[Geoserver-users] Geoserver highlighting features from GetFeature request

Brad_Spencer · February 29, 2020, 1:25am

Guys,

I am able to do a GetFeature request that returns a list of several thousand feature ids (attribute PKs). The only way I have been able to highlight these on the map is via SLDs but that is very slow and really not workable.

So I was wondering does Geoserver (12.2) have anything to highlight these returned features (polygons) as part of the GetFeature request?

I am now looking at using a combination of SLD (for rendering ) and CQL_FILTER IN filter for filtering. But this also seems to be a very clunky option.

Any thoughts?

Cheers,

Brad Spencer

Since you are only talking several thousand features consider using wfs and doing the selection client side (with a library like open layers).

Jody,

So are you suggesting using vectors in the client? I do have the geometry so could do that; I hadn’t thought of that but will give it a go.

Cheers, Brad…

Hi Brad,
looks like you want client side filtering and styling, without having to reload data from the client?
OpenLayers should be able to do that with the GetFeature WFS output format, if you want to try something
different, you can also install the Mapbox vector tiles plugin, MVT are supported by both OpenLayers and
Leaflet

Cheers
Andrea
