Devon, I must be missing something. This is what I tried.
I downloaded todays build of Geoserver, the Grib, NETCDF, and image-mosaic plugins. I installed the plugin jars to webapp/geoserver/WEB-INF/lib. I confirmed my geoserver is running the new version : Build Information · GeoServer Version2.10-SNAPSHOT · Git Revisione33ceabf81b7a225db263dede3ea6a567aa6d240 · Build Date15-Aug-2016 08:01 · GeoTools Version16-SNAPSHOT (rev 12844adebde2e5820f7f97f21c2dbd5b95f087f8) · GeoWebCache Version1.10-SNAPSHOT (rev 8ee448d1b6766c6577bca25084496debb50271e5/8ee448d1b6766c6577bca25084496debb50271e5) I downloaded the latest GRIB file via 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.20160815 I added a Raster Data Source of Type ImageMosaic and selected the directory where the above file was saved. In that directory I had 3 files, indexer.xml _auxiliary.xml datastore.properties all here at this gist : https://gist.github.com/anonymous/8648c5e81d981c43095663108e5095e1 I publish the layer Temperature_surface enabling the time dimension. Presentation List, Use smallest domain value. When I preview the layer, the WMS service raises the exception : java.lang.IllegalStateException: Unable to compute extrema value:TIME_DOMAIN_MINIMUM Unable to compute extrema value:TIME_DOMAIN_MINIMUM How does this differ if at all from what you tried? Thanks!

I didn't use PostGIS, since I don't have time to add a custom projection right now (I assume you have a custom projection added), but I did try to add it to PostGIS to see what the results would be on the insert and it seems that Time does get correctly added: 15 Aug 13:32:08 DEBUG [geotools.jdbc] - Inserting new feature: INSERT INTO "public"."Temperature_surface" ( "the_geom","location","imageindex","time" ) VALUES ( ST_GeomFromText('POLYGON ((-4228647.898383763 -835237.3149693012, -4228647.898383763 4370737.742215395, 3252718.9433056377 4370737.742215395, 3252718.9433056377 -835237.3149693012, -4228647.898383763 -835237.3149693012))', 999004),'/Users/devon/Data/grib-postgres/hiresw.t00z.arw_5km.f00.conus.grib2',0,'2016-08-11 17:00:00.0') I did get it rendering using the H2 data store however: (Looks kind of ugly cause I didn't bother changing the style) A couple questions: - Did you make sure to enable the time dimension in the layer publishing config? - Which versions of GeoTools/GeoServer are you running? I'm only testing against master right now, I can maybe check it out in older versions later when I have more time. I know Ben has fixed some bugs in this area lately. Here are the configs I used: https://gist.github.com/dvntucker/9824309a09a86a28f76e9d6ef117221f Cheers Devon Tucker Software Engineer Boundless Spatial On Mon, Aug 15, 2016 at 11:23 AM, Ferguson, Steve -FS <sfergu...@fs.fed.us<mailto:sfergu...@fs.fed.us>> wrote: 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.

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?

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 This is my indexer.xml <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <Indexer> <domains> <domain name="time"> <attributes><attribute>time</attribute></attributes> </domain> </domains> <coverages> <coverage> <schema name="Temperature_surface"> <attributes>the_geom:Polygon,location:String,imageindex:Integer,time:java.util.Date</attributes> </schema> <domains> <domain ref="time" /> </domains> <origName>Temperature_surface</origName> <name>Temperature_surface</name> </coverage> </coverages> <parameters> <parameter name="AuxiliaryFile" value="/gdata/grib/nomads_img/_auxiliary.xml" /> <parameter name="AbsolutePath" value="true" /> </parameters> </Indexer> This is my _auxiliary.xml <?xml version="1.0" encoding="UTF-8"?><Indexer> <coverages> <coverage> <schema name="Temperature_surface"> <attributes>the_geom:Polygon,location:String,imageindex:Integer,time:java.util.Date</attributes> </schema> <origName>Temperature_surface</origName> <name>Temperature_surface</name> </coverage> </coverages> </Indexer> Any pointers would be greatly appreciated on how to get this grib2 data functioning properly as an image mosaic.
