Landslide inventory (1953-1996), Andrews Experimental Forest and Blue River Basin

Landslide inventory (1953-1996), Andrews Experimental Forest and Blue River Basin. This layer is a combination of data from four landslide inventory efforts that have been conducted in the area beginning in the late 1960's. Data represent landslide occurrences between 1953 and 1996. Data are in the UTM coordinate system; zone 10, NAD27. The data table that describes the characteristics of the landslides inventoried in the following: Individual layers tied to inventories by Ted Dyrness, Fred Swanson, Dan Marion, and Matt Wallenstein were appended and linked to the shape file. This file is associated with the slideinv layer, which is a combination of data from four landslide inventory efforts that have been conducted in the area beginning in the late 1960's. Points have been screen digitized from field maps using streams, roads, contour lines, and harvest units as reference layers.1953年至1996年滑坡清单数据集，覆盖安德鲁实验森林（Andrews Experimental Forest）与布鲁河盆地（Blue River Basin）区域。该数据图层整合了自20世纪60年代末以来在该区域开展的四项滑坡调查工作的原始数据，完整记录了1953年至1996年间的滑坡发生事件。数据采用通用横轴墨卡托坐标系（UTM, Universal Transverse Mercator），投影带为10带，基准面为NAD27。 用于描述所调查滑坡特征的数据表格如下：由Ted Dyrness、Fred Swanson、Dan Marion与Matt Wallenstein绑定至各调查任务的独立图层已追加至形状文件（Shapefile）并完成关联。该文件与slideinv图层相关联，而slideinv图层同样整合了自20世纪60年代末以来在该区域开展的四项滑坡调查工作的原始数据。研究人员以水系、道路、等高线与采伐单元为参考图层，从野外地图中通过屏幕数字化的方式提取得到滑坡点位。
