Sensor Web Enablement
The OGC Sensor Web Enablement interoperability interfaces play a key role in many of the sensor web prototypes under development in NASA’s Advanced Information Systems technology (AIST) program, in the GEOSS pilots and other efforts.
This session will focus on the leading-edge experience of early adopters of the sensor tasking services such as the Sensor Planning Service and others. What are your experiences with early implementations?

The following listing tracks the discussion topic comments. Participants shared SWE lessons learned regarding complexity, performance, interoperability, overall satisfaction and notional total cost. We also discussed the NASA's rationale for and potential future interactions with SWE and OGC. A diagram exists at the TIWG sensor web collaboration web site.

SWE Lessons Learned Don S. [IKHANA] SPS Issues Where is the plan? What was tasked? Who tasked it? User Authentication Access Control Asynchrony & Notifications Specifications Interdependance SAS WNS What about CAP? SPS vs Workflows Meta-SPS Draper SEPS (Liping) JPL ASPEN/CASPER
Pat C. [EO-1] WFS SOAP API Old REST API SOS SAS/WNS -> OPS-B WfCS SPS Different Communities Big IT shops ESA NGA Big Tightly Coupled Enterprises Mass Market neo-geographers Value-added Providers
Liping D. [GeoBrain] SWE getting Complex (SesnroML) Specification Overlap SAS/WNS interoperability issues Metadata / semantic issues Catalog issues SWE still work in progress but very promising no WSDL for GEO applications
