Hi all,
I'm working on exposing a single EO dataset in geoserver through the WCS-EO
and WMS-EO services. The dataset consists of multiple bands, but they are
exposed through a custom dimension of the underlying image mosaic.
This works very well for WMS-EO, but doesn't seem to work for WCS.
Does know how such a setup can be made to work? The underlying image format is
NetCDF4, so the bands in the data are in fact separate netcdf variables.
thanks,
Jeroen

Not sure... in our case we prepare the data and have different versions of
it published
as WMS-EO, and as WCS, because as you said the needs of the two protocols
are different.
I guess it would be interesting if the bands dimension was active only when
certain request
params are used, or something like that.

Hi,

Is there any guidance to be found on how to prepare a netcdf dataset
consisting of multiple files so that the variables in those files show up as
bands of a single coverage? (To support WCS)
I guess it would be interesting if the bands dimension was active only when
certain request
params are used, or something like that.
I may be able to do that already, but even then I still need to somehow expose
multiple bands in my mosaic.
Cheers

We implemented this by transforming the original files to geoTiff multiband files.
This was the most performant way for displaying large coverage files and accessing them.
For the rest we found no specific userguide to help us.

Hi,
thanks for the suggestion, but in this specific project we would like to avoid
copying the entire dataset. We try to achieve performance by using
geowebcache.
However, the fact that WMS-EO can use jai to combine multiple granules into a
single image, seems to suggest that exactly the same thing should be possible
for WCS, but it just isn't implemented right now.
Is anyone else interested in this kind of implementation, which would enable
the use of the same data source for both WMS and WCS?
thanks,
Jeroen
