Representation of geographic coordinates

All geographic coordinates are stored in the WKT format.

In WKT, the pairs of coordinates are always written as x y.

Such tuples, potentially along with other tuples, are then wrapped by one of 18 geometric objects, e.g. POINT, MULTILINESTRING or MULTIPOLYGON.

The most basic example would be POINT(x y).

Accordingly, the order of latitude and longitude in those tuples is always long lat, as in POINT(long lat).

Authoritative data source

The single authoritative source for all data is in Source/json.

If you want to make any changes, please apply them in that folder only.

All other data files are generated from the files in that authoritative set.
