Application of WMS Data Services to Large-Scale Engineering

Focusing on the civil engineering design,we explore an efficient,integrated engineering design and application prototype system using shared Web Map Service(WMS) data.First,directly targeted on WMS data server,a WMS data acquisition application program is implemented based on WMS public access protocol with efficient parallel multi-threaded network transmission of spatial data tiles,as well as double access mechanism combined local caching with network share strategy.Second,the prototype system achieves WMS remote data localization simulated application and distributed collaborative shared by independent download application program as well as embedded real-time threads.Third,fixing on the application of WMS data in engineering,we explore a series of tools such as coordinates transformation,image merging and CAD file produce,to promote the WMS data easily converted to all kinds of different plane engineering data with high-precision.Finally,We take full advantage of WMS data organizational characteristics and develop an unified global 3D prototype platform to express and integrate various WMS data sources.The experiments show that the techniques and methods we adopted are effective and efficient.
