GeoJSON files

A GeoJSON file is a format for encoding geographical data structures using JavaScript Object Notation (JSON). It is commonly used for representing geographic features, such as points, lines, and polygons, along with their associated attributes.

When added to a repository, files with a .geojson extension are rendered as a map containing the GeoJSON data when viewed in GitLab.
