Refining by Text String

Your initial search may return hundreds or even thousands of layers. Scanning all these layers to find the most relevant one could take a long time. You need to refine your search.

1. Refine your search to receive only layers that include sea surface temperature.

   layers = wmsfind('temperature');
   sst = layers.refine('sea surface');

2. Refine the search again to include only layers that contain the term "global."

   global_sst = sst.refine('global');

3. Display one of the layers.

   global_sst(4).disp

   Sample Output:

              Index: 4
        ServerTitle: 'NASA SVS Image Server'
          ServerURL: 'http://aes.gsfc.nasa.gov/cgi-bin/wms?'
         LayerTitle: 'Background Image for Global Sea Surface ...
                     Temperature Anomalies from June, 2002 ...
                     to September, 2003 (WMS)'
          LayerName: '2906_17499_bg'
             Latlim: [-90.0000 90.0000]
             Lonlim: [-180.0000 180.0000]

Refining by Geographic Limits

You can search for layers in a specific geographic area.

1. First, find hurricane layers.

   layers = wmsfind('hurricane');
   

2. Refine your search by selecting layers that are in the western hemisphere.

   western_hemisphere = layers.refineLimits ...
      ('Latlim',[-90 90], 'Lonlim', [-180 0]);
   

3. Refine again to include only layers in the western hemisphere that include temperature data.

   temp_and_west = western_hemisphere.refine('temperature');
