| 摘 要： | 面向大型土木工程设计,提出了一种运用WMS共享空间数据源并实现高效应用集成的工程设计应用技术体系。首先,直接针对WMS数据服务器定向开发数据获取应用,通过高效并行多线程实现空间数据的分块网络传输,同时结合本地缓存机制与网络共享,实现了一种双轨存储访问机制;其次,基于独立的应用下载与嵌入的实时线程分配,实现了远程数据的本地化模拟应用环境与分布式共享协同;再次,针对WMS数据的应用,实现了空间数据向工程数据的高精度转换与工程制图出图体系,开发了统一的全球三维可视化平台,用于直观地综合表达各种WMS数据源。 |

| Abstract: | 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. |
