and Africa emphasise that land patterns are not confined to such terrain. 
A typical temperate maritime scarpland pattern of which the three facets

An Index of Patterns 
Patterns of this nature, that is assemblages of inter-related facets could thus 
be the basis for indexing annotated air photographs. The photographs would 
be accompanied by a description and diagram showing how the pattern is 
composed of its constituent facets. But although each pattern covers an appre 
ciable area and any country can be subdivided into a limited number of them 
there are probably still a large number in the world as a whole. If one wishes
