You've obviously not had to unpick situations like this (unjoining multiple area outlines from highways) to find a duplicated section of highway. Dystelegh Road had a duplicated section on top of Chantry Road that I traced and deleted after correcting the grass areas.

I know things look right when rendered but it does make the job of correcting problems much more difficult and time consuming.

Duplicated highway sections removed.

Hi, surely these grass areas don't extend right across highways, that would make driving very difficult and possibly dangerous. Also grass verge areas should not be joined to a highway center line.

Could you please rectify the problems?

Regards Bernard.

Hi, Welcome to OpenStreetMap.

Your building outline duplicated an existing building, so I've removed it.

Regards Bernard.

Please see the comment about the other AED

Hi, If the AED isn't inside where is it? On the wall outside? Then it should be joined to the wall in the correct position and this indicated in a defibrillator:location= tag so folk can find it.

Need help just ask.

Hi, Welcome to OpenStreetMap.

Your new residential area is within an existing mapped residential area, Way: 3707308. So it's not needed, (it wouldn't be tagged as a house anyway). I've removed the area, Way: 1455256230

Don't stop mapping though, the houses can be mapped. Need help, just ask.

Regards Bernard.

Hi, Welcome to OpenStreetMap.
Are you sure your mapping is correct? Are the apartments now a wood surface foortway? Is there really a footpath between the houses? Has that area now become a new residential area?

Regards Bernard.

Several duplicated highways removed

Hi, Welcome to OpenStreetMap.
Unfortunately, you dragged the AED and joined it to the road footpath junction. I've repositioned it.

Regards Bernard.

Hi melody Tej,
I'll remember that for the future. Actually I wasn't looking at any level tags at all, I don't think they were mentioned in the task description.

Thanks & Regards Bernard.

Hi, Welcome to OpenStreetMap.
No need for a POI for the playground, the area is tagged as such.

Regards Bernard.

Hi, Welcome to OpenStreetMap.
OSM has a practice of "One feature, one OSM element". Thus no need for a pin as the building is tagged with the feature. I've amended the tags with your new info.

Regards Bernard.

There's been no response so I've removed several duplicated highways, footpaths placed on top of existing roads in 3 changesets.

Hi, Welcome to OpenStreetMap.
It's OSM practice to make amendments/corrections to any existing feature rather than deleting and redrawing. Thus, all the mapping history of a feature is maintained.

I've reverted the changeset then amended the original highway to the new position adding the new tags.

Regards Bernard.

You are duplicating highways!

Thats a TravelLodge, fiction removed.

Thats a TravelLodge, fiction removed.

Areas and tags tweaked

Hi, Welcome to OpenStreetMap.
Some of your footways are placed on top of existing highways, creating duplication that could disrupt routing. Thus, the warnings above about crossing highways.

Could you please correct these problems? Need any help, just ask.

Regards Bernard.
