Donald C. Hayes Peter M. Ruhl Jennifer L. Krstolic 2010 This dataset was collected with a PLGR government-issue GPS, and through manual measurement in the field. Points were gathered while canoeing along the North Fork Shenandoah River. Each location marked a change in meso-scale habitat type. GPS points were supplemented with GIS-derived points in areas where manual measurements were made. The points were used to generate a line coverage. This coverage represents physical habitat at a meso-scale (width of stream). application/pdf 10.3133/70046258 en U.S. Geological Survey Physical Habitat Characteristics on the North Fork Shenandoah River, VA in 2002-2003 reports
