Intro to FeatureLayer

Explore in the sandboxView live

This map shows carbon storage of trees in Warren Wilson College. It does this by adding a FeatureLayer to a map. A FeatureLayer can either be created from an array of graphics, a PortalItem, a Map Service, or a Feature Service.

This sample uses a feature service to create the FeatureLayer, as shown below.

const featureLayer = new FeatureLayer({
  url:
    "https://services.arcgis.com/V6ZHFr6zdgNZuVG0/arcgis/rest/services/Landscape_Trees/FeatureServer/0"
});
map.add(featureLayer);

By default, the FeatureLayer renders the features using a Renderer defined by the feature service. You can customize this by setting the renderer property of FeatureLayer.
