In “The Cities and the Sea”, replace the first bullet point with:

* A location, which is privately tracked by the Capital and defaults to blank
* Some coordinates, which are either “unknown” or a pair of integer Latitude and Longitude degree numbers (Longitude being a value from -25° to 25°, Latitude from 25° to 50°). These are publicly tracked through the Container Draft Map: where a City does not appear, its coordinates are unknown.

Replace “where on the map they wish their Location to be (upon doing so, their Location is set to the specified location)” with

their desired Latitude and Longitude (upon doing so, their coordinates are set to those values)

Replace “reflects the location of each City” with “reflects the coordinates of each City”.

Add a paragraph:-

If a City has a Location but unknown Coordinates, the Capital should set that City’s Coordinates to values that they consider to represent its Location, and then its Location to be blank. If all Cities have blank Locations, the Capital may repeal this paragraph and remove the bullet point in this rule that defines Locations.
