Re: [Talk-us] JOSM zoom limits per server solved (fixes Tiger grey overlay )
I knew about the max zoom setting but for some reason never thought about
applying it to the TIGER tiles to fix the grey

I've been using Remap-a-tron to fix up US roads. I use both the Bing
imagery and the TIGER 2012 tiles overlaid, and it makes it really
useful.
However, I've been frustrated that I can pretty far in with the Bing
images, but if I go too far, the Tiger (normally transparent) tiles turn
grey and obscure the Bing images. I've been continually turning off and
back on the Tiger layer, which is a bit annoying after a while.
JOSM has an easy limit in the Preferences for the maximum zoom, but it
affects everything. I set it to 19, and then I did not get the grey
boxes from Tiger, but did not get the higher detailed photos from Bing
either.
As it turns out, JOSM does have a max-zoom per tile server feature; it
just is not obvious or clearly documented that I could find.
You can enter it as part of the TMS url like this:
tms[19]:http://{switch:a,b,c}.
tile.openstreetmap.us/tiger2012_roads/{zoom}/{x}/{y}.png
The number 19, right up front, says that the maximum zoom to use for
this layer is 19. This solved the whole thing for me.
I also found that if you go into Josm preferences in expert mode, and
dig and dig and dig into the imagery providers entries, this is labeled
as max-zoom. Too bad it isn't easier to find.
Anyways, hope this helps others too.

Re: [Talk-us] JOSM zoom limits per server solved (fixes Tiger grey overlay )
I also found there is a minimum zoom also. Put it in the url as min,max like
tms[16,19]:http://...
Fixes the grey tiles when I zoom back out.

Re: [Talk-us] JOSM zoom limits per server solved (fixes Tiger grey overlay )
The root cause if you will, is that TileStache doesn't support 404ing
instead of grey tiles when a request falls out of the specified bounds. If
someone wants to code that up and submit a pull request, I would much
rather use that.

Re: [Talk-us] Schizophrenic highway
It intersects with a major road atonly one end. After the discussion, I'm sticking with my original primary road code. Maybe some day they will finish it, but right now it's most just a two-lane highway. We'll see if the next iteration of Bing photos shows that they are working on it again. At this point, they don't seem to be doing anything to finish the work that was started.

In two spots in a 25-mile stretch, intersections have been turned into cloverleafs and the highway divided. In other locations, roads that used to intersect US 50 have been turned into overpasses. There are even a couple of bridges for a second lane but no evidence of any construction work actually to build that lane. The vast majority of the highway is still two-lane blacktop.         So how does one tag this, as a primary road that just has a couple of cloverleafs? Probably. Without looking at aerial photography, I'd say it sounds like a super-2, or at least a two-lane expressway; the tags expressway=yes an/or motorroad=yes might be applicable. Also, if the ends of this improved section are near other major roads, then highway=trunk might make sense. Sorry for the uncertain reply but it's not convenient to closely inspect these things on my phone.

Re: [Talk-us] JOSM zoom limits per server solved (fixes Tiger grey overlay )
Not to get into the coding as I have no idea how it is handled, but better
to not offer a 404 page, but to keep the min/max zoom tile as the reply in
this case.
Ie if asking for zoom 20+ return with zoom 19 instead. More of a redirect
instead of 404 if zoom is out of bounds.
One possibility to slightly abuse the zoom limits... tms[19,19]:http://...
probably fine for lots of stuff as you would probably end up at that level
anyhow.
Could we get just 2 zoom levels? say 16 and 19?
