# Terrains

You can enable an **OpenStreetMap** terrain from the **Terrains** section of the project window:

This terrain can be useful for troubleshooting the global position of your data:

This OpenStreetMap mesh can also be useful with MissionGuidance. If you plan to use MissionGuidance offline, consider downloading the OpenStreetMap tiles using the **Download Map** button. This will bring you to the World Map menu, where you can select a region to download using the button in the top left:

Once you have selected your region and **Zoom Level**, click **Download Map**. The map tiles will now be cached and available for offline access.&#x20;
