| Abstract: | With the continuoiJs expansion of cities and rapid development of 3S technology, different departments acquire massive amount of geospatial data in different ways. The fusion of multi - source geospatial data has become a pressing problem in order to promote the sharing and utilization of geospatial information, reduce duplication of investment, accelerate the process of urban digitization and build up digital city geospatial framework. |
