Hello. I am GIS Newbie.
I am currently publishing satellite images as layers in geotiff format.
And I am requesting it in wms and displaying it on openlayers.
I want to filter by giving a range of pixel values.
For example, if the layer has values from 1 to 1000, I would like to filter
values from 50 to 200.
I tried using the cql filter, but the result was not displayed.
Is there a way to filter raster data using geoserver?
Is there any good way to do this?
Thank you.
