Totally awesome there Jim!!  Thanks to it, I noticed we have a major problem with one of the PA State Highways with two points in an incorrect order.  I'll make a post about it in the old forums so we can fix it right away when we start doing that stuff.

For these regional maps only, would it be possible not to display the waypoints?

That is AWESOME.  Not quite as nice as the regular maps, but still wonderful to be able to see the maps at least in some form again.  I'm currently going over every state/province where I've clinched new roads since my last processed .list file at CHM.

I like.  Easier to zoom in and get a feel for what you missed.  (Though I had nabbed a few since 11/8/14 but was too lazy to send it - I'll get off my ass sooner rather than later  :sombrero:  )

I'm very excited about the newest enhancement to the draft highway browser, one that was always on my wish list in the old CHM project.  Now, if you specify a region and a username, you will get a Google Maps plot of all routes in that region, with the user's travels highlighted.  For example:

http://www.teresco.org/~terescoj/travelmapping/hbtest/?rg=MA&u=terescoj


1. My browser crashed the first time it tried to load. I had to restart it. Then the site worked.
2. Is there a way to turn on/off the markers? It's hard to see the road underneath.

There are tons of improvements that yesterday's new mapping feature needs, and turning on/off the markers is definitely one.  Once I fix the problem of inactive (unclinchable) segments greying out clinched segments by drawing right on top of them, that's likely next on the list.

Three improvements to the region-wide clinched mapping with Google Maps:
  • checkbox to hide markers
  • inactive systems now ignored to avoid overlaying unclinched over clinched segments
  • lines are narrower to improve visibility when maps zoomed out

  • lines are narrower to improve visibility when maps zoomed out

Another reason why inactive systems need to be ignored is that some of them have serious errors yet to be fixed by their maintainers. I know of a few in AK (major reroutes needed for AK 5 and one AK 10 segment) and at least two in CA (never-built -- not "relinquished" -- part of CA 39 between Azusa and La Habra, and CA 86 moved to and absorbing the former 86S). Those systems are inactive for a reason! Leave them undisplayed (or displayed separately from activated systems) until they're ready for prime time.

I'm back home from a long road trip, and will probably have more to add once I catch up on sleep.

Now that's just too cool.

One odd thing I note is that unclinched segments are sometimes but not always layered on top of clinched ones. See for example here:

Unclinched 298 is layered under clinched 481 (as, IMO, it should be), but unclinched 290 and 5/92 are layered over it.

I'm not seeing any particular pattern as to what goes over versus under. I even note that in cases where the same two routes cross multiple times, they don't necessarily maintain consistent layer order. My unclinched US 11 in VA is layering over my clinched I-81 in VA at almost all crossings... except the ones at exits 195 and 213. At those two spots US 11 is underneath.

I tried reloading a few times and it appears what goes over versus under remains consistent each time the map renders.

One odd thing I note is that unclinched segments are sometimes but not always layered on top of clinched ones. See for example here:

Rendering order is determined only (at this point) by the order in which the routes are added to the DB, which is from the systems.csv file.  That file is currently alphabetical by system code, with all active systems first then in-development systems (which are now ignored).  So, when there's an overlap, the one last alphabetically will take precedence.  In New York, usai routes go down first, usaif next, usany on top of those, then usaus, and finally usausb.  In a future production system, we'd do something more appropriate (clinched on top?  top-level systems on top?) or at least something intentional.

Thank you for working hard to push this project forward.

I (and I'm guessing others who enjoyed the CHM site) would like to know if this team has a tentative timeframe of when users will be able to submit .list (or whatever format) files. I expect it will take some time to get things working properly, but it looks like reasonable progress is being made. Not being a technical person, I can't guess whether the time to "completion" is being measures in weeks, months, or years.

Again, I thank you all for the effort and look forward to being to update my travels online once again.

The obvious solution is backwards from now - higher numbers are going to be less important, and more important systems come first.

This is excellent - I can clearly spot errors I've made on my list file this way, as I can see where stuff doesn't join up.

I know we had some notion of "tiers" in the old site and it probably makes sense to use those.  Maybe they should be put into the systems.csv file.

Jim:

I reviewed some of the errors in my log file. Most of the ones I can't figure out have one or both waypoints starting with *:

Waypoint label(s) not found in line: KY I-66FutBow 20(65) *OldCumPkwy
Waypoint label(s) not found in line: FL US98 US98BusPen_W *OldUS98PSJ_W
Waypoint label(s) not found in line: VA US221BusBed US221_S US221_N
Waypoint label(s) not found in line: NC US29 SC/NC *I-85(82)
Waypoint label(s) not found in line: PE TCHPEI NB/PE *StrRd_W
Waypoint label(s) not found in line: PE TCHPEI *ChuRd_E Fry
Waypoint label(s) not found in line: KY CumPkwy 1 *OldCumPkwy
Waypoint label(s) not found in line: NB NB175 *OldNB1_W *OldNB1_E
Waypoint label(s) not found in line: PE PE9 *OldPE1 PE2

The data I checked seems to show both of the waypoints in each line, but for some reason one or the other isn't recognized by the list file parser, and my hunch is that it's the one starting with *.

The other weird one is for VA US221BusBed. Somehow, it got a duplicate of the route file for VA US250BusChr (which is shown correctly in the draft HB).

We will also have to setup our own forum when we're ready to go so people can post error reports.  I'm happy to do that part as long as we want to stay with SMF since I know the most about that forum software.

Render unclinched first, layer 3 -> layer 1. Then render clinched segments, layer 3 -> layer 1.

Ignore the * when parsing waypoint labels, so whether "ChuRd_E" or "*ChuRd_E" is used, both will be recognized.

Makes sense.  I think I can make that happen next time I get back into the mapping code.  I think the same ordering will be used for the static maps.

Yes, I'll fix this.  I clearly misunderstood how the "*"s were supposed to be used.  Related: if someone's list includes a valid hidden label and includes the "+" in the label, should it match?

Edit: fixed for *'s - let me know if any such errors remain.

What are the *s for anyway? I've never used them myself.

Related: if someone's list includes a valid hidden label and includes the "+" in the label, should it match?

I don't think so? If a waypoint's label is hidden, it's probably because it's only for routing purposes and isn't really an entry/exit/intersection point.

Brian:  no timeline yet.  A web domain has been reserved, but the programmers (i.e. Jim and others) are still working out the code.

If you guys wouldn't mind I'd be happy to host it on my site. :) I'm already paying for a VPS anyway and I'd rather host as much stuff as I can.

They indicate a point that traffic used to be able to leave the route.  An example would be a closed interchange.  We'd put the * in front of it so people could still mark that they left he highway there.

My own list file includes a few entries using hidden labels, one of which includes the "+" (the hidden labels are used where there isn't a labeled waypoint where I need it). I'll remove the "+" for the new file I'm about to send you, but other people might have "+"s lurking in their list files too.

They indicate a point that traffic used to be able to leave the route.  An example would be a closed interchange.  We'd put the * in front of it so people could still mark that they left he highway there.

Perhaps more common is where a highway was substantially realigned, and * points indicate where the new alignment peels away from the old alignment, so people who traveled the route pre-realignment would have covered it only up to a peel-away point. That's what happened in most of the log file error entries quoted in one of my posts above (the other was a closed interchange).
