Add a logo and an attribution to your map

Esri requires that when an ArcGIS Online basemap is used in a web app, the map must include the Esri logo and attribution.

Terms of use

What it means

1.b.vii. Licensee may not remove or obscure any trademarks or logos that would normally be displayed through the use of the Online Services without written permission. If Licensee is using non-Esri application development tools to build applications that access Esri's Online Services, Licensee must include attribution acknowledging that its application is using Online Services provided by Esri. Guidelines are provided in the Documentation.

You are not allowed to remove any logos, trademarks, or other similar attributions displayed when any of the following occurs:

  • You are using any Esri service. This includes services such as map services (e.g., basemaps), credit-based services (e.g., routing), or any other service created and hosted by Esri.
  • You are using any service that is hosted via ArcGIS Online.
  • You are accessing a service that a customer published from their own on-premises ArcGIS Server, and registered it with ArcGIS Online. For example, company ABC published their own services via ArcGIS Server and registered those services with ArcGIS Online. They then used those services within an app. ABC's services from ArcGIS Online would still need to be displayed with the proper logo.
  • You are using Esri services with third-party application development tools. To do this, you must add all appropriate logos and pertinent attribution. For an overall idea of implementing attribution when using a third-party API, see the section below describing how Esri Leaflet handles attribution.

The Esri logo and the attribution must be on or near the map whenever an ArcGIS Online basemap is present. The recommended location is the lower right corner of the map, but you can move them as necessary.

Esri logo and attribution

You can download the logo and attribution and paste the information into your app, or you can request the logo and attribution each time a user opens your app. Note that the attribution is different for each basemap.

The Esri logo is available at the following location:

The attribution for a basemap is available in the service metadata. For example, the request for World Imagery metadata is The information you need is in the copyrightText string. In this example, the attribution is Source: Esri, DigitalGlobe, GeoEye, i-cubed, Earthstar Geographics, CNES/Airbus DS, USDA, USGS, AEX, Getmapping, Aerogrid, IGN, IGP, swisstopo, and the GIS User Community. If you choose a static option of copying the information into your app, be aware that the attribution changes on a regular basis. You should regularly review the attribution, such as when you update your app.

If you're uncertain how to generate dynamic attribution, a recommended place to begin is Leaflet's basemap source code. The specific methods to note are the following:

If you are using Leaflet, multiple examples are available that include the logo and attribution. Many of the Leaflet examples also take advantage of dynamic attribution. As a user zooms and pans around, the attribution changes depending on the current extent. This reduces the amount of text in the attribution, and the attribution is always up to date.
