Atlastory Base Map
Atlastory is the visualization of history on a map. The goal is to create a free interactive web map that spans all of history, with the ability to see what the world looked like 20, 50, or 1,000 years+ in the past. For further discussion and collaboration outside of GitHub, visit forum.atlastory.com.
This is the Atlastory Base Map, a political and cultural map that spans human history. To contribute, Fork the repo and issue a pull request.

├── africa ├── asia │ ├── admin-1 │ │ ├── 1871-1900.geojson │ │ └── 1900-1910.geojson │ └── admin-2 │ └── 1900-1920.geojson ├── central-america └── central-asia
- Regions — the region of the world
- Types — each folder is a map type level
- Time periods — each type folder has GeoJSONs representing the time period for that data
General split lines:
north-america: North America (+Greenland)
central-america: Central America (+Caribbean)
south-america: South America
middle-east: Middle East
central-asia: Central Asia (+Russia)
asia: Asia (+Southeast Asia)
oceania: Australia, NZ, Pacific
Each region will later be combined to form a global map. So the split doesn't need to be exactly down these lines -- as long as 2 GeoJSON files in the same period don't replicate a shape. So Ukraine can be included in
central-asia in one period and
europe in another.
(2) Shape types (
level-name object type — Shape type(s))
admin-1polygon — sovereignty, country, dependency, colony
admin-2polygon — state, province, republic, ...
admin-3polygon — county, ...
settlementpoint — city, capital-[1-3], town, village
(3) Time periods (GeoJSON)
- Must be in GeoJSON format (projection is always WGS 84 (4326))
- Periods can be any length in 1-year intervals.
- Years begin and end on January 1. So the file
1940-1945goes from January 1, 1940 to January 1, 1945. The file
1945-1946spans the one-year period January 1, 1945 to January 1, 1946.
- Periods can be changed to whatever necessary as the map data changes over time.
- Periods should never overlap within the same type.
