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 │ └──────────────────────┴───────────────────────┘
