Requested review /tips :
I would use the lanes tag only when the road is divided by a painted strip. If you intended to describe the width of a road use the width tag. Example for Fairway Drive: width=6

funny

This "House" is 18m long and 1m wide.
I guess you have no idea about the scale you are working in. Your Road tagging is also way off. Switch to JOSM and make use of all available Imagery to avoid things like this

Hi,
At the moment I do a basic validation for buildings with every changeset.
Fixing crossing buildings, area=yes tagged buildings and so on.
I also simplify round buildings, because I think that
less nodes will make future editing of larger areas more conveniant.
I do not believe, that there is a signifficant loss of information, going along with this praxis

What is this good for?

overlapping buildings!!!

Yes there are missing buildings on the spot. But this new buildings are intersecting previously drawn buildings, due to uncorrected imagery offset.

Hi,
My greatest Hobby is to delete stuff like this from time to time

building=roof
layer=1

fix your script

Please be more precise. Almost every building is of wrong size and shape

way/215479439/history
way/353613605/history
please be more careful when deleting stuff

Imo these residential areas
are not representing the real land use. Map Building only, like HOT is doing elsewhere in Zimbabwe.

Hallo,
Bitte keine Pfade als "unclassified" taggen. Der Abstand zwischen zwei Knoten sollte auch immer so groß wie möglich sein.
Gemessen mit JOSM measurement-plugin:
way/489877648 = ~0.6m
way/489877649 = ~2m
