Feature layer shapefile

View on GitHub
Sample viewer app

Open a shapefile stored on the device and display it as a feature layer with default symbology.

Image of feature layer shapefile

Use case

Shapefiles store location, shape and attributes of geospatial vector data. Shapefiles can be loaded directly into ArcGIS Runtime.

How to use the sample

Pan and zoom around the map. View the data loaded from the shapefile.

How it works

  1. Create a ShapefileFeatureTable passing in the URL of a shapefile.
  2. Create a FeatureLayer using the shapefile feature table.
  3. Add the layer to the map's operation layers.
