安塞纸坊沟流域1:1万地貌图（1995年）

数据集为安塞纸坊沟流域地貌图，比例尺为1:1万，时间为1995年，数据为矢量格式。王东沟地貌类型包括冲沟、切沟、梯田、河沟、黄土梁等12个地貌类型。数据基于地形图编制工作底图，参考1:1万原始DEM和1:1万土地利用图（草图）等手工编制，然后根据现场调查进行修编，编制成地貌类型图。再由手扶跟踪数字化仪数字化并给每个图斑赋属性值。经过必要的编辑修改后，做投影变换。

This dataset is a geomorphic map of the Zhifanggou Watershed in Ansai, with a scale of 1:10,000, finalized in 1995, and stored in vector format. The geomorphic types within the Wangdonggou area consist of 12 categories including gullies, incised gullies, terraces, stream gullies, loess ridges, and others. The map was manually compiled using a topographic map as the base, with reference to 1:10,000 original DEMs and 1:10,000 sketched land use maps, then revised based on field investigations to produce the formal geomorphic type map. Next, it was digitized with a hand-operated tracing digitizer, and attribute values were assigned to each polygon. After necessary editing and modification, projection transformation was performed on the dataset.
