Dear Simone,
Thank you for your reply to my questions.
Let me try to explain in more detail and the use case, I'm starting with
my second question because that is the most important one:
2. I am using GeoServer to present weather data in a mobile application
for pilots. Since the pilots will be using the app in the air without
internet connection it is important to make the map data available
offline, by caching. In the app it is possible to request layers in the
future as some are forecast maps, in 3 hour intervals. However, if a
layer is not available yet for the time requested, I do not want a blank
image to be returned because then that blank tile will be cached and
would not refresh when the layer for the that same time becomes
available on the server. I also don't want the closest available time
to be returned for the same reason. Therefore I would like to know if
the layer is available for the requested time or not.So in the below
example, if I request any time not listed in the time extent, I would
want an exception returned. Is that possible?
Of course I could do that with a GetCapabilities request ahead of the
GetMap request, but already now I sometimes get an exception (granule
cannot be found) and sometimes not when I request an image for a time
that is not available. That's what I am trying to figure out, why it's
only sometimes an error and if it's possible to always get an error
returned when the time is not available. The mosaic data is saved in
Postgres and I am using version 2.18.2 (of course not 1.18.2 as I wrote
initially)
1. Now for the first problem, the missing layer in GetCapabilities.
Thank you for pointing me in the right direction. I am indeed seeing an
error in the log when doing GetCapabilities. See below screenshot and
log. (The default value always displays "Choose one" regardless of what
I have saved previously).
Thanks and best regards
Niklas

Hi!
Sorry for another question but I'm not having any luck with
finding the
answer to this.
I have 2 issues that might or might not be related, no idea really.
1. A newly created ImageMosaic layer with TIME dimension (List) is
not
returned in the XML when requesting GetCapabilities. Doing GetMap
requests with the times for which images are available works fine, no
problem, it's just not shown in the capabilities XML. I have three
other
layers from other stores that ARE shown in the XML.
We need more info to be able to help.
What do you mean by "Doing GetMap
requests with the times for which images are available works fine, no
problem"?
Do you see any errors in the log when you issue a GetCap? You can make
a single layer GetCap by adding /workspace/layer before ows to isolate.
Can you share a screenshot of the Dimensions tab content?
2. All my layers have TIME dimension. I might have misunderstood
the WMS
specification but I am under the impression that if I make a GetMap
request for a specific time that does not exist in the published
layer,
the server should return an exception. (E.g. images exist for the
year
2021 and if I make a request for a time in 2020 it should return an
exception). My problem is that yes it does return an exception,
sometimes.... Sometimes it returns just an empty png and it seems
completely random. I do not have "Nearest match" enabled. I need
to have
an exception returned if the user requested time does not have a
corresponding image that exactly matches the time.
Any recommendations/workarounds how to solve especially the second
issue?
I'm running version 1.18.2 and the ImageMosaic information is
stored in
Postgres.
I do not remember what the WMS spec says but GeoServer by default
returns a blank Image if your request falls in the right bbox but does
not meet any WMS dimension.
If you activate the Nearest Match it broadens the search period time.
I kind of remember that we added the possibility to return an
exception when no TIME match is found but I can't find the issue now.
Maybe @Andrea Aime
<mailto:andrea.a...@geosolutionsgroup.com> remember about this?
Thanks in advance for any assistance provided.
