How to use the Services

This page has links to instructions for using Esri UK’s online map and gazetteer services across the ArcGIS platform.

Enquire about subscribing to premium map services.


Map Services and Locators

A range of free and premium map services are available to use as basemaps throughout the ArcGIS Platform. For details of the maps available (content, display, data scale etc), see the individual links on the Free Services page and the Premium Services page.

Furthermore we have made available a number of free locators which allow you to search for locations (e.g. streets, places and postcodes), batch geocode and reverse geocode.

For details of the data in each gazetteer, and what types of search are possible, see the individual links on the Free Services page.

The online content services are delivered through ArcGIS Online as REST services that can be consumed directly by any client either within or outside the Esri Platform.
