DESIGN AND IMPLEMENTATION OF FUNDAMENTAL INFORMATION PLATFORM FOR QINGHAI-TIBET HIGHWAY BASED ON GIS
摘要
Abstract
In the paper we study the building technology of uniform fundamental information platform for subgrades construction in Qinghai-Tibet Highway permafrost region, and provide technical support to related scientific research and production. We make the analyses on current status of data and software tools, as well as the software demand analysis and design, the implementation of the above addressed is based on ArcEngine GIS components, Oracle and Visual Studio. NET etc. Outcomes of our research mainly cover the following aspects: (1) we realise the first time the integrated management of multi-source heterogeneous data including the topographic map of 624 km section in Qinghai-Tibet Highway permafrost region, HD video, ground temperature measurement section, ground thermometric hole and experiment section, etc. ; (2) by applying the vehicular 3D laser scanning technique to the research of Qinghai-Tibet Highway permafrost region, we collect a large number of point clouds data and real images, realise the functions of standardised data management, quick browsing and terrain analyses, these significantly improve the accuracy of data along the highway and the visualised effect; ( 3 ) we achieve the spatiotemporal analysis function of the ground temperature at cross-section of the highway, can conveniently extract the permafrost table and isotherm, etc. , and can realise the spatiotemporal variation analysis on the ground temperature of permafrost. Compared with non-GIS approaches, our analyses outcomes possess the practical geospatial connotation.关键词
