IP cameras (the new technological standard in video surveillance, with increasing sensor quality and computational power) can autonomously and continuously shoot images to be processed for rain measurement, while smartphones, due to the lack of clear strategies to engage citizens in an active and enduring crowdsourcing of significant rainy images, resulted to be a less reliable source of precipitation data. Consequently, we decided to freeze the development of a dedicated Sentinel app, at least until we haven't identified a strategy, or a sustainable business model, to effectively engage citizens.
While characterizing the customer landscape, we concluded that the EU landscape of civil protection agencies is highly fragmented both in terms of authorities and territorial competences, and hence extremely difficult to penetrate in a profitable way. At the same time, we realized the importance of road networks in the context of civil protection, and turned our attention to their managers, to assess their monitoring and early warning activities. Road managers have their own interest in rain monitoring (they must ensure drivers safety) and usually already have camera networks which may be enhanced for rain gauging. Furthermore, roads usually extend over large distances, thus representing ideal transects for monitoring precipitations over large territories. Then rain data collected along the roads may be shared with environmental and civil protection agencies or sold to private subjects such as weather forecasters, with a positive return not only for people on the move, but for everyone.
