[Talk-us] Rural US: Correcting Original TIGER Imported Ways

How many of the TIGER imported streets are still untouched? Looking at
typical urban area with a high number of OSM contributors the your answer
might be very few. Seattle for example only has one street left, and
unnamed street in the far south of Seattle. King County, just under 6,000
sq km, has 292 untouched ways. Extrapolating the results to Washington
State, with 39 counties, you expect to see somewhere around 11,000
untouched ways. It's almost three times that number.

Washington State today has over 30,000 untouched highway=residential, far
more than what you would might expect from looking at King County. Many of
the untouched ways are located in areas known for timber harvest, most
likely forest service roads (at best highway=unclassified, or
highway=tracks, or not even there) and many others are service roads to
farms and homes.

Because King County has by far the largest population of active mappers, it
has touched just about every street in the county. Even the more remote
areas of eastern King County which is popular with hikers.

Utah, a far less populated state has over 7,500 untouched ways. (But an
absolutely gorgeous state, second only to Washington State 😀)

Western states may be more susceptible because of the number of forest
service roads. All states likely have the problem of ways classified as
residential when they should be service roads.

Martijn van Exel and I have created a couple of Maproulette tasks to fix
these ways. It's dangerous to leave them. Having a way classified as
residential when they are likely 4WD tracks in the mountain isn't safe. We
don't want some unsuspecting family out on a Sunday drive to get stranded.
If you do work on the tasks be careful not to just delete ways in the
forest as I was reminded recently. They may be used by hikers and hunters.
Correct the highway classification and align the with the imagery. Consider
using Strava heatmaps to assist tracing the ways.

If you want to help out, jump on one of the tasks below.
Utah: http://maproulette.org/mr3/challenge/2867 (Your chance to try the
beta version of Maproulette 3)
Washington: http://maproulette.org/map/2871 (It doesn't show up when
searching for challenges for reasons that I can't explain)

Does your state have a problem? Run the following overpass query to find
https://overpass-turbo.eu/s/w74 - just replace "Washington"  Need help
creating a Maproulette Challenge - just ask.

There is one other way to help in a big way. Recruit mappers in rural
areas. Have recommendations on who to target and how to get in touch -
share them. Have some success stories, tell us how you accomplished it.
