Physical Habitat Characteristics on the North Fork Shenandoah River, VA in 2002-2003

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).

本数据集采用PLGR制式政府配发GPS（PLGR government-issue GPS）与野外人工测量的方式采集所得。采集工作沿谢南多厄河北支（North Fork Shenandoah River）开展皮划艇作业时完成，每个点位均对应一处中尺度生境类型的转变节点。在人工测量覆盖区域内，GPS点位通过地理信息系统（GIS，Geographic Information System）衍生的点位进行补充。上述采集点位被用于生成线状覆盖图层，该图层可表征中尺度（即河道宽度）下的物理生境特征。
