Hello,

I saw you requested a review.

First, I suggest you read the comments that have been emailed to you after your former edit on May 31.  User Jakka made important comments to help you improving the map.  We finally had to delete your changes because it contained way too many mistakes, such as invalid addresses.



Here are some comments below.

1) Parking areas

amenity=parking is for large parking structures.  Think about a car park in front of a supermarket or a railway station.
Having a few spaces along the road is not necessarily drawn like this, we prefer adding regular attributes to the road.  Should you insist drawing them separately, please add an extra tag to them, e.g. parking=lane.

(Not doing so will make the map look completely ugly and stupid, and will annoy users.)


2) Footways

Adding sidewalks or footways is cool.
But never create unfinished structures.
Example here: https://www.openstreetmap.org/way/1194026828  This footway starts at one point and terminates in the middle of nowhere.
OSM is used in real-life to route users, sometimes blind people.  It is the responsibility of every mapper to ensure not to create a mess.  Should the sidewalk really be interrupted here, add a "noexit=yes" tag on the last node.  Otherwise, connect it or don’t draw footways at all.


3) Shapes

We value quality over quantity.  If you draw objects, please try to make the extra bit of effort to draw realistic shapes.

This looks like an ugly trapeze.
Even the online editor has an option to automatically make it a rectangle.  Use it.


4) Buildings

Never draw buildings according to aerial imagery.

When you are editing, look for the Backgrounds button on the right part of your screen.  It shows a list with other background layers.  In Flanders, the right one is "Digitaal Vlaanderen GRB".  It gives the outline of buildings (i.e. the outer walls).  This is okay to trace in OSM.
I repeat: never draw buildings according to aerial imagery.  (Aerial imagery is fine to locate low-height objects such as zebra crossings, benches, etc. but not for larger structures.  This is because those are images taken from aircrafts, and there is always some distorsion, which is proportional to the size of the object.


5) Traffic signs

https://www.openstreetmap.org/node/11083760954
"traffic_sign=yes" alone is useless.
The correct way to use those objects is by providing the code of the traffic sign.  (prefixed be "BE:" in Belgium)
For instance, a no entry sign barring access to a road is: "traffic_sign=BE:C1"
A give-way sign before entering an intersection is: "traffic_sign=BE:B1" and so on.

Happy mapping.
