The SWSL @ retreat 2011 presentation summarized the Sensor Web, Web-based geoprocessing & Simulation Lab group. The group has 6 working members, 1 postdoc, and 10 assistants. Their research focuses on enabling live geoinformation through efficient origin, integration, and communication of sensor data. This includes work on sensor semantics, processing data streams, crowd-sourcing platforms, and approaches like a RESTful SOS proxy and ifgiCopter project. The group has ongoing collaborations and publications advancing work on live geoinformation systems.
