Hi
I have strange problem, I am using postgres database for displaying map. For
streets map I have defined following SLD to display streets as per scale but
as result I could't get it as required. Map only showing first layer rule
and doesn't showing another layer as per rule scale.
...
MinScaleDenominator18000/MinScaleDenominator
MaxScaleDenominator36000/MaxScaleDenominator
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=WMSversion=1.1.0request=GetMaplayers=gn:BlueMarble_world_highresstyles=bbox=-180.0,-90.0,180.0,90.0width=660height=330srs=EPSG:4326format=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
