<div>You are right in that we shouldn't base any of our
mapping on what is visible on Google Streetview. Which is
why I was suggesting that somebody go check it out locally.
I've been looking at Belgian aerial imagery we are allowed
to use, taken over several years. But nothing useful can be
seen on them either. What can be seen is that almost never
more than 1 car was parked there when the planes flew over.
So it's definitely not a parking lot.<br>

I don't think we really have a way to tag an empty piece of
land with no defined "function" nor vegetation on it,<br>

I have overlaid OSM with the PICC (the digitalized version of those
aerial photographs).<br>
The PICC shows nothing more than the road border.<br>
<br>
The PICC has a 20cm precision, is extremely well done and we can
trace it (not to be confused with "copy").<br>
I often <b>highly</b> recommend to use the PICC with JOSM in
Wallonia.<br>
In fact, I'm spending much time to use them to correct what is
neigbouring what I'm mapping.<br>
Often, for example, the buildings are traced as roofs based on
imprecise, vague aerial photos.<br>
PICC shows building bases instead, very cleverly and precisely
calculated from multiple photo angles.<br>
And with Area Selector, one can trace a streetfull of houses in a
single click each, including numbers.<br>
I've been asked why ID and Potlatch would be worse than JOSM.<br>
I don't know. Just that when I meet something to leave as is, I know
and I can check that it's JOSM.<br>
See my picture. It's Potlatch.<br>
The "area" is offset 2 m on the right and 6 m on south.<br>
The building is 5 m away from its place and it has no number 2.<br>
The pedestrian crossings 2m and 5m, the wood on the right 6 m.<br>
Etc ... Often, more complicated maps are simply horrifying.<br>
The roads are mostly right but I believe that it's better to follow
PICC's way choices closely to show that PICC was used. And PICC does
the conversion of curved to straight lines for you.<br>
Mistakes are sometimes easily corrected with JOSM's Improve Way
Accuracy, but it's harassing to spend much time doing that while
other mistakes continue to be made. And mapping a new house is much,
much faster than correcting a bad one.<br>
<br>
<b>PLEASE, PLEASE</b> use PICC with JOSM in Wallonia !!!<br>
Wallonia have lost 6 years while I was trying to have the SPW
correct their PICC server's mistake and I was helping JOSM to
improve.<br>
JOSM is not really difficult to use. Use it more ans more in
parallel with another software, which you can use when you're stuck
until you find out how to do it with JOSM. You will appreciate what
more you can do with JOSM.<br>
<br>
Cheers

If not, you might consider not fixing it.
Yes it will be a useless<br>
polygon in the database, but isn't that
better than changing it e.g.<br>
to a parking lot while it is a private
property ?<br>
<br>
just my .5 cents<br>
