h2. GetPointValue
20 2 Ernst de Vreede
21 2 Ernst de Vreede
GetPointValue is kind of a shorthand for GetFeatureInfo. It enables one to do a GetFeatureInfo like request, without specifying a WMS GetMap request.
22 2 Ernst de Vreede
This can be used to retrieve for example a time series of data for a certain lat/lon coordinate or, in the case of ensemble data to get all 50 timeseries for a "plume" image.
