Token-based data download — network EV

1. Request the access token

  • Send an e-mail to npotleca@ogs.it
  • Subject: Token request for the COLLALTO network
  • In the body state your first name, surname, e-mail address and organisation.
You will receive a signed token.asc file. The e-mail address you provide is enabled on the service manually, by the administrator: downloads are granted to that address.

2. Create temporary credentials

Run this command in the folder containing token.asc:

Command to obtain temporary credentials curl --data-binary @token.asc "https://nat-scp-srv.ogs.it/fdsnws/dataselect/1/auth" -o cred.txt
Command copied.
You will get a cred.txt file with a user:password pair valid for 24 hours. When the user:password pair expires, repeat only this command: the token remains valid until its own expiry date, and only then must it be requested again.

3. Select the data

Available channels differ from station to station: the list below updates according to the stations you select.

Time window (UTC)

Times are in UTC, not Italian local time. One day per request.

Stations

List loading, or JavaScript disabled.

Channels

Select at least one station to see the available channels.

4. Download the data

Run this command in the folder containing cred.txt:

Download command generated from your selection # Complete the form above to get the command.
Command copied.
Your selection includes channels that do not exist on every selected station. This is not an error: the service returns what it finds. The file will be smaller than expected, and this is why.
