TIP

To be able to synchronise a project, you need to:

  • be signed in to your Mergin account
  • be connected to the internet
  • have write permission to the project

# Manual synchronisation

You can synchronise local changes by tapping the sync button in the map window. The sync button will stop rotating once the synchronisation process is finished and the Successfully synchronised message will appear at the top of the window.

Pressing and holding the sync button opens the Project status, where you can see changes yet to be synchronised.

# Automatic synchronisation

To allow automatic synchronisation in Mergin Maps Input, navigate to Settings and toggle on Automatically sync changes.

As changes will be done during the survey, such as adding new features or changing field values, the synchronisation will start automatically. The sync button will indicate that synchronisation is in progress and once it is done, the Successfully synchronised message will appear.

autosync

If changes can not be synchronised automatically, e.g. when internet connection is lost during the survey, the changes need to be synchronised manually after reconnecting to the internet.
