This will make all the roads show between 1:180M and 1:360M. Does not really make sense to me, a world wide map displayed in a little 600x300 image is, according to the scale computation rules provided by OGC for WMS/SLD, 1:280M: http://demo1.geo-solutions.it/geoserver/gn/wms?service=WMS&version=1.1.0&request=GetMap&layers=gn:BlueMarble_world_highres&styles=&bbox=-180.0,-90.0,180.0,90.0&width=660&height=330&srs=EPSG:4326&format=application/openlayers When setting up the scales use the GeoServer openlayers previous, the scale denominator displayed there is computed with the same rules so you can take it as a reference (though due to differences in floating point computation between java and javascript it will never exactly match the value computed by GeoServer) Cheers Andrea -- ------------------------------------------------------- Ing.
