The Coastal and Marine Geology Oceanographic Model and Time Series Portal

Presentation to the USGS Coastal and Marine Program leaders in Woods Hole, 10/23/2015

Transcript

1. The Coastal and Marine Geology Model and Time Series Portal A portal built on a standards-based framework for oceanographic data 2015-10-06
2. The Fourth Network Layer: Data • “We need an end-to-end, layer-by-layer, designed information technology … that are composed of no more than a stack of protocols” • “We need open standards… and above all, we need to teach scientists to work in this new layer of data” 2 From the essay: “I have seen the Paradigm Shift, and It Is Us”, byJohn Wilbanks, in the book “The Fourth Paradigm” Data Web TCP/IP Ethernet
3. US Integrated Ocean Observing System (IOOS® ) IOOS® Plan defines: • Global Component • Coastal Component  17 Federal Agencies  11 Regional Associations
4. IOOS Core Principles • Adopt open standards & practices • Avoid customer-specific stovepipes • Standardized access services implemented at data providers 4 Customer Web access service Data Provider Observations Models
5. Ocean grids are often not regularly spaced! Stretched surface and terrain following vertical coordinates Curvilinear orthogonal horizontal coordinates
6. Unstructured (e.g. triangular) grid

9. Interoperable access in Matlab (nctoolbox)
10. Interoperable Access in Python (Iris)
11. Catalog Search 11
12. Catalog Search 12 Catalog services can be federated via OGC CSW (Catalog Service for the Web)
13. IOOS System Test
14. Building the CMG Model and Data Portal • Sparked by Sandy funding (Warner & Ganju) • Goal: A single portal for discovering and viewing distributed data across CMG • Our model output was already available via standard services supported by IOOS • Leverage IOOS-funded portal-building infrastructure • Collaborative between CIDA and IOOS developers (Axiom Data Science) 14
26. CMG Model and Time Series Portal
27. The Future • Add functionality based on user feedback • Maintain the portals • Bring in St. Pete and Santa Cruz datasets • Work toward a open-source portal infrastructure for the entire geospatial community • Metanomy.org example 27
28. Open source innovation 28
