Research on remote sensing applications and 3D visualization for railway location

摘要

Giving a full consideration of the environment protection in determining the railway location for the purpose of the sustainable development, with the help of remote sensing, GIS, 3D visualization and virtual reality technology, combined with the field geological survey, this paper conduct the remote sensing applications and 3D visualization researches of the Passenger Transportation Special Railway Line from Shijiazhuang City, Hebei province to Taiyuan City, Shanxi province. The research results show that remote sensing information has provided reliable references for the project-design selection of the Shi-Tai Passenger Transportation Special Railway Line in the general investigation of regional structures and geologic hazards; the 3D visualization analysis method based on the virtual reality technology has provided a new tool for the direct, interactive and scientific description in the railway location.
