Hi everybody
It seems a not uncommon practice to for place names to be markedin huge
writing (on a hillside). They're very visible and have, I feel, some
cartographic value.
Below is the start of a new tagging proposal. I thought I'd throw it
open to the list first before going to all the effort of putting
something useless on the OSM Wiki
<http://wiki.openstreetmap.org/wiki/Proposed_features>. This is just a
startand I'll probably add more detail and examples as time allows. I
haven't done much tagging of these objects because I've only just
figured out what to tag them with.
*Tagging*
I propose placing a way over the name from left to right (of the word,
so if it's upside down in you editor...) then tagging it with
tourism=ground_sign name=*. That would probably be sufficient for the
River

<http://aerial.openstreetmap.org.za/?zoom=18&layers=B0&lat=-34.1142101&lon=21.2524555>
example. For the Oord / Resort
<http://aerial.openstreetmap.org.za/?zoom=18&layers=B0&lat=-30.5875051&lon=25.5080875>
example,the way would simply contain multiple nodes to make it go around
the corner.
Often these the signs are pictures, or written in a weird font that a
renderer like Mapnik can't do justice to. For these I propose tracing
what you see on the ground and simply leaving the name=* tag blank. You
can still include the name by putting the letters you draw into a
relation and tagging that with name=* (all the better to be able to
search for it). The markings near Wakkerstroom
<http://aerial.openstreetmap.org.za/?zoom=18&layers=B0&lat=-27.3728169&lon=30.1580294>
might require this method.
Filled shapes can be created by using closed ways and multipolygon
relations. I haven't come across such examples, but I'm sure they're
out there.
*Supplementary tags*
* width=* to specify how wide a line should be drawn
* color=* (or colour=?) to specify what you think it specifies
* surface=* or something similar to say what it's made of.
*Examples*
* Riversdale near guess where:
http://aerial.openstreetmap.org.za/?zoom=18&layers=B0&lat=-34.1142101&lon=21.2524555
* Oord/Resort marking near Gariep Dam:
http://aerial.openstreetmap.org.za/?zoom=18&layers=B0&lat=-30.5875051&lon=25.5080875
* Voortrekker markings near Wakkerstroom:
http://aerial.openstreetmap.org.za/?zoom=18&layers=B0&lat=-27.3728169&lon=30.1580294
I'm curious if these appear anywhere else in the world, or if it's just
a local thing. There are other considerations too, like are
/ground_sign/ and /tourism/ the best tag names to use(think about
highway=road and highway=unclassified for an OSM newbie)
What'd'ya think about that?
Later
Glen
