Abstract
According to the geographical environment characteristics of railway location system, this paper puts forward the three-dimensional geological environment modeling method based on the integration of vector and raster, using remote sensing geological interpreted information in the virtual environment location design system, realizes the geological information positioning and the effective recognition in an internal computer based on the Vector modeling method, achieves Geological Remote Sensing accurate positioning in three-dimensional space based on the raster modeling method and triangulated irregular network (TIN) Model, Constrained TIN model, to directly express geological information by interpreting remote sensing images, establishes the expression and description model which exists at the same time of vector objects and raster images for geological objects. On this basis, this paper establishes a direct three-dimensional geological environment, and gives examples of railway location.
