Computing happens somewhere
Matt Duckham


Geographic information has traditionally been stored and processed in physical locations that are unrelated to the actual locations referred to in that information. However, spatial data capture and computing devices are increasingly embedded in geographic space. Technologies like geosensor networks, for example, can be embedded in built and natural environments to capture, compute with, and communicate dynamic geographic information. The challenge is to equip these embedded technologies with the capability to respond directly, in the network, to spatiotemporal queries about the rapidly changing environment. Building on specific examples of emerging environmental monitoring applications, this talk examines some of the key algorithms and computational principles behind information systems for "computing somewhere."
