I noticed you recently started mapping in the Salt Lake City area. Welcome! I am a fellow mapper living in SLC. I have been contributing to OSM since 2007. If you have any questions please just drop me a line.

We have a small local group of OSM mappers that get together from time to time in / near downtown SLC, usually on the second Wednesday of the month. You’re welcome to join us! We announce our events on OSMCal.

If you’re a Slack user (or don’t mind becoming one), there is an active and friendly community of OSM mappers there, and we have a #local-utah channel on it. You can join via this link.

Happy mapping!

MapRoulette News for August 2020

MapRoulette News for August 2020

We've been keeping busy this summer! Here are the highlights for the July releases.

Easier Challenge Creation

We completely redesigned the Challenge Creation Wizard, with a focus on gathering the essentials first, and de-emphasizing less-used settings and options. If you have used the Challenge Creation wizard before, we hope you will appreciate the improvements! And if you have never tried to create a MapRoulette Challenge before, give it a try and see how easy it is to create Tasks for fellow mappers to solve!
