There have been two series running on BBC 4 in the UK over recent months and currently with a cartographic and historical focus:
see - The Beauty of Maps
This Vermeer - The Art of Painting - was featured in one programme and reveals the power and status of maps as Wikipedia also explains.
It is natural to see the health career model as a map, but this map is not just the preserve of the wealthy. Hodges' model can be used universally by all - a common framework.
Use of the term map and its synonyms is in turn common in medicine in many forms:
WHO Global Health Atlas
The Malaria Atlas Project (MAP)
The above sites reveal how maps, charts and atlases relate the individual, geography and health.
In addition to its geographic connotation projection also has a psychological meaning. Hodges' model provides a substrate* on which to project personalised, national and global health.
An individual; a people; a nation: for each a journey .... and for each a map ....
