KY: Odd coloring on Bluegrass Parkway
« on: June 26, 2018, 10:25:40 am »
The segment of the Bluegrass Parkway between 21 and 25 is colored Blue (Tier 1) instead of Teal (Tier 2). The rest of the parkway appears to be correct.

Hm. A real-world example of confusion that can be caused by rendering multiple polylines of different colors atop one another.
https://github.com/TravelMapping/Web/issues/198

Magenta = blue + red; teal = blue + green; mix`em together and the red & green add together to make a lighter blue: 100,200,200 & 255,100,255 average out to 178,150,228, which isn't too far from the 100,100,255 of unclinched blue.

If you instead look at mapcat's mapview (he has this segment clinched), it's still a little blueish but more visibly teal compared to I-65 a bit to the west.

See https://github.com/TravelMapping/Web/issues/198 for information about a first attempt at a fix.

See https://github.com/TravelMapping/Web/issues/198 for the latest on the efficiency fix for this enhancement.  The cost of the current solution to this is small compared to the other costs of loading maps with lots of routes.

Please try out mapview on tmtest.teresco.org for now, and I plan to add this functionality to the production version soon.  Maps with many routes are still very slow, but the majority is DB lookup introduced for better ordering of route lists (https://github.com/TravelMapping/Web/issues/276).

The fix to draw concurrent segments only once is now live on the main site.

Is there a way to make the old process (drawing multiple lines for concurrencies) optional? I miss being able to detect concurrencies of different tiers in mapview.

Possibly, but I think the best way to find concurrencies (or non-concurrencies) is to load up the appropriate graph in HDX.

Sorry, I should have mentioned that I was planning a trip, not looking for errors.

Got it - I added an issue so I can look into it when I have a chance.
