<div class="moz-cite-prefix">Thank you, dikkeknodel. <br>
<br>
I also received an email message with an advice to acquire Garmin
eTrex. I've ordered the Garmin eTrex 35 Touch with the
pre-installed «TopoActive» Karte Europa, which is based on the OSM
data, as I understood:<br>
<a class="moz-txt-link-freetext" href="https://www.brack.ch/garmin-hand-gps-etrex-touch-370929">https://www.brack.ch/garmin-hand-gps-etrex-touch-370929</a><br>
<br>
It supports the EGNOS, European Geostationary Navigation Overlay
Service, which is supposed to correct the GPS signal. I have no
idea how it works in reality. It also has got the GPS and
barometric altimeters.<br>
<br>
Best regards,<br>
Oleksiy<br>

<p class="MsoNormal"><span lang="EN-GB">Thanks for all the great
advice. I’ve looked into uMap and it does the job perfectly.
With all the gpx of over a year of hiking imported it still
runs smoothly.

<p class="MsoNormal"><span lang="EN-GB">I would like to prevent
running into performance issues later though. Does anybody
know if it is wise to add ‘simplified’ versions of the gpx
to uMap instead of the original recordings with 1 s
resolution?

<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">Since the published data
is public, I just have to take into account not to import
gpx which start from my home since I value my ‘sort of
anonymity’.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-GB">To answer Oleksiy’s
question, I record with OSMand on a Moto G4 smartphone, that
works like a charm. Off course there is fluctuation due to
accuracy errors, I guess 10-15 m is achievable most of the
time, but close to near vertical mountains it becomes much
worse. <o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">It however does never
happen that I miss long stretches of data (except for
tunnels
</span><span style="font-family:"Segoe UI
Emoji",sans-serif" lang="EN-GB">😝</span><span
lang="EN-GB">). I did have that problem in the past, when
<15% battery charge and Android automatically started the
battery saving mode. That just turned of the gps antenna
whenever the screen was off. So now I have set battery
saving mode to off. <o:p>
</o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">Also OSMand does not
drain the battery much. Usually I do take a lot of notes
which OSMand attaches to the gpx and loads perfectly into
JOSM. Recently I also used the voice recorder of OSMand,
which really speeds up the note taking while on the go in
comparison to typing. These also load into JOSM via the gpx,
but some fiddling with the location of the audio is
required. Taking notes on the phone does have an effect on
the battery life off course. A 20 km hike in the mountains
easily takes 6-8h, which my phone reaches most of the time
on one charge in flight mode. I do have a power-bank as
back-up, and for multi-day hikes though.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">Altitude measurements
have always been a bit tricky with OSMand. I guess the raw
elevation data from gps fluctuates quite a lot, and the data
processing did not do a good job filtering errors from
actual elevation change. After a hike with 1000m elevation
gain according to the map, OSMand often showed I did
5000m... The graph of the track you can generate in OSMand
also showed a lot of spikes with instant ascents of
>200m. Recently that seems to have changed and the
measurements seem to better represent the actual situation.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="color:black" lang="EN-GB">Hi
_dikkeknodel,<br>
<br>
I have a question - how do you record a GPX trace during 20
km walk? It should be about 4 hours.
<br>
<br>
I also record GPS traces but usually for 15-20 minutes. I
use a phone with the OSMTracker app for Android with mixed
results. Sometimes it records a path well, sometimes it
turns the second part of the walk into a long direct line.
Such a trace I usually discard.<br>
<br>
Besides it empties the phone battery rather quickly. I
usually take a power-bank with me, but still it is not a
good solution to get a phone battery empty in mountains.<br>
<br>
I am thinking of getting a dedicated device which can record
the GPX files, on the OSM map, and also measure and altitude
more or less correctly. The question is - what device, what
model.<br>
<br>
Best regards,<br>
Oleksiy<br>
