GOM - the Global Overlay Mapping System

Layer Notes - Capital and Other Cities

The positions of all towns and cities on the map overlays were entered by hand, and were calulated using custom software developed specifically for the Global Overlay Mapping System. It is believed to be correct to ±1 pixel, though any errors in the original data would of course be reflected in the final output. The city data, converted from d:m:s to decimal, has been compiled into a number of plain text, comma delineated, continental lists which are available for sale separately.

Choice of cities. Although all capital cities, and most state capital cities were chosen to appear on the maps, the design-brief was to give a good idea of national coverage, whilst trying to avoid clutter and over-crowding of the maps. Therefore, certain large cities have been ommited if very close to more major ones in crowded areas, whilst in less populated regions, smaller cities have been chosen to indicate local population centres.
