Design and Implementation of Three-Dimensional Digital Campus Based on Sketchup and ArcGIS

With the mature of three-dimensional GIS technology, digital campus is gaining more and more attention as micro-reflection of digital earth. As current two-dimensional GIS has some limitations and much three-dimensional information cannot be fully utilized, with Sketchup three-dimensional modeling and ArcGIS three-dimensional analysis model as the base, we designed and realized digital campus of Hebei University of Technology from topographic map surveying, remote sensing map acquisition, geodatabases building, DEM production, main body construction modeling, and later function realization. This study provides new idea for campus planning, digital management and emergency solution.
