I have a requirement to set thresholds on values to display on a map request to a NETCDF backed coverage store. For example, I have a layer for surface temperature, and they want to be able to only display areas on the map that are between 25 and 30 centigrade. Is there a way to achieve this with Geoserver? I've attempted to use CQL_FILTER but this only results in errors like "Error rendering coverage on the fast path" so I think that must not be the correct manner to produce filtered results. Any advice on how to achieve this requirement would be greatly appreciated.
Thanks! Steve Ferguson
