VR-GIS技术是一门新兴技术,已经在很多领域得到广泛应用。本文基于ERDAS、ArcGIS、MapGIS等遥感和GIS专业软件,将VR-GIS技术应用到高压输电线选线中,制作康定-崇州500kv送电线路(大杠～沙坪段)走廊带的三维景观飞行模拟系统,再现研究区真实地形、地貌,使工作人员沉浸于虚拟环境中,为其分析和处理问题提供方便,解决因自然环境恶劣造成的外业调查困难等问题。

VR-GIS,an emerging technology,has been applied in many fields widely.This article applies the VR-GIS technology to the route selection of the high voltage transmission line based on some Remote sensing and GIS professional softwares,such as ERDAS,ArcGIS,MapGIS,etc,and makes the three-dimension sight flight system of the the 500kv transmission line hallway stri Pfrom Kangding to Chongzhou(segment from Dagang to Shaping).This method can reappears real terrain and relief of the studied area and involves worker...
