How to add control on the map

Amazon Location Service allows you to add multiple controls to the map, including navigation, geolocation, fullscreen, scale, and attribution controls.

  • Navigation control: Contains zoom buttons and a compass.

  • Geolocate control: Provides a button that uses the browser's geolocation API to locate the user on the map.

  • Fullscreen control: Contains a button for toggling the map in and out of fullscreen mode.

  • Scale control: Displays the ratio of a distance on the map to the corresponding distance on the ground.

  • Attribution control: Presents the map's attribution information. By default, the attribution control is expanded (regardless of map width).

You can add the controls to any corner of the map: top-left, bottom-left, bottom-right, or top-right.

Adding map controls

In the following example, you'll add the map controls listed above.
