No response.

Edited as I see fit.

Note: I think the public transport stops are wrong - see public_transport=stop_position - they should be nodes not relations or ways.

Also relation/2455519.

3D... yes .. I've had a go at the Sydney Opera house ... over lapping roof lines are not yet part of OSM 3D. Even milti level 'rooms' are not done well. But it is a start. Unfortunately most of the opera house is off limits to mere mortals so I can only do some of the places.

HI,
Welcome to OSM..
In this changeset the way for an industrial area was changed such that it crosses itself, that is not good.
As your were not attempting to change the industrial are (? from your rather brief changeset comment of 'houses') I have removed the nodes, that are part of the buildings, from the industrial areas way.

Keep mapping and take care.

Hi.
Problem with way/710589362 (roof).
See https://tools.geofabrik.de/osmi/?view=areas&lon=144.94203&lat=-37.82109&zoom=17

Hi,
This moved node/2722423290 by 176 metres .. destroying the way/266724707 for Old Geelong Gaol.

I have reverted this section of this changeset.

Hi,
This has broken relation/2455511. It may have broken other admin relations too.

Hi,
Problem - https://tools.geofabrik.de/osmi/?view=areas&lon=155.07910&lat=-5.96080&zoom=18&opacity=0.82

Hi
Your added nodes make the way cross itself. Better to move the original node. For one example see..

https://tools.geofabrik.de/osmi/?view=areas&lon=155.38347&lat=-6.23341&zoom=18&opacity=0.82

I will leave you to fix this one, I have done 3 of yours.

Looking at the history
way/383391758/history

I'd say the way was created when TheSwavu tried to tidy up landuse over 3 years ago... probably created by spiting an existing way and leave this one be hind but without any tags or use. Anyone who then alters a node that the way uses then gets attributed as an editor of that way.

These are safe enough to delete.. but the nodes have to be left behind if they are used by anything else. They contribute to data bloat.

Please read osm.wiki/Good_changeset_comments

I think you would be better off using JOSM. While it is a more complex editor, it makes more complex things easier.

Fix one thing at a time - relation/9865313 has outer ways that share segments..
https://tools.geofabrik.de/osmi/?view=areas&lon=148.42135&lat=-36.39257&zoom=16

The shared segments can be deleted, but you have to leave the rest of the outer ways.

There are also overlapping areas of heath and rock ...

Might work ?
way/710543215 ? edit - 2 in browser editors .. I'm a JOSM user so both those editors I am not familiar with.

Hi
way/710543215 crosses itself. This needs to be corrected. See https://tools.geofabrik.de/osmi/?view=areas&lon=148.08965&lat=-8.88289&zoom=18&opacity=0.75

Hi,
The Bismark Sea has been reduced to a single node. See changeset/72897476

I'm looking around.. the Pacific is a single node as is the Atlantic. But the Red Sea is a relation.
I don't know. Possibly the larger seas could have arbitrary lines to show there approximate boundaries without using coasts etc? This would allow easy editing as they are divorced from things people usually edit, can be long ways and can over lap other seas. Having it as a single node means the size is not present ... not even the approximate size. Where does the Pacific extend? Does it include the Coral sea? Don't think a single node is a good solution... but then I don't know what is.

Hi,

This 'industrial' area looks to me to be 'commercial'. Looks to sell services and goods, not produce goods? So I have changed it to commercial.

Hi,

You have tagged sport here as tennis. These look too small to be tennis? Possibly volleyball??

I have separated out the netball courts. And made a single small court for the number of small courts that exist. It needs a sport tag and then to be copied ... The new way is number 709885620.

Error!

Place=island must form a single closed way, not individual ways that when connected together from a closed area.
For multiple ways to form an island .. use a multipolygon.

Humm ...
Deleting way/678904551 (which has no tags) has deleted the Timor Sea... I have restored this way and thus restored the relation for the Timor Sea.

While large relations make things difficult, deleting them is destroying data. Deleting the Pacific Ocean may make things easier for someone editing a beach in the California... but that hardly justifies it?

Some ideas for you?
a) Download only the coastlines and islands that you want to edit. Edit them. Then possibly upload them.. and 1 day later check that the mulipolygon relations are ok using https://tools.geofabrik.de/osmi/?view=areas&lon=147.21387&lat=-31.88315&zoom=6 .. and then fix them.

b) rather than deleting an island ... make your new way on a blank layer. On another layer download the present OSM island. Merge the new data on to the layer with the old data. Now use the tool 'replace geometry' and you now have the old way .. updated with your data.
