A New 3DGIS Development Technology Research Based on the Sketchup and SuperMap Platform

Analysis the pros and cons with the current three-dimensional GIS development techniques, we proposed a new three-dimensional GIS development technology based on Google Earth, Sketchup and SuperMap software, to better achieve the virtual digital of the three-dimensional model. The Google Earth software gets the two-dimensional area to be modeling image which imports into Google Sketchup software, establishment of two-dimensional vector graphics, and then build roads and construction of three-dimensional models. Then, SuperMap component realizes the integration of spatial data and attribute data integration management, the realization of digital based on data collection, classification, storage of property data and management. Based on this, we applied the development technology to the virtual campus three-dimensional navigation system. In this, some technology flow charts are given. Finally, compared with some other three-dimensional GIS development technologies, a discussion and conclusion presented. We call to apply three-dimensional GIS navigation.
