Topological study on the position of building in mining area

摘要：

When visualizing the damages of underground resource mining using GIS (Geographical Information System)technology,it is necessary to evaluate the spatial relationship of different geographical elements.Based on the unique GIS topology,this paper abstracts the relationship of spatial location between subsidence area building and subsidence isoclines to models,and then discusses the topological arithmetic of points and curves and their flows.And,this study that topologies the geographical elements and visualizes them can provide decision support for protecting building,which provides reliable information for monitoring the subsidence in mining area.
