Workflow using WPS services. 2 WPS services are called: histogramprocess and gdalinfo.
Gdalinfo is WPS wrapper arround gdalinfo command (http://www.gdal.org/gdalinfo.html), stdout response will contain the image's metadata
Histograprocress, calculates the histogram for each image band. The process uses GDAL libraries and Numpy, and it runs best GeoTiff images
