That does make sense. sorry for making abit of a mess with the residential sections. My goal is to clean up the natural wood area around the NP, so it is more acurate.

Ok thats fair. In my recent edit i have taken the waters edge of woy woy bay and waterfall bay back to the original edge using the DCS Base Map and have left the National park boundary to what was reverted. I think this is correct now?

I see. That is some great advice. I really appreciate your help and thankyou for your patience. 🙂 I am really finding it interesting contributing to osm and i want to be as accurate as possible. Would you say the boundary is now fixed or did i mess it up abit? and When correcting the boundary do you use bing aerial image also or just DCS Base Map?

Ok cool, my apologies for stuffing up the boundary and appreciate the advice. I am new to osm.

With what information are you determining the national park boundary?

Thats fair.

Thats fair. my apologies for that. I was using the NSW base map, but i think the arial images is best. Is that what you use for edits?
