Devon,
Thanks for your help. The table is created for me by the plugin when I provide
configuration for my postgres datastore in datastore.properties. The create
table it issues ends up looking like this.
DEBUG [geotools.jdbc] - Create schema: CREATE TABLE "Temperature_surface" (
"fid" int AUTO_INCREMENT(1) PRIMARY KEY, "the_geom" BYTEA COMMENT 'POLYGON',
"location" VARCHAR(255), "imageindex" INTEGER, "time" TIMESTAMP )
I do have GEOTOOLS_DEVELOPER logging turned on but nothing jumps out at me why
the time column is not populated in the first place. I can see in the insert
statement it is passed as null but there is no mention as to why it is null.
After creating the store and layer, when I first try to preview the layer I get
an exception from the WMS server :
Unable to compute extrema value:TIME_DOMAIN_MINIMUM
which I assume is related to the time column being null.
When I populate the time column with a value, then there appears to be no data,
and blank tiles returning from the layer.
Thanks in advance for any help.
Steve

mosaic
Hi Steve,
I'm not an expert in serving GRIB in image mosaic, but would it be possible to
post your table schema? Possibly as a CREATE TABLE script for testing?
Also, trying to check off some of the obvious stuff, have you tried turning on
the GEOTOOLS_DEVELOPER logging profile and checking the logs?

Greetings,
I am attempting to make a time series using an image mosaic over data from
Nomads. The grib2 files I get from Nomads work perfectly as a grib2 data
source. However, when I attempt to create an image mosaic on top of the grib2
files all I end up with is blank tiles, and requests for data against the
exposed layer return no data, as though each point on the mosaic has no value.
I’ve created a datastore.properties, with valid postgres connection
information. I see the layer is represented in the postgres database, but a
couple of things are amiss. First the time column on the layer is null. Second
so is the imageindex column. The time column being null makes it impossible to
create a layer from the mosaic. If I populate the time column with a value I am
able to create a layer, but it is completely blank.
This is the grib file :
http://nomads.ncep.noaa.gov/cgi-bin/filter_hiresconus.pl?file=hiresw.t00z.arw_5km.f00.conus.grib2&lev_surface=on&var_TMP=on&leftlon=0&rightlon=360&toplat=90&bottomlat=-90&dir=%2Fhiresw.20160812

Any pointers would be greatly appreciated on how to get this grib2 data
functioning properly as an image mosaic. Many thanks!
