Subject: [Geoserver-users] GeoServer: how to get min/max values of a raster 
band?



Hi,



Is there a simple method (i.e. without adding extra WPS functions) to get the 
min/max values and/or the histogram of a given raster (e.g. geotiff) band, by 
using the standard services of the GeoServer?



Mani Thanks,

Victor
