Hi all,
I'm trying to set a maxextent on a WFS so it doesn't try to request
features when the layer isn't in view. Just adding a maxExtent to the
layer isn't working. When the area is outside the viewport, the WFS is
still being queried. I've checked with a WMS layer and the maxExtent
itself is working as I hoped.
I'm currently using a vector layer with a BBOX strategy, should I use a
different strategy? Or if it isn't possible by default, can someone give
me pointers where I should start hacking?
The configuration of the WFS layer is:
,skGN : new OpenLayers.Layer.Vector("Norway GN",
{
maxExtent: new OpenLayers.Bounds(5,58,10,62),
displayOutsideMaxExtent: false,
strategies: [new OpenLayers.Strategy.BBOX({resFactor: 1})],
visibility: true,
styleMap: GeoViewer.Styles.pointStyles,
projection: new OpenLayers.Projection("EPSG:4258"),
protocol: new OpenLayers.Protocol.WFS({
formatOptions: {xy: true}, //Set to false for latitude
longitude order
version: "1.1.0",
outputFormat: "text/xml; subtype=gml/3.2.1",
srsName: "EPSG:4258",
extractAttributes:true,
url: GeoViewer.Catalog.urls.SK_WFS,
featurePrefix: "gn",
featureType: "NamedPlace",
featureNS:
"urn:x-inspire:specification:gmlas:GeographicalNames:3.0",
geometryName: "geometry",
maxFeatures: "50",
schema:
"http://esdin.geodan.nl/fgi/SK/deegree2-wfs/services?service=WFS&version=1.1.0&request=DescribeFeatureType&typeName=GN:NamedPlace&namespace=xmlns=(GN=urn:x-inspire:specification:gmlas:GeographicalNames:3.0)"
})
}
)
Regards,
Steven
