ArcMap

Accessing OS Maps API via ESRI ArcMap

ArcMap is a desktop Geographic Information System (GIS) software that allows you to create, edit, analyse, and share maps and geographical data.

What you need

• OS Maps API added to an API project in the OS Data Hub with an API Key. See Getting started with an API project for more information.

• ESRI ArcMap version 10.5 or later

Note: We used ArcMap 10.5 to create these instructions.

Instructions

1. In ArcMap open the Catalog window.

2. Expand GIS Servers to display the various servers which can be added into ArcMap to make a connection with the OS Maps service on the OS Data Hub.

3. Double-click Add WMTS Server.

   
4. In the Add WMTS Server dialog:

   • URL: Copy your full OS Maps API WMTS endpoint address from the OS Data Hub and paste it into this field.

   • Other fields: Leave these as they are. No other information is required.

   • Click OK.

     
5. OS Maps API on api.os.uk will now display in the list of GIS servers in the Catalog window.

   
6. Click the Add Data button.

   
7. In the Add Data dialog, browse to the folder where the OS Maps API is located, expand it, select your preferred data layer, and then click Add.

   

   The data should now display in the map area.

8. Use the zoom or set scale tools to view different scales of mapping available. The OS Maps service offers different options for the data to be viewed, either under British National Grid (27700) or Web Mercator (3857).

   
9. You can save the project as an .MXD file when finished. It should not be necessary to add the service again.
