data within the project area to calibrate and validate estimates of water depth derived from the hyperspectral image data. Multibeam echosounder (MBES) bathymetric data were collected at 6 sites within the area encompassed by the hyperspectral image to obtain high-resolution bathymetric data. Bathymetric data were collected at select sites along the Kootenai River in northern Idaho, September 26-27, 2017, to support research on sturgeon habitat, dispersion processes, and geomorphic change along the Kootenai and, more broadly, remote sensing of rivers. 20170926 20170927 ground condition Complete As needed -116.43796192277 -116.33359180558 48.833124800866 48.677399811087 None topography swath bathymetry Hypack Hysweep USGS ASCII Geology inland waters Bathymetry Water Depth River Multibeam echo sounder XYZ U.S. Geological Survey ISO 19115 Topic Category inland waters bathymetry elevation islands lidar lakes capacity USGS Metadata Identifier USGS:5bf48b5ae4b045bfcae2530f Geographic Names Information System (GNIS) USA Kootenai River Idaho ID Bonners Ferry None These data not intended for navigational purposes.

National Oceanic and Atmospheric Administration 2018 User Guide accessed January 29,2018 Washington, D.C. National Oceanic and Atmospheric Administration https://vdatum.noaa.gov/docs/userguide.html Quality assurance (QA) and quality control (QC) are critical with MBES surveys to maintain the highest degree of accuracy. Qualitative notes documenting anything that might affect the quality of the data, such as wave action, macrophyte growth, poor GPS quality, and any other observation that could degrade the bathymetric data were recorded in the daily field log. Prior to and during the survey, unique tasks were conducted at specified intervals to prepare the MBES system for bathymetric surveying, but also to describe the total estimated error within the system. Quality-assurance elements were developed following the input requirements of the Total Propagated Uncertainty (TPU) feature built into Hypack software. The TPU required a description of the general, environmental, and sensor settings to best estimate the total error potential in the survey data. A patch test ensured the MBES system was correctly offset and calibrated. The offsets from the patch test were applied to the system prior to the surveys on the Kootenai River. Data was collected at 12 select sites. Data was collected from bank to bank and in some cases, and longitudinally in other cases to capture sand dune formations. Edited raw data are presented in a generic ASCII XYZ format in the most raw form so that it can be used in various types of geospatial software applications. Gaps may exist in the coverage due to erroneous data spikes, macrophyte growth, instream hazards (submerged trees), or non-kinematic positioning. Missing data largely existed near the edges where macrophyte growth was prevalent along with submerged trees or other anthropagenic obstructions (docks, etc). The average horizontal uncertainty of the multibeam system was minimized as part of the patch test process. The positioning uncertainty largely depends on the GNSS RTK positioning precision. The average vertical uncertainty of the multibeam system is variable depending on depth. Bathymetric data were collected in the field using the Hypack software Hysweep. The bathymetric data were collected using a multibeam echosounder (MBES) system mounted on a USGS-owned and operated 25-foot jet boat research vessel. The echosounding component included a 240 kHz ODOM ES3 multibeam echosounder capable of projecting 480 beams spanning a max of 120 degree swath (width of coverage). For the surveys on the Kootenai, 480 beams were selected and the port and starboard angles were limited to 50 degree per side for a total angular coverage of 100 degree. A Teledyne TSS DMS-10 dynamic motion reference unit accounted for heave, pitch, and roll of the vessel. Two Digibar Pro sound velocity probes (velocimeters) were used to profile the speed of sound underwater. One velocimeter was mounted and operated real-time near the MBES to account for spatial change in the surface speed of underwater sound. The second velocimeter was used to acquire a depth profile that recorded how the speed of underwater sound varied by depth. A Trimble R8 GPS receiver mounted over the MBES was radio linked to the Washington State Real-Time Network to provide real-time horizontal and vertical positioning. A Hemisphere VS111 dual-GPS system was used for the heading and to output a 1 pulse per second (1PPS) output. An ODOM Real-Time Appliance (RTA) was used to time stamp the MBES, motion reference unit, real-time velocimeter, RTK-GPS positioning and elevation, and precise heading data to within 1 millisecond based on the 1PPS signal from the Hemisphere VS111. The RTA output the bathymetric data to two laptops, one for data acquisition and one for data processing. In addition, a Hummingbird side-scan was used for qualitative purposes to verify and note unique features (trees, sunken cars, sand dunes, clay steps and benches) to the channel bathymetry. A daily field log of the bathymetric surveys was kept to record the equipment used, crew members, referenced survey bench marks, sound velocity profiles, file names, and other ancillary information. 20170927 The raw data were then edited using Hypack MBMAX software. All raw data were initially filtered to exclude the outer 10 degrees of the multibeam swath. These data were out of tolerance and therefore excluded from the final data. Areas of missing data referred to as holidays occurred within the dataset due to the filtering of macrophytes, editing of erroneous data points, and areas where it was too shallow to allow complete coverage. 20180124 The edited data were reduced to a 1-foot gridded cell size as XYZ ASCII data using Hypack Combined Uncertainty and Bathymetric Estimator (CUBE).Soundings outside the TPU limits were excluded.
