OIIP: Oceanographic In-situ data Interoperability Project
"Leveraging available technologies for improved interoperability and visualization of remote sensing & in-situ oceanographic data at PO.DAAC"
The Oceanographic In-situ data Interoperability Project (OIIP) is a two-year technology development project initiated in September 2016 and funded under NASA's Advancing Collaborative Connections for Earth System Science (ACCESS) Program. This collaborative project aims to leverage and extend as necessary a set of available, higher TRL (Technology Readiness Level) informatics technologies for the improved integration of oceanographic in-situ and satellite datasets. The earth science enterprise increasingly relies on the integration of multivariate data from diverse observational platforms to enable research, mission calibration/validation, and decision support. The project seeks to enhance technical capacity in support of this broader objective by developing tools and approaches addressing key interoperability issues that are particularly acute for field campaign data sets.
The project is a collaborative venture between the Jet Propulsion Laboratory (JPL), UCAR/Unidata, and the Large Pelagics Research Center (LPRC) at the University of Massachusetts, Boston. Members of the project team include: V. Tsontos (PI) and co-investigators C. Thompson, N. Quach (JPL), C. Lam (UMASS/LPRC) and S. Arms (UCAR/Unidata), and JPL developers F. Platt and J. Roberts. OIIP also acknowledges the involvement and support of our external project collaborators Wildlife Computers.
Overarching goals of the project include:
- Enhance available earth science data technologies to address key interoperability and data challenges associated with oceanographic in-situ datasets, focusing on marine animal electronic tagging data as a representative (but also more challenging) use case. OIIP technology components include: the NCEI/NODC netCDF templates, Unidata's ROSETTAand THREDDS software, JPL's Common Mapping Client (CMC) and Data management & Archive System (DMAS) technologies, and the Tagbase relational database system (LPRC).
- Develop improved PO.DAAC capacity to support NASA field campaign data via the integration of these technology components within system workflows with a view to operational DAAC infusion
- Illustrate the value-added of satellite-in situ/tag data integration via an enhanced Web-based visualization tool
- Open Source release of software components for use by the broader earth data informatics community upon the conclusion of the project
Technology Enhancement & Integration
Extensions to the software technology stack leveraged by the OIIP project are summarized below. Additional tasks will include the integration of these in a test-DMAS environment to demonstrate data processing workflows end-to-end. It is important to note that while electronic tagging datasets serve as a thematic focus for OIIP, all capabilities will also be tested against more "conventional" in-situ data holdings available at the PO.DAAC, such as the SPURS field campaign datasets.
|NCEI/NODC .nc templates||
NCEI/NODC netCDF "spatial feature class" templates (8) are an implementation of CF/ACCD standards for the representation of discrete sampling geometry (point, profile, trajectory, time series etc.) data within the netCDF self-describing file format.
OIIP will review the adequacy of the templates for a range of tagging datasets while additionally provide implementation recommendations regarding representation of Domain specific metadata, Geolocation uncertainty, Data summaries.
Unidata's ROSETTA tool is a generalized web-based capability for conversion of unstructured columnar ASCII data files to CF/ACDD compliant netCDF files. It's GUI wizard provides a guided, step-wise process for conversion and augmentation of file metadata by user.
OIIP will: extend ROSETTA to support the NODC .nc templates and community specific metadata framework, and implement a RESTful web service automation interface. Integration of ROSETTA with PO.DAAC DMAS will also be pursued.
Unidata's "Thematic Real-time Environmental Distributed Data Services" (THREDDS) Web server technology provides metadata and data access for scientific datasets using a variety of remote HTTP-based data access protocols.
Extensions undertaken as part of OIIP will include support for point, profile, trajectory spatial data types, plus integration of the nc-SOS (OGC Sensor Observation Service standard) plug-in.
|CMC Web Visualization||
JPL's Common Mapping Client (CMC) is a software framework and reusable set of components for efficiently developing and deploying Web-based mapping applications for the exposure of earth science data.
During OIIP, CMC capabilities will be extended to access, integrate and display in-situ and satellite-derived datasets, providing synchronized horizontal and vertical profile views of data and their evolution over time.
The Data management & Archive System (DMAS) is an integrated set of software components that comprise JPL PO.DAAC's data archival and distribution architecture.
Work on DMAS undertaken as part of OIIP will focus on extensions to the DMAS internal metadata model for comprehensive CF/ACDD/NODC support, data handler extensions, Rosetta RESTful-Web Service development and Rabbit-MQ middleware enhancement.
Tagbase is a relational database system for the management of (non-acoustic) electronic tagging datasets developed to assist smaller research groups to manage their data collections. While being simple to use, it provides a comprehensive data model and multi-tag, multi-manufacturer support.
During OIIP, Tagbase will be ported to the PostgreSQL open source RDMS, and its stored query procedures will support the CMC-Visualization tool on the backend.
The approach to project implementation is best encapsulated as "Community, Data Technologies, Standards, Team". OIIP places particular emphasis on community engagement and community driven approaches. We see this as critical to robust use case and requirements development. Collaboration and coordination with stakeholders is deemed essential for buy-in on technology and standards development aspects. Stakeholders with whom we are in communication include NCEI/NODC, IOOS-ATN, SPURS, PODAAC, ESDWG Data Interoperability Working Group, CF2. Additionally, OIIP has partnered and is working closely with a leading e-tag instrument manufacturer (Wildlife Computers) with the aim of ultimately implementing interoperable file/metadata standards recommendations sustainably at source.
