Data for dev3map
cities.json: location and size of citiesclaims.json: boundary, name, shown color of nationstransit.json: railway stations and connections ("edges")
Claim positions coordinates are in z,x order, because Leaflet uses the lat,long standard.
After adding/editing a claim, run
ajv -s schemas/claims_schema.json -d claims.json --all-errors
to check if it's valid. You can install ajv through npm using
npm install -g ajv-cli
