These are a few of the highlights of last week's OGC (Open Geospatial Consortium) Technical Committee (TC) meetings -- from our perspective.
-- The meteorology community (including liaisons with the WMO and NOAA) are participating in an increasingly active role in the OGC TC. This marked the second meeting of the Meteorology Domain Working Group (DWG now co-chaired by Chris Little of the UK Met Office and Marie Francoise Voidrot of Meteo France). The primary technological focus still seems to be on WMS, but there were increasing calls for expanding that in the future. The meeting agenda and presentations are available at:

One other item of note is that some members of the Met DWG, including me, think it should include Oceanography as well, but that decision was put off until the next TC meeting. So we continue with separate Hydrology and Met working groups and the Earth System Science (ESS) DWG as a group where integrated cross-disciplinary issues can be addressed. Efforts are made to avoid scheduling conflicts among these groups.
Issues relating to Coordinate Reference Systems (CRS) came up in the WCS Standard Working Group (SWG) session as well as in the CRS DWG meetings. For our community an interesting aspect of this are discussions of "image" CRSs. In essence, an image CRS is index-based which, to my way of thinking, has some strong conceptual similarities to the way we work with coordinate system information in netCDF and OPeNDAP. And, as with our work, the challenge is to come up with a formal description of how the index space relates to other index spaces or (heaven forfend) the real world.
