YouthMappers Activity Tracker

This dashboard quantifies the OpenStreetMap editing activity by mappers associated with YouthMappers chapters around the globe. There are over 400 chapters in more than 75 countries around the world. This dashboard shows edits from thousands of mappers in these chapters.

Don't see your edits or your chapter?

We can only track edits by mappers that are registered or listed in an official YouthMappers chapter on OSM Teams. Please see the instructions to join your chapter on OSM Teams!

Using The Map

Filtering by Time

The timeline along the bottom shows the relative number of chapters active each day in OSM. By clicking and dragging across the timeline, the map will filter to only show changesets submitted in that time range.

Changeset Information

Click Show Bounding Boxes to show the bounding box of changesets performed that day. The bounding boxes appear unstraight because they can also be viewed in 3d!

Tilt the map with Control + Click & Drag to see the actual terrain. The numbers inside the bounding boxes represent the number of features edited in that box on any given day. Hovering over this number will give more information.

Filtering by Chapter

Choosing a chapter from the Dropdown menu labeled Choose A Chapter will show only edits from mappers associated with that chapter. Multiple chapters can be chosen consecutively. Chapters can be unselected by clicking the[X] button next to their name.

How are these numbers calculated?

Did you know that the entire editing history of OpenStreetMap is available in a queryable database part of Amazon's Open Data Program? We search the full history to count all of the edits to highways, buildings, amenities, or other objects by OSM users known to be in, or have been part of a YouthMappers chapter.

The numbers presented here are just a subset of all edits from YouthMappers chapters because there many mappers associated with YouthMappers chapters that are not yet registered on OSM Teams. If you are part of a YouthMappers chapter and not registered on OSM Teams, please see the instructions to join your chapter on OSM Teams!


How can I download the data for use in my own analysis?

All of the data that powers the map on this website is available as GeoParquet here: s3://youthmappers-usw2/activity/daily_rollup.parquet

You can download the it here: https://youthmappers-usw2.s3.us-west-2.amazonaws.com/activity/daily_rollup.parquet and read it with an analysis tool like GeoPandas.

You can also access the data directly on S3 with DuckDB:

  SELECT 
    sum(buildings.new), sum(buildings.edited)
  FROM 
    read_parquet('s3://youthmappers-usw2/activity/daily_rollup.parquet');

You should see something similar to this: 

  ┌──────────────────────┬───────────────────────┐
  │ sum(buildings."new") │ sum(buildings.edited) │
  │        int128        │        int128         │
  ├──────────────────────┼───────────────────────┤
  │           25,174,061 │             2,051,233 │
  └──────────────────────┴───────────────────────┘

OSM Teams

OSM Teams is a platform that allows OpenStreetMap users to organize themselves into teams. This allows more convenient tracking of membership among groups of mappers, which enables easier collection of mapping metrics and statistics.

YouthMappers on OSM Teams

The YouthMappers Organization on OSM Teams consists of more than 2,200 mappers across more than 300 teams. Each team represents an active YouthMappers chapter. Edits from mappers that are members of these teams are counted on the Activity Tracker.
