Public Mapping

Digimap has been working on the Public Mapping project which enables 3rd parties to develop web sites and applications using the Government of Jersey base mapping, without incurring any licence costs.

The generalised Jersey base map, the Jersey Public Map, is provided by the Government of Jersey using Esri’s ArcGIS Online system and is licensed for use free of charge subject to the following conditions.

  • 3rd party developers outside of the Government of Jersey will be required to sign a Public Mapping agreement
  • 3rd party developers and users within the Government of Jersey need to register their use of the data so that they can be notified of any changes to the system.

Once you have registered you will be issued with an API key which will grant access to the mapping data. Please email for more information on the registration procedure.

Technical details

The Public Mapping project serves the Government of Jersey base mapping using an ArcGIS tiled service, which serves image tiles of the map at various scales in order to provide optimum speed and performance. Developers use a Digimap provided API to request the current REST endpoint of the Public Maps. This ensures that the current mapping data endpoint is used.
The expected workflow is to use the Digimap API to obtain the required mapping data and then use that result with the Esri API. Please see the demo pages for example code.

Demo Site

Please choose the Guernsey or Jersey Public Mapping demo.
These demos contain sample code to obtain the REST endpoint for a map and to display it using the Esri JavaScript API.
