[talk-au] Mapping surf breaks

[Phil Wyatt]

Hi Folks,

 

It might also be good to see how current surf sites rate and classify breaks and try and incorporate common language in the tagging

Are there any concerns on me taking the idea and running with it? It would be good at least to flesh out the wiki page on what tags can or should be applied. I already have a spreadsheet from the grommie on the various attributes of a surf break (left and right waves, tide/swell/wind required). Does this require a formal proposal? 

 

My own pause relates to how even though surf breaks are physical locations (would be mapped as either areas or points), they are tied to underwater features and topography such as reefs, not necessarily visible from the surface. And so will rely heavily on local knowledge. But if not rendered by default, there’s no problem with that, right?

 

It would be great to see surf breaks better mapped!

 

I would suggest just start tagging ones you know well, invent your own tags, no proposal needed so you can be liberal with experimenting with the tags and how the features are represented. Over time I'd recommend documenting your tags on the wiki, if eventually into a proposal, to gain a more global point of view and consensus.

 

natural=surf_break

surf_break=* (beach, reef, shipwreck, etc)

sport=surfing

name=* if named

 

Points or areas should be good. Would linear ways make sense sometimes? Right hand side could indicate direction waves break?

As an avid surfer (Sydney region) and OSM contributor I love the sound of this!

 

Something I note that is missing on the wiki (https://wiki.openstreetmap.org/wiki/Tag:sport%3Dsurfing) is how to tag something when surfing isn't an option at a beach - the absence of `sport=surfing` on a beach node may just mean it hasn't been surveyed yet. Being able to query all surfable (or exclude non-surfable) beaches would be great for a road trip or choosing a campsite.

 

For example, Brighton-Le-Sands never has waves as it's in Botany Bay. `sport=none` wouldn't make sense as it's a great spot for windsurfing (and beach cricket etc :D). Is there space for a tag like `surfing=unsuitable` or `waves=minimal` to be added to a `natural=beach`?

 

If we could start over I'd advocate for natural=coastline on the land/sea border only, and natural=shoreline for other borders. Would it be safe to assume beaches along the sea/ocean edge are surf beaches and beaches along bays or harbours are not?

 

surfing=yes/no should act like the rest of the access tags, meaning are you allowed to surf or not, rather than is it any good for surfing.
