Just take care with using the GPX files on the GR Vlaanderen website
to <u>correct</u> GR routes on OpenStreetMap without further
concerns.<br>
The GPX files on that GR website are not always up to date. You
should at least take in account the route corrections
'Trajectwijzigingen' on the <a
href="http://www.groteroutepaden.be/nl/route/45/gr-5-noordzee---middellandse-zee---deel-vlaanderen.html">GR
website</a>.<br>
Those corrections are sometimes in the GPX file and sometimes they
aren't. And sometimes the route has been changed in the field but
those changes are not in the GPX file nor is there already a change
description on the GR website.<br>
So using the GPX files on the GR website to correct GR routes on
OpenStreetMap can lead to creating faults instead of correcting one.
Checking in the field can't be improved. <br>
<br>
Some examples I recently encountered in Limburg: <br>
<ul>
<li> the GR 561 between 'Dilserbos Parking' and Opoeteren. I had
the GR GPX on my GPS when I ran that track and discovered that
the marks in the field took me along a deviating route on some
points.Afterwards I saw that the deviations in the field are
described as 'Trajectwijzigingen' on the GR website but they
weren't on the GPX.</li>
<li>The GR5 between Bokrijk and Kinderboerderij Kiewit has been
changed in the field recently. It no longer follows a asphalt
road but goes through a meadow as other walking routes do. This
change isn't on the GR website but it is correct on
Openstreetmap <a
href="http://hiking.waymarkedtrails.org/#?map=16%2150.9625%215.3861"><a class="moz-txt-link-freetext" href="http://hiking.waymarkedtrails.org/#?map=16!50.9625!5.3861">http://hiking.waymarkedtrails.org/#?map=16!50.9625!5.3861</a></a></li>
</ul>
Besides corrections I see the advantage of using GR GPX files to put
a GR route on Openstreetmap that was't tagged. But that is only
possible for so far tracks or paths that are used are already on
OSM. The qualification of those ways aren't on the the GPX file. You
can only know them by following the GR in the field.<br>
<br>
But I like GR Vlaanderen because they already offer GPX files for
free on their website. In contrary to GR Sentiers in Wallonie where
you can only find the GPX files of GR's for free on Openstreetmap (<a
href="http://hiking.waymarkedtrails.org/#route?id=4580796&map=12%2150.6159%215.7517">Waymarkedtrails.org).</a><br>
And they are all far better than GR Sentiers France that forced
Openstreetmap to delete the tagged GR's because of copyright
protection in France (after a holiday in the south of France I put a
major part of GR <span class="st"><em>Route</em> des <em>Cathares
</em>on OSM. Meanwhile that GR relation that I did has been
deleted but the paths that I added are still on the map. And there
were new attempts to put that GR on OSM but for how long?).<br>

<div>Good news everyone! We're going on a long hike!</div>
<div><br>
</div>
<div>After contacts initiated by Jo, licencing advice by Glenn
and Ben, and a talk with Wouter and myself, the Flemish GR
organization today gave us the explicit permission to use the
GPX files of their routes for improving the GR routes mapped
in OSM.</div>
<div><br>
</div>
<div>This is only a first step, they are considering managing
their route information completely within OpenStreetMap. I
hope we can support them in this direction. There are all
kinds of ways that they can help us grow our community, and
ways in which we can support them. Feel free to start thinking
out loud in this thread.</div>
<div><br>
</div>
<div>Let's build something together which might inspire
organisations worldwide to follow their lead.</div>
<div><br>
</div>
<div>But enough with the emotions.</div>
<div><br>
</div>
<div>I already added them to the Contributors wiki [1] and I
have uploaded the supporting document to the wiki pages [2].
Maybe we can add a little section to some more Belgium wiki
pages too?</div>
<div>I made a little UMAP [3] to help with my first corrections
[4]. It's a public map, so feel free to use it (and maybe make
a simple tool out of it for tracking our progress in our
cleanup?). I started adding #groteroutepaden to my changesets
[4]. If we all do that, it might help make some cool
statistics.</div>
<div><br>
</div>
<div>The GPX files can be downloaded when you get to the page
for an individual route at the bottom of the download section
[5]. If you spot an error in the GPX or reality, you can send
it to them here [6]. </div>
