#CompletetheMap Milano

CompletetheMap arrives in Italia. Join us in mapping Milano.

Over the last few months, students at the Politecnico di Milano have become increasingly active in OpenStreetMap and Mapillary. We’re partnered with the great professors and researchers of the university with the aim of photo mapping East Milano during October. The idea of #CompletetheMap is to divide a city into zones and then fill them in by capturing street-level imagery throughout the city. As you move through the city, your imagery of roads, bike lanes, and footpaths help to complete each zone and eventually #CompletetheMap.

The area we have selected is in close proximity to Politecnico di Milano and thus serves as a good starting point to increase imagery coverage in the city. Anyone living in Milano or passing through during this time is welcome to join the #CompletetheMap challenge. Read on for more info on how the challenge works and how you can contribute.

Follow the action here.

The Challenge

Milano has been divided into a 5 x 5 grid. To participate in the challenge, simply capture imagery of streets, bike paths, and sidewalks between October 1st at 00:00 Milano time and October 22nd at 23:59. The contributor with the most images throughout the grid at the conclusion of the challenge wins #CompleteTheMap Milano.

If you’d like to take part, follow us on Twitter or Facebook and start capturing images in your area. Good luck!

The Rules

How do I enter the challenge?

Anyone capturing within the grid will automatically participate in the challenge. You don’t need to sign up for your images to be counted.

The Grid

We will be checking coverage every few days and assigning a color to each zone that represents the percentage coverage of roads and paths within that zone. Red will represent 20% or less of coverage, yellow between 20% and 80%, and green greater than 80%. Only images captured from day one of the competition (October 1st) will be counted.

Rankings & Updates

We’ll be maintaining a live page with the results that you can visit any time here. As usual, you’ll also be able to get updates on Twitter and Facebook.

How to win

The winner of each zone will be the contributor with the most images in that area when the zone is marked as complete (goes green). The overall winner will thus be the one to collect the most zones by improving coverage in that area. The competition will end when all the zones go green or on October 1st, whichever comes sooner.

To keep the challenge as fair as possible, we will make sure that images taken in each zone are useful. When necessary, we’ll manually update the zone to make sure it accurately reflects the state of image coverage in that area. You’re welcome to send in feedback to tell us which zones need to be adjusted.

Invite Friends

If you would like to invite your friends to take part in the challenge, all they have to do is capture within the grid area and they will automatically appear on the leaderboard. If they want to stay updated, make sure they subscribe to our email updates and follow the #CompletetheMap hashtag on Facebook and Twitter.

And we’re off!

Charge your phones, get your action cameras out, and #CompleteTheMap Milano! Have fun exploring the city.

P.S. Nominate your city here if you’d like to see the challenge in your neighbourhood. We’ve also open sourced the code for the grid and leaderboard so that you can run the challenge yourself at any time.
