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 2020, with the purpose of contributing to OpenStreetMap while having fun. The idea is inspired by the traditional  Advent calendar.

This year, we decided to slightly modify the challenge, so here are the new rules:

  • The Adventures will be divided into 4 weeks according to a different theme;
  • During each week, we will publish some quests related to that theme;
  • Complete the weekly tasks whenever you want, but before the week ends;
  • Save your changesets and post your work on social media using #PoliMappersAdventures;
  • At the end of each week, those who have completed all the quests will receive a special digital badge!

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).


#Week Themes Monday Tuesday Wednesday Thursday Friday Saturday Sunday
OSM Basics
November 30
December 1

As every year, we ask you to start by learning something new about OSM on Learn OSM. Map what you learned, use our hashtag #PoliMappersAdventures on the comment of your changesets, and don’t forget to post your work on social media!

December 2

Map a point feature element on OpenStreetMap: it could be a tree, a bench, a recycle bin.. it's up to you! The important is to have fun and, obviously, make your point on the map and.. on the challenge!

December 3

Add a new line element to the map or update an existing one with additional tags. You could either update the information about an highway or a waterway as well as contribute to some Humanitarian OpenStreetMap Team (HOT) tasks devoted to line features mapping.

December 4

It's time to start mapping some buildings! You could update map features in your areas or look for a project on Humanitarian OpenStreetMap Team (HOT) where buildings are required. Our suggestion? Why not contributing to the "Mapping Tartus" project in Syria that we contributed to in occasion of GIS Day?

December 5

Keep working on the given task!

Do I have to participate in all the activities?

It is not mandatory to participate everyday. ;-)

Can I track changesets made with hastag #polimappersadventures ?


Note: this map can show changesets only for the last 30 days. So maybe, we will need to do screenshot of it before december 31.
