# FreeGeoDB Free database of geographic place names and corresponding geospatial data ## Entities * airports * cities * countries (admin-0) * lakes * ports * railroads * regions (admin-1) * roads * time zones ## Formats * [CSV](Distribution/CSV/) * [JSON](Distribution/JSON/) * [MySQL](Distribution/MySQL/) ## Representation of geographic coordinates All geographic coordinates are stored in the [WKT format](https://en.wikipedia.org/wiki/Well-known_text). 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`](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. ## Contributing All contributions are welcome!
