资源简介：
The ISC2010_VEGETATION_OVERHANG polygon features represent areas of vegetation that partially or wholly overhang the Stream Bed. The data set contains the whole vegetation polygon, not only the overhanging part of the polygon. Candidate vegetation is defined as vegetation cover greater than 20%. Vegetation Overhang has been mapped within a 200m buffer of the ISC2010_STREAMBED_WIDTH feature. This data set is derived from source Fractional Cover raster data. The data set also contains additional polygon divisions created by the introduction of Side and 200m buffer boundaries. Small polygons (
ISC2010植被悬垂（ISC2010_VEGETATION_OVERHANG）多边形要素指代那些部分或全部悬垂于河床之上的植被区域。该数据集包含完整的植被多边形，而非仅多边形的悬垂部分。候选植被的定义为植被覆盖度大于20%的区域。植被悬垂要素的制图范围限定于ISC2010河床宽度（ISC2010_STREAMBED_WIDTH）要素周边200米的缓冲区内。本数据集源自原始分数覆盖（Fractional Cover）栅格数据。该数据集还包含因引入侧边及200米缓冲区边界而生成的额外多边形分割区块。小型多边形（
