General Web Design Discussion / Re: Overlay map color schemes

« Last post by jtstill on January 21, 2025, 09:17:29 am »

For what it’s worth, it’s possible at the moment for an average user like me to see unhighlighted untraveled sections and keep what I have travelled in view, if I’m willing to dig a little: I just go to Inspect > Sources > updateConnectionColors() and update the opacity variable in that function to “1*highlight” instead of the default “0.3 + 0.55*highlight”, and then it applies the new opacity variable once I toggle the highlight options dropdown. Of course, I’d also love to see a front end way to do this, since I have to reapply those changes every time I reload the page or change the region (and the site still loads ALL segments, even the unhighlighted ones, so I can’t really do something like get the entire USA in view and then change the opacity settings, since it’ll never load. It’d be great to find a way to not even load untraveled segments so I can see the full extent of my personal travels)

Updates to Highway Data / Re: CA: US 395 relocation west of Death Valley

« Last post by oscar on January 21, 2025, 12:34:15 am »

US 395 Business signage has been posted for part of old US 395 in the Olancha area, apparently including part of the old road north of Olancha not incorporated in the recent western extension of CA 190. However, it's unclear how much more of the old road is signed or otherwise designated as Business US 395. It might extend to a temporary connector road at Lake Street in Cartago, which is being replaced with a short new road to link the business route to the US 395 mainline.

I'm interested in similar things.  I'd like to be able to do things like show tables/charts of clinched routes/distances over time and make animations of a user's travels on maps over time.  All possible, but it takes time that is very limited, at least for me to be able to do it.

How would that take into account administrative corrections and changes in data?  I've been known to adjust what I have marked clinched as I reflect on past travels and even what I count as a clinch (I've waffled on whether to count part of US 31/280 in Birmingham a couple times, for example).  And some major changes in data could be a challenge (such as US 301 in Delaware, or the division of France).

I'd want to get more user feedback about this before changing that number (currently 0.3).

I was annoyed by that for years....

You can see what it would look like if opacity gets changed to 0.1 if you use the tmstage.teresco.org server, where I just changed it.

It's great! However, it's identical to the production server. Have you changed it too?

I remember what annoyed me. Switch to "Color by concurrencies" and "Highlight None". The overlap of two blue lines at the intersecting wp is very dark. It sometimes looks like broken concurrency from lower zoom. See attached.

I have noticed that the blue lines tend to have less contrast between segments that are highlighted and those that aren't than the other colors do, especially when zoomed out.  In fact, If I show my travels on usai to people who aren't roadgeeks, they'll assume that I've clinched the whole system because the contrast is low enough they can't tell the difference.

I'd like to be able to check my own stats to see how much I added to my inventory, too.

You just have to open two log files under https://travelmapping.net/updates/

Code: [Select]

2024-01-01: 67,621.21 miles active+preview
2025-01-01: 77,962.87 miles active+preview
Total 2024: 10,341.66 miles active+preview
Of course, I'd love to see functionality doing the trick on the front end....

General Web Design Discussion / Re: What are mileages based on?

« Last post by Jim on January 20, 2025, 05:34:52 am »

TM distances are approximate.  They are straight line distances between consecutive waypoints multiplied by 1.02112, though all of the trig is in there to compute them on a sphere not a plane.  I don't know why that particular number.  It was inherited when TM was created using the data (and that distance function) from the old CHM project.  If you look at TM route lengths vs. official sources that report lengths, they will be a little longer or shorter, depending on how straight or curvy the road is.

I hope the lengths of segments aren't based on the lengths of the straight lines that are used to draw the segments. Are these something that are measured using some external tool like Google Maps, and then entered manually as attributes of each segment?

I'm definitely interested in a way to track user histories, and I am sure the log files will be helpful to build such a thing.  As it stands, we can do Unix diffs, the equivalent of Git change logs, on the text files.  But this is not available to regular users directly, and as michih points out, changes in the logs occur not only for your new travels but as highway data is updated and expanded.

Here's what I'm most interested in at the moment. Some of the bigshots around here like to tell us they drove another million miles of new road last year. I'd like to be able to check my own stats to see how much I added to my inventory, too. I'll never be in oscar's or mapcat's league, but it's still interesting information, at least to me. I can see how I can do it in several steps, but, since I know how to use git and GitHub, it would be easier just to bring up the appropriate commits without cross-referencing, or even do a git diff. But this means I wouldn't be interested in changes to my stats as a result of changes to the underlying databases, and at least in the US those changes would likely have only a tiny affect on my stats, since the database is pretty much complete.
