The source you use - LPI Imagery shows that part of the Wianamatta Parkway is under construction. I have changed this section back.

Why do you think these roads are any thing other than 'unclassified'???
The LPI Base Map suggests they are not secondary/tertiary.

No response. Deleted.

1) OSM has very strict rules about the source of information entered.

What is the source of this information?

2) The changeset comment makes no sense. What is it referring too?

Arr... error.
Original entry for this was from gdal .. I have deleted some of his entries... I think they are illegal 'camp sites' used by self contained RVers for over night stops. Someone travelling in Africa wants to have some indication of these kind of 'stops'. Where I think I got 'my' additions from was a web search that got me that rivierdal one in Tumut. I am up dating that now.

Hi,
node/2440941742, name=camel ... what is it??

Hi
Adding a name to a node and nothing else does not add anything to the map. I take it the name 'water tank is a simple description, not the name. So I have deleted that .
I have made a circular closed way and added the tags man_made=storage_tank, content=water.
Please make better entries.

HI,
node/3011855842 has name only ... needs tags to say what it is...

There are a number of these .. take a look at
https://tools.geofabrik.de/osmi/?view=tagging&lon=145.93448&lat=-41.06283&zoom=11&opacity=0.76&overlays=nodes_with_empty_k,ways_with_empty_k,nodes_with_empty_v,ways_with_empty_v,node_tags_with_whitespace,way_tags_with_whitespace,node_with_unusual_char,way_with_unusual_char,node_with_short_or_long_key,way_with_short_or_long_key,nonop_confusion_on_nodes,nonop_confusion_on_ways,no_feature_tag_nodes,no_feature_tag_ways,ways_without_tags

Hi,
node/3106811025 has only a name. That does no good, it needs tags that say what it is.

Hi,

What is node/943241868 .. Daniels???? There are no other tag other than the name.

Agreed, done.. though what I did was changed it to a locality with 'inspiration point' moved some distance from the road. As per the Base and Topo maps

Hi,

The tag construction=yes is not correct.
Highway=construction with construction=residential is the way to go.

Next.
The roads that connect to this roundabout should be tagged one way. And the bus routes need to be edited. And the suburban admin. boundaries edited as well..

Mapping gets complex where details are added. Keep going, but learn as you go.

Hi,

The toilets would be inside the building, not attached to the building wall? I have disconnected them and the drinking water from the walls so they can be moved without trouble.

Note. The buildings look to me to be separate. I have taken there outline from the roof .. then moved that down to the ground. Reason why this is important is that a multipolygon relation cannot have the outer ways touching.

Hi,

What is "Phoenix Trail sign"? It is on a single node, probably in OSM speak a tourist=information, information=sign/map/or something else?

Hi,
Sorry but objects with only a name do not make any kind of sense.

What is 'visual arts 1"?
What is 'TLC'?

etc.
Suggest finding an appropriate physical tag for these features.

Remove the node - it is a duplication of the way...

I came across them using https://tools.geofabrik.de/osmi/?view=areas&lon=147.21387&lat=-31.88315&zoom=6

It is one of the quality tools for OSM. It is not free of its own errors... but it does a fair job. Do note the date when it was updated .. runs behind.

Hi,
Problems... I'll use Castle Hill Station as an example.
At the moment there are 5 Castle Hill Stations.. there should only be one. I'd chose one of the nodes at this stage and leave that as the station. Then it should be tagged railway=construction, construction=station.

The 3 buildings .. should be tagged building=construction, construction=transportation.

When things are complected the construction=* gets deleted and the *=construction gets whatever was the value in construction=*

------------
Ideally the station should be a single enclosing way that encompass all the station. But a node will do for now.

Hi
When you change highway=construction to something else .. the tag construction=* needs to be deleted .. otherwise it is confusing.

?
I stated what is on the wiki (that can be wrong!). Your free to disagree with it, I do on occasion (e.g landuse=grass grrr).

If I delete these .. will there be any effect on a map/app? While deletion looses this information, if it is not used then what have we lost?

Nothing personal. Just trying to tidy up things that are not being rendered, either by deletion or adding tags that may get them used.
