| Abstract: | This article analyzes the data structure of shapefile geometry data.Based on ADO.NET technology,we achieve a new method of importing shapefiles into ADO.NET datasets.Thus,we can save the spatial data of shapefiles into datatable,and make spatial data and attribute data to be managed synchronously.Further more,this give us an efficient method of building topology relationship for shapefiles. |
