【摘要】 针对基于TIN数据结构的汇水淹没分析存在地形因子计算难以实现、数据处理时间较长等缺点,选择利用规则格网数据结构,能够容易实现地形因子计算,准确得到水流网络图,经与实际研究区域对比,证明了其可行性和正确性.更多还原

【Abstract】 The traditional research of catchment and submerging is based on TIN data structure,which is not easy to achieve terrain factors and the data processing time is long.This paper can more easily realize the calculation of terrain factors and get accuratly flow network diagram by using the regular grid data structure.At last,comparised with the actual study of regional,it can prove its correctness and feasibility.更多还原
