Of cloud patterns in several wavelengths for all of North and At this position its Imager instrument takes pictures The GOES-12 satellite sits at 75 degrees west longitude at anĪltitude of 36,000 kilometers over the equator, in geosynchronous If multiple entries are returned, select only the first one from the server. The * character indicates a wild-card search. Supplying the query string, 'goes-12*katrina*visible*close*up*animation', to the refine method returns a WMSLayer array whose elements contain a match of the query string in either the LayerTitle or LayerName properties. Using the refine method is more efficient and returns results faster than wmsfind since the search has already been narrowed to a smaller set. Rather than searching the database again, you may refine your search by using the refine method of the WMSLayer class. In general, a search may even return thousands of layers, which may be too large to review individually. You can display only the LayerTitle property for each element by executing the command:ĭisp(katrina,'Properties','layertitle','Index','off','Label','off') Īs you've discovered, a search for the generic word 'katrina' returned results of many layers and you need to select only one layer. This display makes it easy for you to examine the entire array quickly, searching for a layer of interest. If you type, katrina, in the command window, the entire contents of the array are displayed, with each element's index number included in the output. LayerTitle: 'GOES-12 Imagery of Hurricane Katrina: Longwave Infrared Close-up (1024x1024 Animation)' If the useInternet flag is not defined, it is set to false. You can store the data locally the first time you run the example and then set the useInternet flag to false. For a list of common problems and strategies for working around them, please see the Common Problems with WMS Servers section in the Mapping Toolbox™ User's Guide. Often, this is a temporary problem and you will be able to connect to the server if you try again later. A function, such as wmsread, may time out if a server is unavailable. One of the challenges of working with WMS servers is that sometimes you will encounter server errors. Note that the WMS servers may be unavailable, and several minutes may elapse before the maps are returned. If the useInternet flag is set to true, then an Internet connection must be established to run the example. You can use a variable, useInternet, to determine whether to read data from locally stored files, or retrieve the data from the Internet. Since WMS servers are located on the Internet, this example can be set to access the Internet to dynamically render and retrieve maps from WMS servers or it can be set to use data previously retrieved from the Internet using the WMS capabilities but now stored in local files.
