| 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 u- sing the regular grid data structure. At last, comparised with the actual study of regional, it can prove its correctness and feasibility. |
