Because GeoServer uses by default a bbox vs bbox intersection type for the bbox operator. You have two options: - disable "loose bbox" in your datastore configuration (available only for databases). This will however have the side effect of making the WMS significantly slower - use the intersection filter instead of the bbox one Cheers Andrea ----------------------------------------------------- Ing.
