Hi

These roads are not connected - and they should be.
way/662371243 and way/172946484

Might be worth while keeping an eye on

Hi,
Welcome to OSM.

Some hints.
Relation outer ways should not touch - the building touch in this instance. I would make each building a simple way - no relation. Each building is probably an individual height so they will need to be separate anyway.

The school. As a node is the basic first step. Then it can become an area - that would surround the buildings and include parking, playgrounds, sports areas. Arrr but the school is already an area - includes the Primary School see way/514096660#map=17/-43.02413/147.04771. That could be edited to exclude the primary school and then make a new way for it.

That is what I think. I'll leave it to you to contemplate.

Vicinity Centres...
Tagged as a building

But also tagged as an office?

So what are is it?
A building - leave the office tag off
An office .. leave off the building tags.

OSM guide is one feature - one OSM entry.
Suggest you leave the building entry .. remove the office tag
Make a new node for the office and add its details there.
If the building is for offices ... then building=office - see the OSMwiki building=*#Commercial

Still many problems here.

Sean .. look at https://tools.geofabrik.de/osmi/?view=areas&lon=115.74092&lat=-32.53596&zoom=16&opacity=0.82

Try to fix these problems.
way/655517428 has no tag to say what it is.

For me and the others the simplest thing to do is delete the lot - leaving the shops. This won't change the map as the things that would be deleted are not rendering anyway.

Hi,
Relation outer ways should not touch.
In this instance there is no need to make a relation. A simple outer way covering the entire tree area will do the job. Fixed.

This changeset has effected a local reserve, the retail area ... Reverted.

Hi,
Welcome to OSM.
I have retagged the Synthonia Sports Grounds as a landuse=recreation_ground, the entire area is not a pitch. I have added 1 sports pitch as an example. I cannot see the other sports pitches well enough so have left it there.
Hope that helps.

Hi,
This looks to me more like a leisure=recreation_ground rather than stadium (substantial tiered seating).

Hi,

You have some netball courts with sport=netball:soccer .. they are a bit small for soccer and lack goal posts etc .. Why do you think they include soccer?

Hi,

The soccer courts 1 & 2 look to be netball courts ... using Ersi Imagery Clarity.

Hi,
The Portsmouth Grammar School Playing Fields relation - I have deleted one of them and tried to make the remaining one 'good'.
You are much more local than I am .. take a look at what I have done and change it to suit.

I have added some sports details to the pitches - that is my interest here .. I simply found the 2 relations for the one thing, both a bit strange.

No problem... just letting you know in case I stuffed something up..

Hi,
There relation .. have been deleted. They did not form closed ways - that is an area.

Number 111 is not the Post Office, it was the Post Office when it was built and has a sandstone entry that says 'Post Office'. Hence the errors that keep occurring :) If you knock on their door they are very annoyed about being constantly asked for postal stuff. Why they don't put a small sign up is beyond me.

Number 109 is correctly marked as the Post office.

Err .. correction to my above comment! Should read
The Mt Victoria Post Office is at Number 109 NOT 111! Number 111 was constructed as the post office but is not the present post office nor has it been for many years.
Please correct your entry.

Base Map appears to be in copyright contradiction?!

Hi
You add the tag of grass to Way: 142095396 which was/is tagged as a park. Not all of this park is grass .. so I have removed the tag for grass.

way/655517707 had duplicated nodes - fixed. Might lead to other problems elsewhere.

And no tags as to what it is... ??? parking area?
