Ben, FYI, we did not have a WCS teleconference yesterday, having decided to skip this week during the teleconference on June 25. The WCS 1.2 SWG plans to meet again by teleconference on Wednesday, July 9. This teleconference will review the current discussion of CRSs in WCS 1.1 Corrigendum 2 (1.1.2), to suggest where clearer or additional information is desirable in WCS 1.2. The current discussion of CRSs in WCS 1.1 Corrigendum 2 is in Subclauses 7.5 and 7.6 of OGC 07-067r5, publicly available at http://portal.opengeospatial.org/files/?artifact_id=3D27297 I hope we will continue a vigorous dialog between GALEON and the WCS.SWG.

From: Ben Domenico Sent: Tuesday, July 01, 2008 10:39 AM To: wcs-1.2.swg@xxxxxxxxxxxxxxxxxxxxxxxx; Unidata GALEON Subject: [WCS-1.2.swg] GALEON WCS update Hi all, It appears that another conflict has arisen that will prevent me from participating in the WCS.SWG telecon tomorrow, so I'm using this email for a few updates on issues of interest to both groups. -- In GALEON phase 1, there was a very simple WCS use case, namely, the client specifies a "parameter" name, a bounding box, and time constraint and gets back a binary "coverage" that, if written to disk, is actually a CF-netCDF3 file containing the requested data subset. Perhaps I am wrong, but I thought the simplicity of that use case was one of the main reasons for the wide, active, and productive participation in GALEON 1. To my way of thinking, this use case represents the real core of WCS for our community. Efforts have been undertaken by Dominic Lowe and Steven Keens to make sure this use case is still covered in subsequent versions of WCS. -- The CF-netCDF3 encoding format specification has evolved from a brief document consisting mainly of pointers to information about the netCDF and CF conventions into an extension standard which is a complete specification of the WCS interface behaviors in cases where the delivery payload is CF-netCDF3. As a consequence, it's taking longer than anticipated to complete the first draft which is now anticipated to be available in mid-July. -- The current version of the CF-netCDF3 is now beyond my level of expertise, so Stefano Nativi is taking on the role of editor which reflects the fact that he is in fact doing most of the "heavy lifting" on this document. Our thanks to Stefano. If at all possible, I'll try to participate in at least part of the WCS.SWG telecon tomorrow. In any case though, it is important for us to continue a vigorous dialog between GALEON and the WCS.SWG. -- Ben
