# Maps in Dashboard
The spatial data of your project can be displayed in the Map tab of the project on the dashboard. You need to be logged in to see the maps.
Usage details
Maps can be used with Team, Academia and Non-profit subscription plans.
They are not available for Individual or Professional subscriptions, Mergin Maps CE and Mergin Maps EE.
You can try this feature for free during the trial period.
# Maps content
In the maps, you will see your survey layers or raster layers that are packaged with the project. Other layers, such as online background maps or PostgreSQL layers are not displayed. The extent of maps is defined by the extent set in the QGIS project.
All maps in the dashboard use Mergin Maps vector tile service as a background map.
The content of the maps and of the Layers panel is refreshed after every synchronisation of the project. This means you should always see your current spatial data here.
The Layers panel lists all layers displayed on the map. The check button ✅ controls the visibility of layers.
# Maps extent
The extent of maps is defined in QGIS in the Project Properties.
When displaying maps on the dashboard, Mergin Maps uses primarily the project full extent defined in the View Settings tab.
If this parameter is not defined, the map extent will be set as the Advertised extent from the QGIS Server tab.
If there are no extent settings in the QGIS project, Mergin Maps will calculate the extent from layers in the project.
# Troubleshooting
# Map config does not exist
The Map tab of a project on the dashboard may display this error message:
Map config does not exist, please try update the project
This usually happens when the map was not initiated. All you need to do is to create a new version of the project: synchronisation of the project will activate the map content.
