Symbolize a shapefile

Display a shapefile with custom symbology.

Use case

While feature layers come with default symbology, you can apply custom styling to ensure that the content is visible and usable in the context of a specific map.

How it works

  1. Create a ShapefileFeatureTable, providing the path to a shapefile.
  2. Create a FeatureLayer and associate it with the ShapeFileFeatureTable.
  3. Create a SimpleRenderer to override the default symbology. The simple renderer takes a symbol and applies that to all features in a layer.
  4. Apply the renderer to the FeatureLayer by setting the renderer.

Relevant API

  • FeatureLayer
  • ShapefileFeatureTable
  • SimpleFillSymbol
  • SimpleLineSymbol
  • SimpleRenderer
