Errr ... highway=cycleway is not correct.

Use hightway=path (or track if wide enough to take a car/4WD) and add mtb=yes and/or bicycle=yes. You could even use a route relation ..
However .. read osm.wiki/Mountain_biking

Note: Best to respond to the questions you have been asked.

I have added a few details - tower + buildings at the top of the hill, parking area western end, expanded the parking node to an area eastern end, and a building just out of it.. I think this should be building=roof, layer=1 ... and a node inside it with tourism=information, information=board or map ... My edits usually contain a source tag saying where I got it from ... take a look and see what you think.

Hi,
What is the source of these names?

way/354530546 appears to be a private plantation, Removed relation referring to this single relation and added tags landuse=forest, note=possibly a private plantation possibly Nanagrve Station.

Sections of the BNT are private, the tags horse=yes,foot=yes, bicycle=yes on the relation are not correct for all of the BNT. Access would be best placed on the ways as they vary, not on this relation.

OK, I'll go ahead and delete it then.

Hartley Public School (node/3287366361) is not on the LPI Base Map nor is it listed on the NSW Dept of Education website. On the LPI Base Map in that location is a park, Bush Fire brigade and a residence. Made into a note, while adding the other features.

I use JOSM.
According to the history of way/174606310 displayed using JOSM the width was set to 4 on 5/8/12 at 9.01 pm. It was then changed by this changeset 30/7/13 10.29 pm
I have confirmed this using http://osmhv.openstreetmap.de/changeset.jsp?id=17152326+

You have set the width of Wheelbarrow ridge road to 1 ... that is 1 meter width .. you cannot get a car down a 1 meter wide road... reset back to 4 as it was before you changed it.

Hi,
You have marked way/196266984 as noname=yes ... if you zoom in it has a name. I have corrected it.

Hi,
Way: 57690476 tagged sport=tennis .. has no physical tag/s. Appears to be redundant as the individual tennis courts are mapped.
I have added surface=paved to these individual courts and added 2 netball courts.

Hi
What does 'trail_visibility_1=path' mean?
you already have 'trail_visibility=good' on Way: Ridgemont Avenue Fire Trail (384931687)

Hi
navigationaid= rather than naviagationaid

Hi,
I am entering some tracks for the Strava Cycling heat map. Your entered way/420021676 is part of this .. but it has no tags. I have tagged it as highway=unclassified. It could do with some more - surface=unpaved? source=?

Goodo.
While adding new stuff is what motivates me, 'housekeeping' makes the map work better. I have a few of my own things to 'fix up' too.

Hi,
Way: Old Wentworth Road (432825812) you have as access private .. yet the council map lists it .. see http://www.wentworth.nsw.gov.au/f.ashx/map/Rural-Roads-Map.pdf
It also appears on the LPI Base map.
So access is private?

GNB has some statement of open source? Not fussed.
However the GNB 'rural place' is used for both inhabitabited places and uninhabited places! It is not a 'good' description. What attracted my attention to this was the use of neighborhood for places inside the Blue Mountains NP that have never been inhabited.

Relation (361693) is not closed..

Bing used to determine a boundary ?

You have a lot of these ... and I don't think you are using bing as the source for these changes.

Tucklan ... while the council and post office may not regard it as a hamlet, I'd not think of it as a neighborhood either. I think in OSM terms .. hamlet.
