STUDIES OF THE RAPID POSITIONING OF 3D GIS BASED ON WEB GEOCODING

3D GIS technology has been developed gradually mature,3D GIS for the expression of the objective world can give people more realistic.However,the required data of 3D GIS software is massive,due to the development of remote sensing technology,the acquisition and processing of texture data has become easy and fast,collection and storage of the vector data is a very difficult task,It's a major challenge how to get massive,accurate vector GIS data in a short time,and to reduce the cost and time of data collection.By Web-Based Geocoding querying the geographic information of point features to store the geographical information to a local database.Data is applied to real-time positioning,quickly Locating and displaying in 3D GIS software.It provides services and extension function for developing various special 3D GIS software.
