Data fusion for dissemination: web applications for the visualization of monitoring data

A monitoring system with an integrated web platform that has been installed to control the deformations of a road tunnel that intersects a block slide is presented. The system has been implemented in order to be redundant, scalable and providing the possibility to integrate different types of sensors. In fact, due to the importance of the monitored infrastructure the system needed to be extremely robust and reliable. The web platform has been designed focusing on the usability that is the ease of use and learnability. In fact, when monitoring a landslide or a structure, displacements are one of the main measured quantities. However, collected data are usually difficult to communicate with the classic displacements vs time graphs to local authorities and to the public. An automatically generated heat maps is available on the platform and the fact that the most active areas are identified with a reddish color while lesser movements are indicated in yellow uses a well-known communication code that helps understanding the dynamic of the process in a more intuitive way. On the other hand the possibility to have a single image available on the web to every person involved in the project helps the dissemination of results and confrontation creating an accessible common ground in the emergency phase.
