摘要
以丰宁县下庙水库为研究对象,以SRTM高程数据为基础,利用ArcGIS空间分析功能,实现了对无地形图地区工程位置处流域面积的提取及计算,经与传统方法进行对比分析,证明了方法的可行性。
Based on SRTM elevation data of Xiamiao Reservoir in Fengning county,the extraction and calculation of the basin area is obtained by using the spatial analysis function of AreGIS software, the project location without topographic maps .And compared with the traditional method ,the result showed the method based on ArcGIS is feasible.
