Hi all,I've just downloaded the latest version of TDS and tried out WMS on some datasets. It looks like the TDS implementation of the WMS server is ignoring the _FillValue attribute...?
I've tried this on ncWMS-1.0RC2 and it was able to generate a correct image. I used the same KVP (except for LAYERS!) for both ncWMS and TDS: http://localhost:8080/ncWMS-1.0RC2/wms?LAYERS=bomTest%2Ftemp&ELEVATION=-5&TIME=2010-07-07T12%3A00%3A00.000Z&TRANSPARENT=true&STYLES=boxfill%2Frainbow&CRS=EPSG%3A4326&NUMCOLORBANDS=254&LOGSCALE=false&SERVICE=WMS&VERSION=1.3.0&REQUEST=GetMap&EXCEPTIONS=XML&FORMAT=image%2Fpng&BBOX=0,-90,180,90&WIDTH=256&HEIGHT=256 http://localhost:8080/thredds/wms/testAll/ocean_an_20100707_temp.nc?LAYERS=temp&ELEVATION=-5&TIME=2010-07-07T12%3A00%3A00.000Z&TRANSPARENT=true&STYLES=boxfill%2Frainbow&CRS=EPSG%3A4326&NUMCOLORBANDS=254&LOGSCALE=false&SERVICE=WMS&VERSION=1.3.0&REQUEST=GetMap&EXCEPTIONS=XML&FORMAT=image%2Fpng&BBOX=0,-90,180,90&WIDTH=256&HEIGHT=256And got the attached images (tds.png is generated from TDS, wms_ncwms.png is generated by ncWMS).
I am currently using: Version 4.2.20100607.1833 - 20100607.1833 With Java version: java version "1.6.0_20" Java(TM) SE Runtime Environment (build 1.6.0_20-b02-279-10M3065) Java HotSpot(TM) 64-Bit Server VM (build 16.3-b01-279, mixed mode)We had observe the same behaviour on another TDS server too, although, I'm not sure what OS it's running on, or what the version of Java it's using.
I think at some point in time, I had a version of 4.2 that worked with _FillValues correctly, but I no longer have access to that version anymore to do a comparison...
