Visualization of CityGML File Based on DOM and Spatiotemporal Indexing Tree
CityGML is a universal information model that used to represent 3D city model. Constitution and characters of CityGML is analyzed in this paper, based on which data structure is designed in parsing and visualization of CityGML file. DOM (Document Object Model) is used in parsing CityGML file, Time index model is established based on summarizing spatiotemporal feature of 3D city model of CityGML and then spatial index model is established based on R tree. Efficiency and effect of the proposed method is tested and conclusion is summed up.
