Get started!

  1. Go to https://gnss-metadata.eu/site/login
  2. Type in your Login ID and password
Logging in to the M3G portal allows you to upload/update metadata of your stations, agencies, networks etc. The GNSS stations can be your own stations, but can also be stations owned by a third-party agency that has given you a mandate to maintain their metadata in M3G.

  • If your agency has already an account in M3G, then you can find your agency Login ID online, in M3G "Agencies", under the column "Unique agency ID".
  • If your agency is not in the list, contact the M3G team.

  1. Go to https://gnss-metadata.eu/site/login
  2. Type in your Login ID and then click on "Reset Password"
  3. All contacts designated by your agency (set up in your "My Agency" form) will get an email with a link to reset the password.
  4. Click on the link and chose a new password.
(If you did not receive the link via email (first check your spam filter), you are not listed in M3G as one of the agency contacts. You can ask one of your colleagues included in your agency contacts to reset the password, log in to M3G, and add you to the list of agency contacts.)

Quick start

  1. Go to https://gnss-metadata.eu/site/login
  2. Log in to M3G using your Login ID and password.

First, provide the information regarding your agency: go to the agency-specific tab (top right in the menu) and click on “My agency”.
Then:

  • Fill in the information in all mandatory fields (marked with *)
  • Enter all contact persons present in your site logs
  • (optional, but recommended) Add a public central contact email, which does not contain any personal information
If any other agency is involved in the operation of the stations (e.g. the agency owning the stations or the agency of the on-site contact) managed by your agency: go to the agency-specific tab (top right in the menu) and click on “Third-party agencies” and follow the steps above, as you did for the information regarding your agency.

  1. Go to the agency-specific tab (top right in the menu) and click on “Managed networks"
  2. Use to create a new local or national network if the network is not in the list. Make sure you do not try to set up a network that is already defined in M3G. In the main menu, “Networks” lists all networks already set up in M3G. Each network must have a unique abbreviation.

  1. Go to the agency-specific tab (top right in the menu) and click on ”New station”
  2. Follow the on-line help
  3. Click on “Third-party station”, if your station is owned by another agency (included as third-party agency in the agency-specific menu “Third-party agencies”)
  4. Propose your station to at least one network. Stations proposed to EPOS must also be submitted to a local/national network.

  1. Click on “Update” in the agency-specific tab (top right in the menu)
  2. Click on the icon from the data base in the “Export/import information” column
    (If the station is not in the list, follow the steps in 4. Set up/add a new station
  3. Validate, iterate if necessary and save.

  1. Go to the agency-specific tab (top right in the menu) and click on “Update”
  2. Click on the icon in the “Export/import information” column to upload the site log from your local disk
  3. Validate, iterate if necessary and save.
Note that:
  • After submitting the site log, all contact persons (except if central public emails are used) mentioned in the site log will receive an email with subject “[M3G][REQUEST] Publication of your personal data”. As soon as the person has replied to this email (by clicking on one of the links inside the email), he/she will stop receiving this kind of emails.
  • M3G also has a feature that enables you to save a site log as draft.

M3G offers some of its functionalities through a RESTful HTTP API that allows you to interact with M3G purely as data that can be uploaded, accessed, searched for, etc. via HTTP requests. At present, M3G allows you to retrieve info on a given M3G entry (i.e. a network, a station), update part of a station site log or ask a query to locate many M3G entries at the same time. In the M3G menu bar "Documentation" you can access the "M3G API" submenu, containing:
