Hi
The Conservation Area - Okuru-Waiatoto relation/19844694 has an issue with way Way: 1451048167 .. part of the way should not be in the relation?

Source - should add LINZ Imagery for area.

Where I got the boundary from this time? From the past chageset that entered the data .. and that got it from DCS (except it was some other name back then) data base down load. Back then a number of use got all the National Parks, State Forests and other things and got them into OSM. This is less work and less prone to error than tracing them out from the Base Map.
Form Imagery I prefer the DCS Imagery - more locationally accurate than Bing. And for more upto date Imagery Esri.

I have not checked the boundary lately.

Hi
The relation/20065830 Conservation Area - Stevens Wildlife Area is not closed.

Hi,
Comment? It looks to me like your trying to replace tree relations with tree ways.

In this changeset relation/19329027 is some 243 km north to south while you r new way1412902847 is 3 km north to south and is almost fully contained in the relation.

I have restored the relation to a fully closed outer and deleted your way.

Hi
relation/19949406 is not closed. The import has remove some 300 nodes from this relation. Error?

Hi,
Multipoygon relation/16692138 track is not correct!
Rule 1: outer ways cannot share segments.
Secondly .. what is being mapped and an 'outer' - the outside of the track and an 'inner' the inside of the track. It should be 2 ways - not toughing the outside should have the role 'outer' and the inside way should have the role 'inner'.
More? Read osm.wiki/Relation:multipolygon

A simpler method is the have a single way - this does not map the track width.

Oh .. link to Aust Data Sources page
osm.wiki/Australian_Data_Sources#Victoria

And 'Parks on hteAir' looks to be copyright - bottom of their pages
They state "We are the sole owners of the information collected on this site. We will not sell or rent this information to anyone."

I don't see this on the Aust Data Soces page ... so is this a copyright breach???

You can view any ones edits and what they report as the source or sources...

eg
@Natiso/history#map=9/-32.844/151.627&layers=Y

@Warin61/history#map=6/-38.12/161.24&layers=Y

You have to click through to each changeset to check the source. In NSW I use the DCS Base Map, DCS Imagery, DCS is good for location accuracy .. Esri Imagery too, this is more upto date but can be offset location wise.

You can do with a little help?

Multipolygon relations are about the hardest thing. Some boundaries can be seen in the DCS Base Map. Most (all?) have been entered using downloaded data. Your best leaving these alone though some accidents do happen (humans do this).
If you have questions .. ask. The answers may not happen fast but they will come.

Oh I spotted some track tht you had entered .. is t was close to making a connection to another track but missed. I connected it . While these look fine on a map routers will see the gap and not route across it. If I see it again I'll let you know so you can see it for yourself..

Not all of Mount White Station is a meadow.

Hi
The relation/16692137 pedestrian .. that is not the way it is done. This has shared segments on the outer ways...

There should be an outer way or more than one. But they should not share segments. Then there can be inner ways to make holes in the area.

HI
The guide is one feature = one OSM entry

So one way for the roof, layer=1
and another way for the hall?

I have deleted the relation and tagged the outer way for the building footprint.

relation/17064124
Stops in wrong order... Syd Metro West from Hunter St ... but first stop is Westmead .. and exit only.

This and 2 previous changesets partly reverted to maintain the National Park boundary.
Leave the National Park boundary alone.

Thais and 2 past changesets part Reverted.
Leave the National Park Boundary alone.

Brisbane Water National Park boundary again set back to correct location.

Water ways simplified - max error 1 m

You have once again modified the boundary of the national park!!!!!!!!!!!!!!!!!!!!!
