Fosness 2014 U.S. Geological Survey Data Series 889, 9 p Reston, VA U.S. Geological Survey http://doi.org/10.3133/ds889 The shaded relief raster data was created based on bathymetry obtained in the meander reach collected in about a one month period extending from 6/3/2010 - 6/19/2010. This subset data extends from river kilometer designator 228 upstream to 237. Similar methods used to collect and process the bathymetry are described in Fosness (2013). The shaded relief was created from a surface raster (also referred to as digital elevation model) of the bathymetry data and displays the illumination angle of the surface raster. The shaded relief data provides an appearance of three-dimensional space through the use of shading and lighting. The shaded relief raster data can be used to assist in describing the benthic habitat characteristics near current white sturgeon spawning grounds. The data may provide unrealized areas of species preferred habitat. 20110101 ground condition Complete As needed -116.418619 -116.381045 48.781395 48.732366 USGS Thesaurus topography swath bathymetry Hypack Hysweep USGS ASCII Geology inland waters Bathymetry Water Depth inlandWaters Multibeam XYZ U.S. Geological Survey ISO 19115 Topic Category inland waters bathymetry elevation islands lidar lakes capacity USGS Metadata Identifier USGS:f5b834e7-2e58-4932-abe9-7ee5aa6a5cb1 Geographic Names Information System (GNIS) Bonners Ferry USA Kootenai River Idaho ID None These data not intended for navigational purposes.

The data is complete. The positional accuracy of the contour data was not verified. The elevation data is thought to be accurate to within about 1ft. The bathymetric data were collected in the field using the HYPACK® software HYSWEEP®. The bathymetric data were collected using a multibeam echosounder system (MBES) mounted on a USGS-owned and operated jet boat research vessel. The echosounding component was a 240 kHz ODOM ES3 multibeam echosounder projecting 240 beams spanning a max of 120° swath (width of coverage). Port and starboard angles were limited to 50° per side for a total angular coverage of 100°. 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 MBE 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 MBE was radio linked to another GPS receiver set over a survey control point on land to provide real-time horizontal and vertical positioning. A Hemisphere® VS111 dual-GPS system was used to record the heading vector. 20100619 The raw data were then edited using HYPACK®’s MBMAX software. All raw data were initially filtered to exclude the outer 10° of the multibeam swath. These data were out of tolerance and therefore excluded from the final data. The edited data were reduced to a 1×1-meter cell size as XYZ ASCII data using HYPACK® Combined Uncertainty and Bathymetric Estimator (CUBE). Two hundred and forty beams were used for the survey and overlap of adjacent survey lines was between 75 and 100 percent. However, 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. 20100930 The ASCII XYZ formatted CUBE data were imported into ArcMap using the ASCII 3D to Feature Class tool and saved as point shapefile data. 20140101 A 1-meter resolution surface raster (digital elevation model) was interpolated from the point shapefile data using the Topo to Raster ArcMap tool. 20140101 A 1-meter shaded relief raster surface was created using the Hillshade ArcMap tool. The azimuth was set at 315 and the altitude was set at 45. 2014 The metadata was completed 20140401 raster Complete chain 30 NAD 1983 UTM Zone 11N 0.9996 -117.0 0.0 1640416.666666667 0.0 coordinate pair 0.000000007283507130750879 0.000000007283507130750879 foot_us D NORTH AMERICAN 1983 GRS 1980 6378137.0 298.257222101 North American Vertical Datum of 1988 3 meters Explicit elevation coordinate included with horizontal coordinates Shaded_Relief_2010 Gridded elevation, geographically referenced to the surface of the earth, as digital data USGS OBJECTID Internal feature number.
