Hi all, this thread has deviated lots from the initial question about high water marks but on a broader level, it’s important to note that statewide maps like the NSW Base Map are not the basis for legal questions. Individual property title plans are. The statewide maps just give a good

I looked at the separation of park boundaries and coastlines down in Wilson's Prom a while ago and asked the #oceania discord at the time but never ended up changing anything. If you look at the legal definition of many national parks, their boundaries are defined by the high water mark. Since

Personally I'd prefer to snap them, it makes it easier for us to maintain, better for data consumers, and overall cleaner data. I speculate these departmental GIS teams are creating the boundaries from their own coastline datasets anyway, so why not just have them match OSM's coastline? I think
