How many more years must I wait, then, before they will become visible

<http://openstreetmap.org>? If it hadn't been a couple or three years
already, I'd be more patient. A New Yorker would find it astonishing
not to see the Adirondack Park, which occupies about a sixth of the
land area of the state, but if it were not mistagged 'national park'
there would be nothing to trigger its rendering. The smaller state
parks, state forests, and similar reserves likewise would likewise
have no attributes visible to the renderer.
What exactly are you waiting for? the magic map fairies to read the
tagging list and think "hmm - request for a new rendering of US Parks,
must set some time aside for that" :-)
It'd be nice to be able to customise the tile layers easily on osm.org,
but the only reason that it isn't is that no one has sat down and
written the code yet. However, it is possible to use other tile layers
with a bit of browser trickery:
http://wiki.openstreetmap.org/wiki/User:SomeoneElse/Your_tiles_from_osm.org
. If you're not in a position to submit changes to osm.org yourself
(and I'm certainly not) you could perhaps try bribing potential
developers with donations, charitable or otherwise :)
With regard to "what gets rendered at what scale" I'd agree that there
is an issue with the styles on osm.org when showing "outdoor" features.
The cycle map does probably the best job around e.g.
http://www.openstreetmap.org/#map=13/36.4749/-121.2047 (just to pick
somewhere I'm familiar with and is fairly path-complete) but it's not
ideal. Again, however, the reason why a style suited to outdoor areas
especially in the US hasn't appeared is that no-one has yet created one.
However, it's really not _that_ difficult to tweak a version of OSM's
standard map style (or another one) to both display existing features
slightly differently and to display new features.
An example of the latter is in a lua script that I use for a local OSM
style here:
https://github.com/SomeoneElseOSM/SomeoneElse-style/blob/master/style.lua#L251
An example of "changing the zoom level at which something appears" is at:
https://github.com/SomeoneElseOSM/openstreetmap-carto-AJT/blob/master/landcover.mss#L474
If you can count brackets and change numbers to higher or lower values,
you're mostly there!
Someone did ask over at the issue list for the standard style "how do I
create a map style"
https://github.com/gravitystorm/openstreetmap-carto/issues/2246
whilst the question wasn't really ontopic there, the answer I gave
applies here too I think.
Cheers,
Andy
