    <div class="moz-cite-prefix">You can make the map quite precise and
      up to date by employing a GPS tracker. Here is, for example, a 431
      km GPS trace which I recorded with the Garmin 35 eTrex device (no
      affiliation) earlier this month in Mexico from inside the bus:
      <a class="moz-txt-link-freetext" href="https://connect.garmin.com/modern/activity/4330126920">https://connect.garmin.com/modern/activity/4330126920</a> . This GPS
      trace is also published to the OSM map.<br>
    </div>
    <div class="moz-cite-prefix"><br>
    </div>
    <div class="moz-cite-prefix">Garmin 35 uses the EGNOS, the European
      Geostationary Navigation Overlay Service, a satellite based
      augmentation system, in Europe, and the WAAS, the Wide Area
      Augmentation System, in the North America. It is capable to record
      a GPS trace for about 20 hours on a pair of cheap alkaline AA
      batteries even from inside the train, bus, car, or on bicycle.</div>
    <div class="moz-cite-prefix"><br>
    </div>
    <div class="moz-cite-prefix">It is possible to build a DIY,
      do-it-yourself, GPS tracker from and Arduino type micro-controller
      [1] and a 15 USD GPS module [2]. The total cost would be about
      30.- USD. There are videos on Youtube on how to do it.</div>
    <div class="moz-cite-prefix"><br>
    </div>
    <div class="moz-cite-prefix">So one can record a GPS trace while
      cycling around a new building or a park, then publish the GPS
      trace to the OSM map, and finally to map them precisely and up to
      date in an editor by the GPS traces, even if they are not on
      satellite images yet.<br>
