The file contains time stamp over a period of 48 hours. I fallowed your advice
and deleted the TimestampFileNameExtractorSPI and the configuration of the
coveragestore worked fine. But I still have to enable time dimension in order
to see the raster in layer preview. Without enabling time dimension, the image
was displayed a bit wired, a narrow polygon. Any idea how I could enable time
through the REST API?
Kind regards,Corina

Hi Corina,A couple of questions to better understand your use case:
Do your sample NetCDF Files internally exposes a time dimension with multiple
values as per the example below OR does it contain no time at all and the only
reference time is on the filename itself, instead?
Example:float time(time=24); :units = "hours since 2013-03-03 0:00:00"; data:
{0.0, 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0, 10.0, 11.0, 12.0, 13.0,
14.0, 15.0, 16.0, 17.0, 18.0, 19.0, 20.0, 21.0, 22.0, 23.0}
If that is the case (time dimension available and multiple values), imageMosaic
and underlying NetCDF reader will parse and expose time dimension/values with
no need to define a TimestampFileNameExtractorSPI in your indexer.
If, conversely, your data has no native time dimension you may need to define a
TimestampFileNameExtractorSPI and related regex too to extract the time from
the filename.Something like:[0-9]{8}T[0-9]{4}
In addition, if your data actually has a native time dimension and different
files have an overlapping time instant due to the 48hours time period, you may
need to define a runtime additional time dimension using the Timestamp
extractor again.
Please, let us know.
Cheers,Daniele

Hi list,
I am trying to add a netcdf file with a more complex structure than the
polyphemus file that it's used in the tutorials. I am having issues passing
the time dimension. I am able to create the database though.
I have also read this thread
http://osgeo-org.1560.x6. nabble.com/ImageMosaic- indexer-xml-time-domain-
custom-dimensions-td5144486. html
, but I do not completely understand how to pass the time.
The file is: 20180218T1200Z_tropical_africa
On this line <value>[0-9]{8}</value> I don't quite understand what values
should I pass considering that my date and time is this 20180218T1200Z and
the data inside the netcdf is covering 48 hours.
Any help is much appreciated.
Best regards,
Corina
