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.
