See new year quests on PoliMappers/Adventures2020!


What are the PoliMappers Adventures?

PoliMappers is going to publish on its social media channels (Facebook user polimappers, Twitter user@PoliMappers) and on our telegram channel PoliMappersAdventures a simple challenge everyday for the entire month of December 2019, with the purpose of contributing to OpenStreetMap while having fun. The idea is inspired by the traditional  Advent calendar.

How to participate?

  1. Follow us on our social media channels.
  2. Read the instructions for the challenge of the day.
  3. Important: add #polimappersadventures in your changeset comment when you modify the OpenStreetMap database. (If you are a member of PoliMappers, please add also the hashtags #youthmappers #polimappers).
