Hi TDS and/or ncWMS folks, I recently upgraded from TDS 4.2.10 to 4.3.16 and am noticing something strange in my WMS output. GetMap URL's that used to work fine in TDS 4.2.10 are coming up blank in 4.3.16. As a workaround, I discovered that changing my CRS from EPSG:4326 to CRS:84 fixes the problem. Seems like a bug with using EPSG:4326?? Here's an example using a ROMS ocean forecast of water temperature over central Hawaii. Using EPSG:4326 gives a blank map: http://oos.soest.hawaii.edu/thredds/wms/hioos/roms_forec_regridded/hiig/ROMS_Hawaii_Regional_Ocean_Model_Regridded_best.ncd?service=WMS&version=1.3.0&REQUEST=GetMap&FORMAT=image/png&TRANSPARENT=true&LAYERS=water_temp&CRS=EPSG:4326&BBOX=202.12371826171875,20.17714549791179,204.46517944335938,21.50418550077842&WIDTH=1705&HEIGHT=1034&TIME=2013-04-15T00:00:00Z&ELEVATION=-5&STYLES=boxfill/rainbow&NUMCOLORBANDS=256&COLORSCALERANGE=24.02441,26.03417 In contrast, if I switch this to CRS:84 I now get a color map as expected: http://oos.soest.hawaii.edu/thredds/wms/hioos/roms_forec_regridded/hiig/ROMS_Hawaii_Regional_Ocean_Model_Regridded_best.ncd?service=WMS&version=1.3.0&REQUEST=GetMap&FORMAT=image/png&TRANSPARENT=true&LAYERS=water_temp&CRS=CRS:84&BBOX=202.12371826171875,20.17714549791179,204.46517944335938,21.50418550077842&WIDTH=1705&HEIGHT=1034&TIME=2013-04-15T00:00:00Z&ELEVATION=-5&STYLES=boxfill/rainbow&NUMCOLORBANDS=256&COLORSCALERANGE=24.02441,26.03417 Oh... And I just found another workaround. If I switch to WMS 1.1.1 instead of 1.3.0, EPSG:4326 also works: http://oos.soest.hawaii.edu/thredds/wms/hioos/roms_forec_regridded/hiig/ROMS_Hawaii_Regional_Ocean_Model_Regridded_best.ncd?service=WMS&version=1.1.1&REQUEST=GetMap&FORMAT=image/png&TRANSPARENT=true&LAYERS=water_temp&SRS=EPSG:4326&BBOX=202.12371826171875,20.17714549791179,204.46517944335938,21.50418550077842&WIDTH=1705&HEIGHT=1034&TIME=2013-04-15T00:00:00Z&ELEVATION=-5&STYLES=boxfill/rainbow&NUMCOLORBANDS=256&COLORSCALERANGE=24.02441,26.03417 In short, I'm hoping that somebody can fix the WMS so that EPSG:4326 will not give me blank maps in WMS 1.3.0, but I have workarounds in the meantime so it's not pressing.
