Hi,
Relations 11911717 and 11911812 are broken. See https://tools.geofabrik.de/osmi/?view=areas&lon=148.85632&lat=-35.50630&zoom=8&opacity=0.72 Good luck.

Side note The imagery used cannot be the DCS NSW Imagery as that does not show boundaries...

Error .. mine.
"pained over" should be "painted over"

Hi

Arr.. no.

Only one relation is required, not two.

The relation should then have 2 members;
way/867936796 with the role outer
way/867936797 with the role inner

Next issue: way/867936796 has the same tags as the relation ... so the hole in the middle of the relation is pained over because the way says it is all water... remove the tags from the way and that will than leave the relation.

----------- Hope that makes some sort of sense.

See https://tools.geofabrik.de/osmi/?view=areas&lon=143.76701&lat=-37.77523&zoom=12 for some issues that should be fixed.

Hi,

Multipolygon relations - thee other ways cannot share segments. See https://tools.geofabrik.de/osmi/?view=areas&lon=139.27571&lat=-35.12366&zoom=18

In this case I would make a single outer way with the correct tags on it and delete the relation.

This does not need to be a multiploygon! KISS

The simpler the objects in OSM the easier they are to understand for us humans and the easier they are to render for the computers.

Hi,

Errors in relation/11815440

1) Multipolygon relations outer ways cannot share segments!

See https://tools.geofabrik.de/osmi/?view=areas&lon=145.45605&lat=-30.87017&zoom=6

2) building=yes;house ... no. It is either a house or not.

Suggest separating the building or using building:part=*.

I would think there are some Casuarinas in the larger area at least.

Hi,

Do these exist yet?
If not then they would be best tagged with life cycle tags.. see osm.wiki/Lifecycle_prefix#Stages_of_birth

Hi,
Not all of the area named 'Plantation' is scrub. There looks to be a road area to the north and east looks to be trees. The name .. comes from where?

Hi,

Scarsdale Plantation looks to be an area used for forestry. While some areas maybe 'scrub' now they will be trees in the future, and some areas will be harvested - so no trees. Rather than continuously updating the areas vegetation which is a patchwork it is easier to tag the landuse=forest, without any natural=scrub/wood/near_earth and be done with it.

Hi,

You have added ways to the administration boundary of Newcastle. Corrected. Please take care.

Hi,
Error in tagging.

On Bringelly Rd there are the tags; oneway=yes meaning it is one way in the forward direction of the OSM way.

and

maxspeed:backward=80 ...???

As oneway=yes forbids going backwards ... Danger Will Robertson, danger.

The changes broke the administration boundaries for 2 councils.
Please take care when changing things - refer to the OSM standard layer as that should show any linked features.

No response.

Repaired as best I could not knowing the area.

When you add an area inside another area that conflicts between the two, that conflict needs to be resolved. Here you have added a scrub area inside a tree area. It cannot be both trees and scrub.
The tree area can be made into a multipolygon relation and the scrub (and water) area added as an inner to that new relation.

Have you visited this area?

There looks to be considerable conflict between areas tagged as 'scree' and 'bear rock'. Then there is the question of 'heath' and 'tundra'.

Hi,
Please use the 'Q' key to square up your building entries - assuming they are 'square'.

I would also like to know why you have deleted buildings already entered and what source you used for the changes.

Hi,
The name tag is for the name only. Not to describe what has already been tagged. e.g. name Basketball Court should not be used unless you know that is the true name. See osm.wiki/Names#Name_is_the_name_only

Not a question of 'may have', there are crossing buildings. Crossing buildings are identified by the JOSM validator before you download the data to OSM.
A better practice is to save the data to your local PC without downloading it to OSM. Then correct it later. Once corrected then download it to OSM.
