Usual story - really want this, but no effort to put in... :-( > Is there a UI config for the new WCS stuff? If not, what > needs to be done? If you stick with a small subset (perhaps one) of netCDF conventions you can imagine a netCDF collection 'scanner' that picks out e.g. spatiotemporal metadata defined by those conventions across the fileset, and presents additional configurable options in a GUI. We're working on this in NERC DataGrid for CSML - rather than geoserver config - generation. > In general - we have two requirements in the medium term: > 1) auto-configure WCS for a catalogue of NetCDF files, to > support subsetting actions easily having found a netCDF file > in a catalogue In most atmos/ocean use cases you don't want file-level discovery.

The 'CF' conventions for atmos/ocean data are the canonical standard: http://www.cgd.ucar.edu/cms/eaton/cf-metadata/CF-1.0.html though (as far as I'm aware) not implemented in full *anywhere*. However, an incremental approach can be taken - e.g. starting with independent spatiotemporal coord vbls (http://www.cgd.ucar.edu/cms/eaton/cf-metadata/CF-1.0.html#grid_ex1), then sorting 'auxiliary coord vbls' (http://www.cgd.ucar.edu/cms/eaton/cf-metadata/CF-1.0.html#grid_ex2) etc... A large amount of deployed met/ocean netCDF is covered by a small subset of CF. ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
