Experiment and Research of Google SketchUp Combine with ArcGIS in the Three-Dimensional Urban Geographic Information System

In order to establish the city three-dimensional Geographic Information System, combine with the current emerging technologies of three-dimensional Geographic Information System, to explore a new method to open out 3D GIS by integrating Google SketchUp and ArcGIS. The results show that: Google SketchUp combine with ArcGIS can set up the 3D city model quickly, however, the 3D spatial query and analysis functions of GIS is difficult to achieve, can only choose C#.NET as the development platform and ArcGIS Engine as software development kit, to realize some functions such as three-dimensional roaming, integrated query, buffer analysis, underground pipeline explosion analysis, etc.; The results may have some reference value in the three-dimensional spatial data model and data structure, three-dimensional spatial data management and spatial data analysis and visualization of expression.
