Building 3D cadastral system based on 2D surveying plans with SketchUp
Three land dimensional development and utilization become the trend of urban planning in current metropolis. This paper presents a method for building a three dimensional cadastral management system from surveying plans with SketchUp. It concentrates on the geometric representation and topological consistent maintenance of 3D cadastral objects. In this system a complete topological model is built to express the body construction and spatial relationships among 3D property units. SketchUp is used to automatically construct 3D model with attributes and thematic information from 2D surveying plans. Spatial topological relationships and operations are analyzed with the programming and development of Ruby language. The resulting system can manage the 3D cadastral objects and manipulate them with spatial operations to support spatial analysis.
