We are about to launch the new version of MapRoulette! Finally! The most obvious changes are that you now sign in using your OSM account - so you can track your and other mappers' progress, and multiple challenges being available to choose from! We will launch the day after tomorrow with four new challenges to start with: the familiar Zorro Ways, ways with overlapping parts, wrong one way ways (if you know a better name, let me know..) and tangled ways. More to come!
Behind the scenes much more has changed. There is now an API for challenge providers to post their own challenges (let me know if you want access), challenges can have an area associated with them so you will be able to choose a challenge that is local to you, and they also have difficulty levels. The entire application has also been rebuilt from the ground up to be more stable, scalable, and allow more flexibility for different types of challenges in the future. If you want to see how MapRoulette is built, check out MapRoulette on Github.
So, on March 12, head on over to maproulette.org and start fixing!
