Hi everyone,
I have a problem when applying temporal subsetting/trimming (WCS,
/GetCoverage/) to a layer of an image mosaic which was created from
netCDF files.
*Background**:*
Geoserver version: 2.18.3
Extensions: netcdf, netcdf-out
I created an image mosaic by adapting the configuration I found here:
https://github.com/GeoNode/geoserver-restconfig/blob/master/test/data/empty.zip
The index is stored in a PostgreSQL/PostGIS database.
For a start I added two granules, netCDF files consisting of two
variables for one day in 3-hour steps:
* global-analysis-forecast-wav-001-027_20220101.nc
* global-analysis-forecast-wav-001-027_20220102.nc
The creation was successful and I could create two layers from the
mosaic image store based on the two variables.
*The problem:*
I am able to use slice operations,
/&subset=time(%222022-01-01T09:00:00.0%22)/, in /GetCoverage/ requests
successfully. Trim operations,
/&subset=time(%222022-01-01T09:00:00.0%22,
%222022-01-01T15:00:00.0%22)/, do work as long as the time range is
within one file. If the time range is across files, e.g.
/&subset=time(%222022-01-01T21:00:00.0%22,
%222022-01-02T09:00:00.0%22)/, the data I get back for time steps
contained in the second file all equal to zero.
Is this a known problem? Any ideas what I might do wrong?
If you need more details about the configuration, let me know.
Best regards
Martin
