--- layout: example.html title: Vector Layer Hit Detection shortdesc: Example of hit detection on a countries vector layer with country information. docs: > The countries are loaded from a GeoJSON file. Information about countries is on hover and click is retrieved using the layer's `getFeatures()` method. For vector layers, this function resolves with an array of only the topmost feature. It uses a very efficient hit detection algorithm, at the cost of accuracy. For pixel exact hit detection, when performance is not a concern, use the map's `getFeaturesAtPixel()` or `forEachFeatureAtPixel()` methods. tags: "vector, geojson, click, hover, hit detection" ---
