Online data acquisition of multi-geographic information platform & applicationresearch on the system of EV-Globe power line selection

With the continuous innovation of data and technology of geographic information system, the selection of power line are taking more and more advantage of data from high-quality geographic information platforms, at the meantime, power line selection based on traditional paper map and map-base is getting gradually out of view.This paper shows the process of accessing online data from multi-geographic information platform directly or indirectly to the EV-Globe platform, and how the data will be applied to power line selection.There are two main parts about this technology, one is to use the free interface released by Google Earth, Microsoft BingMaps, Sky Earth and some other mainstream geographic information platforms to obtain online image map, and then pack the image map into data plug-ins, and then upload it to EV-Globe platform according to request to serve for power line selection.The second part is to download the data to local storage by pixel spelling method, seamlessly integrating the data into the traditional selection tools such as AutoCAD, which successfully combines new technology and traditional tools.The result shows that the technology can obtain high-precision image and elevation data effectively and accurately, and perfectly dock it with the existing work process, which will definitely serve for the selection of power line.
