Over the past few days I've been cleaning up a lot of Strava related user error reports. I've managed about 500 or so across the southern hemisphere; with a surprisingly high hit rate of actual issues.
One thing that has been quite obvious is that much of Latin America has a very active hiking and biking population; but a relatively poor routing experience.
There's two easy ways to help in mere minutes:
Keepright's Highway-Highway check
Look at the error, and decide if the two ways actually do join.
ID makes it quite easy to make a new junction, occasionally you might need to model a tunnel or bridge instead.
This is well suited to remote mapping; though imagery can be somewhat dated or misleading at times.
Strava's heatmap enabled error report tool
While you may not speak spanish or portugese, a lot of errors fall into the category of "there is a rural/unpaved road which is not traced"; and it's very obvious from GPS data. Google translate can help immensely in understanding the basics.
Why São Paulo?
I've opted for São Paulo as a good place to focus; as it's home to about 12-20 million people in the core/surrounding metro area - it's effectively the 3rd largest city in the world.
In particular with the keepright errors; it's plausible we can get to very few uncertain/unresolved issues in a reasonable amount of time.
This directly benefits anyone using Strava, OSMAnd, Scout, Maps.me for driving, cycling or jogging; which in turn is likely to lead to feedback (street names, for example or better GPS traces).
There's also a quite active mapping community; who may not realise the impact they can have due to the visual map looking "complete" in a lot of ways.
If you'd like to help, spend a few minutes on either of the above two methods!
