tl;dr - I’m interested in getting more surfing-centric tagging into

what would be appropriate. In an analogous way to how cycling is
treated, along with trail running, my own sports of choice.
Hi, welcome.
The long story:
My teenage son is quite the avid bodyboarder, and we just got back
from at weekend at the Aussie national championships in Port
Macquarie… Which leads into me realising as I try to wrap my head
around the sport, that there’s very little surfing-centric content in
OSM. Doubly strange in Australia. And we’re homeschooling, so… hello
geography, cartography, environment, etc, lessons.
I printed out a map of our local (Newcastle) beaches using
fieldpapers.org <http://fieldpapers.org>, and got him to draw them in,
then uploaded it. The FP page is here:
https://fieldpapers.org/snapshots/ubcffu8v but that doesn’t seem to
display the output properly, download the geotiff to view. Here’s the
map tiles of it:

I looked up what was already present in OSM, and it centres on the tag
sport=surfing, https://wiki.openstreetmap.org/wiki/Tag:sport%3Dsurfing
According to the overpass query https://overpass-turbo.eu/s/1lgi it is
already applied to a few surf breaks (sometimes not very precisely),
surf shops, venues, and learn-to-surf organisations. I will explore
more thoroughly.
Mostly land based things. Can you give a few examples?
I found this one,
https://www.openstreetmap.org/way/1009395310
looks to be both surfing sand swimming...
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?
There are those that say yes to a formal proposal, others nay.
You may have noticed my Hills Hoist thing.. I raised it here to see what
reaction I got and to seek ideas. I have now raised it on the tagging
group for more of an international view and will raise it on the russian
wiki page on the 'umbrella' tag.
I would think you may get some feed back here to start with.. then raise
it on the talk page
https://wiki.openstreetmap.org/wiki/Talk:Tag:sport%3Dsurfing
As the break would be a water feature I'd use a water tag
waterway=surf_break ??? That could be a way where the break first occurs
.. possibly sub tags such as break=left/right/* This would be the
physical feature for use with sport=surfing...
Just my idea.. you may have more/different?
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?
The surf break may be visible on some of the satellite imagery. Mapbox
off Tamarama Beach, Sydney looks large.
