OpenStreetMap layer

View on GitHub
Sample viewer app

Add OpenStreetMap as a basemap layer.

OpenStreetMap layer sample

Use case

You may want to create a map with an OpenStreetMap; which is a free community-edited basemap.

How to use the sample

The OpenStreetMap basemap will display upon launch. Pan and zoom to explore the base layer.

How it works

  1. Create an instance of AGSOpenStreetMapLayer.
  2. Create an instance of AGSMap using the OpenStreetMap layer as the base layer.
  3. Set the map to the map view's map property.

Relevant API

  • AGSBasemapStyle
  • AGSMap
  • AGSMapView
  • AGSOpenStreetMapLayer

Additional information

The attribution text will be set to the required OpenStreetMap attribution automatically.

Apps that expect to make many requests to OpenStreetMap should consider using an alternative tile server via the AGSWebTiledLayer class.

Esri now hosts an OpenStreetMap vector layer on ArcGIS Online that uses recent OpenStreetMap data in conjunction with a style matching the default OpenStreetMap style. This layer is not subject to the tile access restrictions that apply to tiles fetched from OpenStreetMap.org.
