<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>

<div>I'm fairly lucky in that in the last three
years nothing much has changed locally. The
highways have stayed much the same. Most
buildings are still there.
<div> </div>
<div>If you use Bing to add things then
realistically it fills in gaps in the map. If
you delete things because they are not in Bing
that is a quite different matter.</div>
<div> </div>
<div>Does it matter if the mapper lives more
than five miles away? Well I've mapped places
a few thousand miles away but they were places
I knew very well as I used to live there.</div>
<div> </div>
<div>I don't think OSM will ever be completely
accurate. Having said that it is still very
useful for many purposes.</div>
