通过自主研发技术,对网络影像服务(WMS)进行获取与存储,在CAD下将球面经纬度转化为大地坐标进行拼接;将GIS应用于铁路设计中,实现了道路网的自动提取与建筑物拆迁数量的自动统计等功能。将WMS应用于铁路选线设计,实现了网络空间数据的本地化应用。在铁路工程前期缺乏底图的情况下,将获取的网络影像应用于铁路选线设计,减小了设计前期对底图的依赖性。
Through the independent research and development of technology, the Network Video Service (WMS) is acquired and stored, the latitude and longitude of the sphere are transformed into the coordinates of the earth under the CAD for splicing. The GIS is applied to railway design to realize the automatic extraction of the road network and the quantity of building demolition Automatic statistics and other functions. The WMS is applied to the design of railway route selection, which realizes the localization of network spatial data. In the absence of the base map in the early stage of railway engineering, the acquired network image is applied to the railway route selection design, which reduces the dependence on the base map in the early stage of design.
