The middle intersection looks very wrong. Want to redesign it.
There for need to know if the aerial image on "Wallononmap" are
still corresponding with what is out there ? Or are there other
images ? <br>
The same with intersection north and south of it I need to connect
directly good on those also. <br>
Check this in editor: <br>

check aerial image I want to work with. No Mapillary image
yet. <br>

The problems are:<br>
<ul>
<li>That the roads are drawn too wide and one cannot see the turns
they make to enter or leave the main road; "we should not tag
for the renderer" they say but report the problem to them. But
maybe changing the road types as soon as they start turning and
not when they enter the side road would help.<br>
</li>
<li>That the mappers did not use JOSM+PICC (rarely needing the
orthophotos because PICC is rarely wrong), they used Potlatch
and ID; but in this case the photos are necessary; using BE
SPW(allonie) 2012-2013 aerial imagery is clearer that 2015 which
is clearer that 2016.</li>
</ul>
<b>PLEASE USE JOSM + PICC</b>: I have spent much time getting them
working. I have been repeatedly laughed at when I was requesting the
SPW to correct their projection bug and I kept hearing "we cannot
copy yet" which is not what we are doing. <br>
If I had been heard, we would have been able to map Wallonia
correctly since 2010.<br>
I am doing <b>a lot</b> of corrections (Jakka seems too), often
moving houses and other elements by 2, 3, ... 5m or more, adding
numbers, using Improve Way Accuracy mode to straighten roads, etc.<br>
With JOSM a house is drawn, including increasing number, in a single
click. Correcting a badly mapped one takes much longer and one feels
like erasing it.<br>
<br>
I doesn't look like this intersection changed over the years nor
lately (latest OSM topology around 2013).<br>
<br>
Here is how you see that intersection with JOSM and PICC:<br>
<br>
<a
href="http://www.papou.byethost9.com/maps/bad/route%20du%20Condroz%20PICC.png">route
du Condroz PICC</a><br>
<a
href="http://www.papou.byethost9.com/maps/bad/route%20du%20Condroz%20a%c3%a9rienne.png">route
du Condroz aérienne</a><br>
<br>
You can see that PICC is right.<br>
The OSM two lower main lanes are offset north by more than 2m in the
middle and to the right.<br>
The upper one makes a bump that it shouldn't do, it should go
straight on.<br>
The turns going diagonally make no sense. They should go straight
and then make a sharper turn.<br>
Like the one coming from the left: it should be passing somewhere
over the stopped car.<br>
They should certainly not connect (on a dot in common) with the
other ways they cross !!!<br>
==> beware not to destroy relations when changing those dots
erroneously belonging to 2 ways:<br>
JOSM will warn you but I'm not sure about the others: they destroyed
my relations.<br>
The yellow, north-south roads are not precisely in the right place
either.<br>
<br>
Hoping this and the PICC can help,<br>
Cheers <br>
Cordialement, <br>
