Your First Steps With MapRoulette
2021-11-21, 14:45–15:45 (UTC), Room 2
Language: English

In this workshop, we will guide you in your first steps using MapRoulette. The workshop will consist of two parts.
In the first part, we will look at MapRoulette from a mapper’s perspective. We will show how to search for interesting tasks to solve, and how to use the features of MapRoulette to make the tool work for you.
In the second part, we will look at creating your own tasks to share with the mapping community. This does not require programming skills, but you do need a good understanding of the OSM map, tagging, and the Overpass API.


In this workshop, MapRoulette creator Martijn van Exel will guide you in your first steps using MapRoulette.

The workshop will consist of two parts: Mapping with MapRoulette and Creating Tasks with MapRoulette

Mapping with MapRoulette

We will look at MapRoulette from a mapper’s perspective. We will show how to search for interesting tasks to solve, and how to use the features of MapRoulette to make the tool work for you and collaborate with other mappers, for example at events: Virtual Challenges, Leaderboards, Reviewing.

Creating Tasks with MapRoulette

In the second part, we will look at creating your own tasks to share with the mapping community. This does not require programming skills, but you do need a good understanding of the OSM map, tagging, and ideally the Overpass API. Using the MapRoulette Challenge Wizard, we will work through a specific topic for creating a new MapRoulette challenge from scratch.

Martijn is an OSM mapper since 2007. He created various tools for the OSM community, including MapRoulette, a micro-task platform, and Meet Your Mappers, a tool that lets you find out who the active mappers around you are. He has served on the OSMF board between 2014 and 2017, and is currently on the board of OpenStreetMap US. He has worked professionally in GIS for over 15 years.
