problem is that we end up inconsistent in that there are routes with<br>
prefixes<br>
and routes w/o prefixes. looking at it from the viewpoint of a data consumer<br>
which is a program, this means headaches in developing parsers. Mapnik<br>
doesn't<br>
have a problem, it just renders whatever is in the ref tag, but other data<br>
consumers may encounter issues.<br>
<br>
what you're really making a case for is a California specific style sheet<br>
for current mapnik, or for completing the shield project which would<br>
take care of all these issues in a pretty conclusive way. states are all<br>
different; in Florida where i grew up, prefixing state routes with SR is<br>
very natural. in NY where i live now, prefixing state routes with NY is<br>
something familiar to all New York residents (or at least, upstaters.)<br>
<br>
one thing that is important to remember that there are data consumers<br>
beyond the map displayed on <a href="http://www.openstreetmap.org" target="_blank">www.openstreetmap.org</a>. we say that you<br>
should not tag for the renderer. i suggest that this formulation is<br>
incorrect;<br>
we need to tag taking into account the vast ecosystem of renderers<br>
and other data consumers that exist out there. so don't tag for one<br>
specific renderer (aka mapnik.) tag for all of them as best as you can.<br>
turn relations and speed limits for routers, include POIs that mapnik<br>
doesn't display by default but which OsmAnd can, and so forth.<br>
