Automatic generation of an interactive, real time, web-based maps from sensor-based geographic databases

Abstract

In recent years, we have seen a growing number of location-based sensors used to measure increasingly diverse phenomena. Therefore, we consider the increasing need to efficiently manage the huge amount of data collected from located wireless sensor networks (WSN). In some phenomena, it is fundamental to generate maps in real time. Data can be grouped into web-cartography for diverse purposes; so finally, we develop a web-based mapping on demand. In this paper, in addition to cartographic functionalities mentioned above, we are facing another challenge. Indeed, we encounter the problem of avoiding on-the-fly overlays of multiple visual layers in order to get a result that is easy to interpret due to visual interference between graphic elements. The present paper describes an approach to the cartographic visualization of geo-data regularly acquired by WSN and exhibits a prototype portal based on an open source platform for integrated visualization as visual realtime summaries. An application in meteorology is proposed.
