Hi,

Time dimension at least in image mosaics is not quite similar than for example 
spatial dimensions because it is not really continuous and it usually does not 
make sense for example to interpolate values from orthophotos which are 
acquired in different years. See an excerpt from DescribeCoverage

<wcsgs:TimeDomain default="2017-01-01T00:00:00.000Z">
<gml:TimeInstant gml:id="ortotesti__ortokuva_td_0">
<gml:timePosition>1985-01-01T00:00:00.000Z</gml:timePosition>
</gml:TimeInstant>
<gml:TimeInstant gml:id="ortotesti__ortokuva_td_1">
<gml:timePosition>1986-01-01T00:00:00.000Z</gml:timePosition>
</gml:TimeInstant><gml:TimeInstant gml:id="ortotesti__ortokuva_td_2">
<gml:timePosition>1988-01-01T00:00:00.000Z</gml:timePosition>
</gml:TimeInstant>

We have been thinking what should happen with an orthophoto coverage if WCS 
user is asking for a time range that does not include any TimeInstant, or if 
range covers many TimeInstants. The latest TimeInstant within the range, or the 
closest one in the past if nothing is found otherwise might suit for us. For 
some other kind of coverages like meteorological data that is not good approach 
but users probably want to get strictly what they ask as multilayer netCDF file 
or animated GIF or whatever.

time dimension

Hi Jukka,
the proposal is targeted solely at WMS, but the code is being setup so that the 
same facilities
can be reused for WCS as well, in case someone wants to.
I'm not sure WCS has any way to advertise such support, and time is just 
another dimension there,
e.g., is it treated the same as spatial ones.

Cheers
Andrea

Will it work also with WCS 2.x for time positions and ranges?

Hi,
the mailing list issues caused some delays, a few people already cast their 
vote directly
on the GSIP and notified on gitter.

Hopefully the list is back in working state, keep the feedback/votes coming :)

Cheers
Andrea

Hi,
as briefly suggested during a recent GSIP meeting, here is the proposal for 
adding WMS nearest match support on time dimension:

https://github.com/geoserver/geoserver/wiki/GSIP-166

The proposal is limited to time due to resource limitations, but care will be 
taken not prevent/complicate future support
for elevation and custom dimensions.
The proposal is currently scheduled for 2.14.x, although a request for backport 
might happen at a later date.

Please discuss, or if you're happy with the proposal as is, cast a vote :-)

Cheers
Andrea
