Subcommittee on Interoperability

Back to <Interoperability of Air Quality Data Systems

Following the group recommendation at the March 12 telecon, it was recommended that a subcommittee be formed on interoperability of data systems to address the diversity of interoperable data standards and to make recommendations. Several volunteers agreed to participate, including: David McCabe, Steve Young, Nick Mangus, Tim Dye, and Rudy Husar. The interested data systems should monitor the activities of the interoperability group. The initial activities of the group should include:

Identify interoperability standards and methods,
Test and apply these standards to several EPA data systems
Apply GEO principles and architecture and ESIP venues and community

Interoperability of Air Quality Data Systems Workspace

In order to facilitate the work of the Interoperability Subcommittee, a wiki workspace was set up on the topic of Interoperability of Data systems. This workspace is on the ESIP wiki and will be used to accommodate inter-agency and inter-disciplinary participation.

The primary recommended standard is the OGC Web Coverage Service (WCS) data access protocol.

Ideas on the structure and functionality of the workspace?

Description and Tutorial on the WCS Interoperability Standard

Here is a screencast on DataFed WCS (5 min WCS, 4 min DataFed app). Also , here is a paper on the topic, and the related PPT. To see WCS live, select a dataset from the DataFed catalog. and then click on the WCS button in the second column, say on the AirNow tabular data WCS link. In the Format field select CSV Table. Click on GetCoverage and a CSV table is returned ... Your browser may invoke Excel to show the table.

What other materials on interoperability should be collected?

Candidate Data Systems for WCS Interface

There are several data systems affiliated with EPA, which could be made interoperable using the WCS OGC Standard Protocol. <ask format="ul" limit="100" > +</ask>

The list of WCS-cadidate data systems should be discussed.
