Research on Spatial Data Model of Automated Route Siting for Power Lines

The design of data model is the key problem of achieving automatic power route siting.Presently there is some discussion on the raster data model.Based on it,this paper presents a multi-grid spatial data model for power line siting.It integratedly uses the advantage of raster and vector spatial data models.And it can adaptively select the gird of different levels to participate in the statistics of the influencing factor’s cost value and the calculations of optimum paths on the basis of the terrain and the complexity of influencing factor in the route siting area.At last,this model is used to the experiment of power route siting via A* algorithm.The results show that the multi-grid spatial data can improve the rationality of route siting strategy.
