1. An OGC Interoperability for Ocean Science Gerald Creager Texas A&M University Luis Bermudez Southeastern Universities Research Association Philip Bogden SURA Coastal Ocean Observing and Prediction Program

2. Ocean Science Interoperability Experiment Open Geospatial Consortium, Inc.

3. OGC OCEANS IE Approved December 2006 by OGC Initiated March 2007 Evaluate and compare SWE/SOS/TML and WFS specifications for efficacy in distributing sensor data Provide example code and cookbooks to assist new implementers Built on the experience/expertise already derived in OOSTethys  Allowed “quick-start” of the project

4. OGC OCEANS IE Key Participants  SCOOP Texas A&M, GoMOOS, VIMS, SURA/SCOOP  NANOOS (Bill Howe)‏  AOOS (Rob Cermak)‏  MBARI (John Graybeal)‏  UNH COOA (Ru Morrison)‏  WHOI MVCO (Janet Fredricks)‏

6. OGC OCEANS IE Plan  Develop several SOS services acceptable sensor descriptions/schemas support measurements of  Salinity  Temperature  Others (as we determine what they are)‏  Servers... and Clients Document development Provide data to potential developers

7. OGC OCEANS IE Data are accessible as graphical objects on a map  http://www.openioos.org/testbed/sos/gm_sos.html  http://www.openioos.org/testbed/sos/ Data are accessible as text/table Data are available as time-series presentations

12. OGC OCEANS IE Observations Query Support WFS  Version 1.1  Bounding Box: getFeature  lat long; lat lon z  Procedure (requires workaround)‏  Observed Property (requires workaround)‏ SOS  Version 1.0  getObservation  lat lon; lat lon z  time instance/interval  time interval min only  time interval max only  Procedure and Obs. Property supported  http post required

13. OGC OCEANS IE WFS requires schema creation/definition  Maintenance, versioning, extensibility, standardization SOS requires adoption of a set of specifications  time/learning curve to understand specifications/standards

14. OGC OCEANS IE End products  Roadmap/procedures to implement specs used (SOS, WFS)‏  Prototype servers and clients developed Code available Reference implementations  Cookbooks for developers Feedback results to OGC for specifcation update/improvement

15. OGC OCEANS IE Lessons learned  Adopting standards is hard  Need to involve science domain expertise  Beats reinventing the wheel  Long-term payback potential is better than “one- off’s”  Use of standards promotes innovation
