[mapserver-users] Problems with time-enabled WMS (WMS-T) in a cascaded layer

Thu Mar 24 12:31:56 PDT 2011

Hello,

I am trying to make time-enabled WMS-T requests to a cascaded layer that
originates from the NASA MODIS services. I can successfully make calls
to directly to the NASA service as below:

http://neowms.sci.gsfc.nasa.gov/wms/wms?version=1.1.1&service=WMS&request=GetMap&SRS=EPSG:4326&FORMAT=image/jpeg&STYLES=&BBox=-120.000,26.000,-97.000,44.000&Width=600&Height=470&Layers=MOD13A2_E_NDVI&TIME=2000-02-18

...other applicable dates include 2000-05-09, 2000-03-22, and
2011-02-02...

The NASA getCapabilities URL for this layer is:
http://neo.sci.gsfc.nasa.gov/FGDCMetadata?datasetId=MOD13A2_E_NDVI

and the NASA getCapabilites URL for the entire WMS service is:
http://neowms.sci.gsfc.nasa.gov/wms/wms?version=1.3.0&service=WMS&request=GetCapabilities

When I try to pass a &TIME argument to the cascaded layer, I only get
the image for the default time as specified in the NASA getCapabilities
call to the WMS service....

My cascaded URL looks like this:
http://edacwms.unm.edu/cgi-bin/mapfiles/epht_environment/epht_enviro_wms?version=1.1.1&SERVICE=WMS&REQUEST=GetMap&FORMAT=image/jpeg&STYLES=&SRS=EPSG:26913&BBOX=-1011825.41,2963772.82,1141463.33,4903085.27&Width=600&Height=470&Layers=MOD13A2_E_NDVI&TIME=2000-05-09

and the LAYER definition looks like this:
