Ok, I'll be more explicit :)

If I want to generate random coordinates across North America by uniformly
sampling latitudes and longitudes, the geographical distance between these
coordinates would decrease towards higher latitudes. I'd like to be able to
generate coordinates (e.g. a grid) such that the geographical distances
between coordinates would be constant regardless of latitude.
