【Abstract】 This paper analyzes the shortage of Microstation’s GIS framework and the structure of vector topographic map in it, and uses VBA to build a middleware which is able to distill, store, query and output the vector data. It builds the spatial property database to manage the vector data and the property data synchronously in SQL2000 Server. According to these technologies, the fundamental GIS for Daqing oilfield is built on the Microstation platform, and GIS functions is realized in CAD system.更多还原
