A 3-D VR MODEL FOR OPTIMAL ALIGNMENT SEARCH SYSTEM OF HIGHWAY DESIGN (OHPASS) USING ASTER GDEM

摘要

This study developed a function in OHPASS, Optimal Highway Path Automatic Search System, to allow it to use ASTER Global Digital Elevation Model (ASTER GDEM) that covers all the topographic data in the world. In addition, we have constructed a system that enables output files from OHPASS to be viewed and evaluated as a three-dimensional (3D) virtual reality (VR) model. The system can be used for landscape evaluation and road structure evaluation in road alignment planning, and for consensus building with concerned parties throughout the world using OHPASS.
