Steven Sobieszczyk 2010 vector digital data http://water.usgs.gov/lookup/getspatial?insantiam_Hydrography LiDAR-derived (hydrography) stream network. This data set represents the river network for the Little North Santiam River Basin, Oregon. Using light detection and ranging (LiDAR) high-resolution imagery, stream centerlines for rivers, streams, and gullies were digitized. Mapping completed at 1:4,000 scale. Names of rivers and streams based on those from Oregon Atlas and USGS topographic maps. Data set has 3D component based on elevations querried from LiDAR imagery. 2009 ground condition Complete None planned -122.583134 -122.133505 44.900483 44.778859 None streams rivers gullies inlandWaters hydrography LiDAR None Little North Santiam River Elkhorn Mehama Lyons Oregon Marion County None 2009 None.

Horizontal error was +/- 1 ft based on LiDAR accuracy estimates. Snapping tolerance set to nodes and vertices during digitizing to avoid dangling nodes and isolated networks. Data are topologically correct in ArcGIS. Data are complete. Oregon LiDAR Consortium 2009 remote-sensing image online 2009 publication date LIDAR2009 Used as digitizing basemap or source. LiDAR digital elevation model was converted to a slopeshade model. Linework was manually digitized along river, stream, and gully centerline. Linework mapped at 1:4000 scale and extended as far as what was visually discernable. 20100610 17570200 Streams were annotated based on referenced stream names from Oregon Atlas, USGS topographic maps, and other digital USGS hydrography networks.
