Mysterious routing error in non-production data #81

Closed danrademacher closed 5 years ago

danrademacher commented 6 years ago

Prepping data update form ecg_route_lines to ecg_route_lines_prod

And there's some error in this section of the route: https://map.greenway.org/?loc=12,32.79478,-79.90854&route=32.77612,-79.92711,32.82586,-79.81822 works fine there image

Locally after changing table ref in config.js to ecg_route_lines http://localhost:8007/?loc=13,32.81108,-79.87767&route=32.79629,-79.89077,32.82586,-79.81822 image

I have inspected each segment in production vs edit tables. Production has some additional segments not in the same area in the edited database, but most differences appear to be improvements (simplification, removing extraneous southbound line running parallel to both line, etc.

Not sure what is causing the router to break there. Works north to south otherwise.

Will look with fresh eyes on monday

An even shorter segment: http://localhost:8007/?loc=13,32.79235,-79.86246&route=32.79629,-79.89077,32.78840,-79.78781

And shorter: http://localhost:8007/?loc=14,32.77991,-79.87528&route=32.79629,-79.89077,32.76353,-79.83662 image

smallest segment I can find that fails: /?loc=16,32.78985,-79.88143&route=32.79492,-79.88307,32.78479,-79.87399 image

image http://localhost:8888/?loc=16,32.79412,-79.88683&route=32.79684,-79.88803,32.79132,-79.88007

Something about this turn: image http://localhost:8888/?loc=18,32.79054,-79.88031&route=32.79132,-79.88007,32.78975,-79.87910

This works: http://localhost:8888/?loc=16,32.78653,-79.87779&route=32.78975,-79.87910,32.78319,-79.86934 image

Noticed in that last shot that something seemed off in the order of the blue chosen route lines. Redrew Church St. NOw it works

Reopening to see if we can assess cause for future reference
