  • Where do I find the data my device is collecting

    Hi, I'm a newby to all this. Have set up a ADS-B receiver and I think I'm uploading something to FR24. Is there a file kept on my Pi that I can review that shows what data I am collecting and sending to FR24? Or, can I download my data from somewhere?

    Thanks

    Andrew

    Tracked aircraft list under

    Http://the.pi.ip.goes.here:8754

    But it is not logged without extra software

      How to pipe dump1090 decoded data to a file?

        In a browser use following address to latest file:

        IP-of-Pi/dump1090/data/aircraft.json

        In SSH window, following command will list all the aircraft.json files (current & history):

        ls /run/dump1090/

          Have you checked the local map?

          IP-of-Pi/dump1090

          If you want some statistical graphs or a better map, checkout this thread:
          https://forum.flightradar24.com/thre...090-et-cetera/

          You can assume FR24 is using all the data you receive when it needs it.
          Normally if you are somewhere with other feeders, duplicate information received by other feeders is not sent to FR24.

          Maybe you haven't found the statistics page yet?
          https://www.flightradar24.com/account/data-sharing

          Click on show statistics for your feeder.

            That looks like what I want. Tx

            Hi, Many thanks.

            Have had a quick look and it looks like data in json files.

              The json file is changing very frequently. So you need to download/copy the data every few seconds which give you a large amount of files and data. In addition not everything is in this data, so you might need to run a query against a different data source to get the complete information (e.g. Aircrraft manufacturer, origin, destination etc.)

              I wanted to do something similar having a DB which aircraft are passing my receiver on a daily basis. But i gave up due to the amount of data and the programming.

              Or with the example above, you need to keep another device with PuttY running 24/7. At the end you still have a large file with lots of information.

                Hi Magnum, that's pretty much what I'm aiming for. It's a hobby project but I also do this sort of thing for a living

                Thanks

                  Even if you are going to write your own data collection, it will be worth taking a look at this:

                  https://github.com/wiedehopf/graphs1090#graphs1090

                  You can also extract data from the database graphs1090 creates, for example like this script does:
                  https://github.com/caiusseverus/adsbcompare#comparesh

                  Here in this file are some commands extracting data from the round robin databases, that file is run to create the data files used by adsbcompare.

                      In this case you could either copy the created aircraft.json and parse it on the Raspberry through a json converter as csv. But be careful writing that often to an SD card. I've tested it with a network harddisk connected to my network.
                      But it's still a high amount of data and you need to run a query against a master database which contain the core data for any aircraft. There are several SQLite versions available, also scripts doing the job on the Raspberry

                      Or you can simply use the script of TomMuc where it goes to a MYSQL DB. Depending on the frequency it collects every message and you could imagine it's a huge amount of data.
                      Link to more information: https://discussions.flightaware.com/...d-filter/26619

                      Initially i did the script for the JSON file once a minute even with the risk losing some aircraft which showed up and disappeared within that minute.
                      Maybe the MYSQL version works better if you tweak the script for your needs

                        graphs1090 does not use mysql.

                        collectd with rrd-tool uses a round-robin database for each parameter captured.

                              Hi, I tried setting up using your article "Data logger with .." came unstuck with trying to install some of the modules.

                              I think what might do is set up a Python script to process the json files into csv and then analyse data from there.

                              All the best.
