     29By adding parameter '''transparent=true''' to WMS Request, the returned image will be added '''NoData Value=0''' int the bands's metadata, then WMS client will consider all the pixels with 0 value is transparent, e.g:
     30
     31http://localhost:8080/rasdaman/ows?service=WMS&version=1.3.0&request=GetMap&layers=waxlake1&bbox=618887,3228196,690885,%203300195.0&crs=EPSG:32615&width=600&height=600&format=image/png&TRANSPARENT=TRUE
     32
     33If not add this parameter, the return image will not be added the metadata 'Nodata Value', therefore, will not be transparent in WMS client.
