Virtual reality based novel use case in remote sensing and GIS

Abstract

Virtual reality (VR) is realistic, interactive and immersive 3D computer generated world that one can explore as if one is present in the scene. VR makes it possible to experience anything, anywhere and anytime. Head mount device (HMD) with headphones and hand controllers are used to provide fully immersive experience. There are three important I’s in VR; interactivity, immersion and imagination. Virtual reality is stepping in each and every domain like engineering, science, military, education, medical, tourism and entertainment. We have explored its potential for usage in remote sensing and Geographical Information System (GIS). Usually, GIS users analyse remote sensing data such as high resolution images, digital elevation models and vector data in commercial and open sources 2D GIS software(s). Available GIS software(s) allow users to interact with remote sensing data as a third person only. We have developed in-house virtual reality solution to generate a 3D terrain using high resolution imagery and elevation models over Earth. User can move around or teleport to different locations inside the 3D scene and interact with real time objects available in the scene.
