3. Ocean.US Created by the National Oceanographic Partnership Program to implement the sustainable Integrated Ocean Observation System (IOOS)

4. Ocean.US IOOS Goals Detecting and forecasting oceanic components of climate variability Facilitating safe and efficient marine operations Ensuring national security Managing resources for sustainable use Preserving and restoring healthy marine ecosystems Mitigating natural hazards Ensuring public health

5. Open GIS Consortium What is the Open GIS Consortium? The Open GIS Consortium, Inc. (OGC) is a non-profit industry consortium aimed at growing interoperability for technologies involving spatial information and location. OGC delivers open standards specifications for the GIS industry to follow.

6. IOOS Sea Surface Temperature Pilot Project IOOS SST Distributed Data IOOS is envisioned as an integrated system of measurements (monitoring), data management, and analyses The problem: Integrating data from various locations in various formats from various data providers A candidate solution using SST*: Participating SST Data providers expose data as OGC standards-compliant Web Map Services (WMS). This data can be accessed via WMS enabled portal. * Proposed by NOAA Coastal Services Center and Navy Office of Naval Research

7. Data Delivery in IOOS SST What are Web Map Services? Web Map Services (WMS) are an XML standard defined by the Open GIS Consortium (OGC) Web Map Services respond to three types of URL requests with request-appropriate data –GetMap: returns a map –GetFeatureInfo: returns data relevant to the selected feature –GetCapabilities: returns an SML file with capabilities for the specified Web Map Service

8. Data Delivery in IOOS SST How Do Web Map Services Work? Web Map Service applications request data from multiple data providers Data providers reply with appropriate response based on request Web Client Web Server 1 Web Server 2 Web Server 3 Coastline DB Buoy #45 DB States DB Web Server X Buoy #X DB

9. Data Delivery in IOOS SST How Do Web Map Services Work? Web Map Service applications request data from multiple data providers Data providers reply with appropriate response based on request – in this case, a map of buoys

10. Data Delivery in IOOS SST How Do Web Map Services Work? With distributed data we need to control the display of like features coming from different sources Display rendering can be controlled by a centralized Style Layer Descriptor (SLD) file, which is similar to Cascading Style Sheets for HTML SLD files are used to query for time slices

11. Data Delivery in IOOS SST WMS Is Not the Only Answer Since WMS requests a new image from each server for every map request, it is not the fastest bike on the block Web Feature Services (WFS) appear to be the next generation of open standards distributed mapping

12. Data Delivery in IOOS SST Web Feature Services — The Next Frontier WFS passes vector-based data back to the client, which can be displayed as it is received and cached for future use WFS is another OGC specification

13. Data Delivery in IOOS SST Open Standards Are the Key to Success The IOOS SST Pilot Project depends on OGC-compliant data providers Participating partners must expose their data in an OGC- compliant format (WMS or WFS) ESRI and Minnesota MapServer currently offer OGC- compliant data publishing options

14. Data Quality Control in IOOS SST Data Quality Standards Are Still in Development Data providers all have different methods of quality control Ocean.US as a governing body will need to enforce standards as IOOS evolves National Buoy Data Center has been researching and holding conferences on buoy data quality control
