Not long ago, we began rendering 3D models
on GitHub. Today we're excited to announce the latest addition to the visualization family -
geographic data. Any .geojson file in a GitHub
repository will now be automatically rendered as an interactive, browsable map, annotated
with your geodata.
People are already using GitHub to store everything from Chicago zipcodes to community radio stations to historic hurricane paths, and we can't wait to see what the community will begin to collaborate on next.
Under the hood we use Leaflet.js to render the geoJSON data, and overlay it on a custom version of MapBox's street view baselayer — simplified so that your data can really shine. Best of all, the base map uses OpenStreetMap data, so if you find an area to improve, edit away.
Maps on GitHub support rendering GIS data as points, lines, and polygons. You can even customize the way your data is displayed, such as coloring and sizing individual markers, specifying a more descriptive icon, or providing additional human-readable information to help identify the feature on click.
Looking to get started? Simply commit a .geojson file to a new or existing
repository, or dive into the docs
to learn how to customize the map's styling.
