Hello,
We have this Openlayers 4 based application that can use WMS layers. It uses
such via a 2.11.2 Geoserver. It has a search function that creates a
getFeatureInfocall for search hits. The call is created like so:
var mapView = Viewer.getMap().getView();
var url = spec.layer.getSource().getGetFeatureInfoUrl(
spec.feature.getGeometry().getFirstCoordinate(),
mapView.getResolution(),
mapView.getProjection(),
{
'INFO_FORMAT': 'text/html',
'feature_count': 1
}
);
The thing is that it quite often wants to return several features (of the
always one layer being queried) which means it quite often does not return
the right one. The features of the layer do not overlap so it seems
improbably that the getFeatureInfocall would somehow target an exact
intersection between three features (which would likely not return three
features anyway).
Like this call
https://karta.eskilstuna.se/geoserver/wms?SERVICE=WMS&VERSION=1.1.1&REQUEST=GetFeatureInfo&FORMAT=image/png&TRANSPARENT=true&QUERY_LAYERS=sokvyx_fk_ay_esktn&LAYERS=sokvyx_fk_ay_esktn&TILED=true&INFO_FORMAT=text/html&feature_count=12&X=346&Y=237&WIDTH=512&HEIGHT=512&SRS=EPSG:3010&STYLES=&BBOX=150264,6583802.8,150622.4,6584161.2
where I set the feature_count to 12 the features being returned are three,
but why? (We would expect one based on
spec.feature.getGeometry().getFirstCoordinate() )
It happens for polygon layers as well as point layers.
Is there a way to determine and/ or influence the actual search radius of
the getfeatureinfo-request?
