A Comparative Study of 3D Web Integration Models for the Sensor Web

Abstract

To facilitate the dynamic exploration of the Sensor Web and to allow users seamlessly to focus on a particular sensor system from a set of registered sensor networks deployed across the globe, interactive 3D graphics on the Web, which enables sensor data exploration featuring a good level of detail for a multi-scaled Sensor Web, is necessary. A comparative study of decent approaches to integrate Sensor Web information with the latest 3D Web technology and the geospatial Web has been conducted. We implemented prototype systems in three different 3D Web integration models, i.e., a common X3D model, the X3DOM integration model, and a webized AR content model. This paper presents examples of our prototype implementations using various approaches and discusses the lessons learned.
