First of all, we have to patch this data, so that it becomes more useful
|
|
|
|
|
both for the list and the map. Ox.getCountryByCode gives us the names of
|
|
|
|
|
the country, region and continent. For the map, we need a geoname, and
|
|
|
|
|
the cities have to be rectangular areas, not just points. So we set the
|
|
|
|
|
area to 100 square meters per inhabitant, which will turn out to be
|
|
|
|
|
relatively realistic. Then we calculate how large the resulting square
|
|
|
|
|
will be, in degrees. (The number of degrees from west to east depends on
|
|
|
|
|
the city's proximity to the equator. OxJS has some utility functions
|
|
|
|
|
built in that make this easy to compute.) Finally, we can set the values
|
|
|
|
|
for south, north, west and east. A nice side effect of deriving the size
|
|
|
|
|
of the city from its population is that the map, which will always show
|
|
|
|
|
the largest places in the visible area, will now show the most populated
|

cities.
