If you have BlueFox account credentials, use them to log in. Administrator and Installer roles both have privileges to collect ground truth.
If you don’t have BlueFox account credentials, you can log in as a Ground Truth Collector by just entering your email address (without a password). You will see the list of sensors for which you are allowed to collect ground truth data.
BlueFox Administrators and Installers can assign a Ground Truth Collection role to any email address using either the dashboard or the mobile app.
