|Conventional monitoring of physical spaces uses manual sample collection to build coarse-grained spatiotemporal models of monitored phenomena. With the increased availability and affordability of low power sensors, using data from these sensors to validate and evolve existing models presents both a challenge and an opportunity. Conventional methods have undergone long-term testing yet they only provide coarse-grained information, while low power sensor networks are relatively new yet provide high resolution spatial and temporal data. The DSS Group is working on new methods for fusing the different data sources from sensor networks and conventional methods for more reliable and representative spatiotemporal models of the underlying environment. We have already applied this capability to the problem of mine rehabilitation, where mining companies must maintain a lease on the mine site until they can show they have restored the ecosystem to its original state.|
