We have a specific point and would like to count all features in a circular area with center at that specific point.

The data is:

  • Stored in a shapefile layer created in QGIS
  • Served by GeoServer
  • Browsed by a web browser using OpenLayers
  • 2
    do you have a spatial database (like postgres/postgis)?

  • Yes, but I think it's not what I need in this case, as the features are all in shapefiles. Feb 22 '13 at 19:07
  • Yes but why you just dont put those shapefiles in a db and query over that?

Issue a WFS-hits request with a specific ECQL filter (maybe DWITHIN)

Example request
http://<server>/wfs/?&version=1.1.0&request=GetFeature&typeName=ns:layer&resultType=hits&CQL_FILTER=<ECQL FILTER>

The response is something like

<wfs:FeatureCollection numberOfFeatures="324" timeStamp="2013-02-08T18:18:28.649Z" xsi:schemaLocation="http://www.opengis.net/wfs http://schemas.opengis.net/wfs/1.1.0/wfs.xsd"/>
