What's happened to the golf course?

Depends on what you mean by the basemap. The meta data is for the underlying data so if you extract the data rather than tracing then it's up-to-date to within 10 days. I don't know how often the tiles that get served for the visual map are re-rendered so it may take some time for it to show up on this.

The other thing is that unless the property boundary is re-surveyed for some reason what's in the database will be what was digitised from the paper map.

1. After typing in my comment the other day I was pondering why the boundaries are that way at Barrenjoey and I've realised that the boundary follows the low tide mark. (Also means that the lighthouse reserve must of had a combination of high/low tide boundaries).

2. I'd also previously looked up the metadata and discovered that a lot of the coastline and river data had been digitised from old maps. Which is the reason why I don't get too worried about it. I suspect that the error between the coastline and the data is usually more than the difference between high/low mean water. Also trying to visually identify these from an single aerial view is also going to be hard.

3. The road boundaries are a common feature. The original subdivision of the land included reserves for roads. Where the surrounding land is also owned by the Crown they seem to not particularly care so the road winds in and out of the reserve. But the National park is defined as being lot i of DP n + lot j of DP m etc and the road reserve itself is not in the park. You can see these all over the place including some where there is a "paper road" with nothing on the ground.

Hey! Someone found a use for my good-ol friend Mainland Australia.

I put the suburb boundary in before we had access to the LPI data and I was using best guess as to what the ABS boundaries were on the ground, hence using the coastline.

Interestingly the NPWS boundary isn't consistent with the cadastre around the coastline, which is a bit odd because the property boundaries would define what was gazetted as the park boundary. But it does line up exactly with the suburb and LGA boundaries.

As to the southern boundary it is currently correctly aligned with the cadastre so unless you happen to have found the survey pegs I'd say that's the best available information.

Coastline boundaries on the other hand are so vague (LPI has two different interpretations available) I'd be happy to snap it to the coastline. Trying to figure out if it's supposed to be mean high or low water would require going back and trying to find the original designation of the lighthouse reserve.

Somehow I don't think that way/46856278 is a residential road. More likely highway=unclassified

Roads on military bases should be tagged access=no.

No level as it not a thing that you need to map. The unincorporated areas of South Australia are the bits inside the admin_level 4 boundary but not inside an admin_level 6 boundary.

That may all be true, but this area is not administrated under the Local Government Act so therefore it's not a council and not admin_level 6.

Err... by definition unincorporated areas don't need a admin_level=6 boundary.

Actually fixing note #737131

Yeap, constant problem everywhere you've got a river or coastline.

Apparently in OSM land the beach only goes down to the MHWMS.

Any boundary that's based on property boundaries will generally be referred to MHWM (which in OSM land is in the sea). But complicated by the fact that the property boundary is where the surveyor measured it and doesn't move until there is some legal reason to re-establish the boundary at which point there are a whole bunch of rules that determine where it has to moved to.

Lastly in NSW the council has control down to the low water mark (unless they have been gazetted other wise eg: only to the boundary of some DP and lot).

As a result we've tended to just import the boundaries from LPI and left them where they are.

Turn out that the original import of the NP boundary left out the southern block. I've done a refresh from the LPI data.

Err, I think you'll find that the correct capitalisation is "Westlink" not "WestLink".

Thank you.

Odd, they don't line up with the Bing imagery in JOSM. Guess it's something to do with Potlash.

If you're doing mapping in NSW we have access to the NSW LPI Imagery, which is clearer and more accurate. Not sure how you go about accessing this in Piotlash but the URL is:

Hi,

You appear to have realigned some of the streets eg:
node/212286301#map=19/-34.84228/148.91947
node/212286399#map=19/-34.84059/148.91798
node/212286544#map=19/-34.84183/148.91596

What source did you use for this? they don't appear to line up with any of the available aerial imagery.
