Getting layer name from getFeaturesAtPixel in OL4

Geographic Information Systems Asked by daudihus on January 3, 2021

I’m trying to build a popup that only shows feature info from certain layers. How do I get layer name?

I’ve tried this:

const features = this.map.getFeaturesAtPixel(evt.pixel, {
  layerFilter: ((layerCandidate: layer.Layer) => {
    if (layerCandidate.get('name') === 'my layer') {
      return true;
    }
    return false;
  }
  )});`

One Answer

var feature = Map.olMap.forEachFeatureAtPixel(pixel, function (feature, layer) {
                    options.layer = layer;
                    options.features = feature;
                    options.modify = self.currentInteraction;
                    options.sender = self;
                    callback(options);
                });

In these codes, you can get all layer properties with this command 

options.layer.getProperties()

title, opacity, visible and other details about layer.
