With a time-enabled image mosaic as the data store, is there an easy way to get multiple return values for time series raster data via GetFeatureInfo (or anything else available on GeoServer)?
For instance, in one request I would like to get all values for a grid cell for all times available in the mosaic. So, say I have hourly rasters covering a 24 hour period, I would like to return the 24 hourly values at a particular lat/lon in a single request.
Thanks,
Mike Grogan
Hi Mike,
I had exactly the same problem. I solved it using the multidimensional
outputformat support in the geoserver WCS implementation. I wrote a custom
multidimensional outputformat encoder, which encodes to json. Then I send WCS
GetCoverage requests to geoserver, using something like 'custom/json' as the
outputformat.
My outputformat code then receives a 'GranuleStack', which I encode to json.
If you're interested in this approach, I can lookup some code pointers and
possible workarounds that were needed to get this to work.
best regards,
Jeroen

I guess this could be of general interest too. Have you considered
contributing
it to the community? (just wondering)

There is no way as far as I know, the code in GetFeatureInfo raster data
handler would have to be modified to handle this use case

Hi Andrea,
yes I have, only problem is, in what form? The code itself is relatively
small, undocumented and untested, and I'd rather not put something like that
online with my name on it ;-).
Another option is perhaps to describe my approach in some kind of small guide
or article. I particularly like it because it uses the somewhat
underappreciated WCS implementation.
Anyway, when I find some time, I'll see what I can do.
best regards,
Jeroen
