The arrangement of
the engineered features of a territory reflects both the nature
of the land and the work of its people. Considered abstractly, this arrangement
is a spatial pattern for human action, a maze of sites of activity and routes of
movement. Its component features are distinguished according to the particular
natural features with which they are associated, the particular kinds of artifacts
present in them, the particular individuals or groups frequenting and using them,
the particular times at which they are occupied and used, and the particular
linkages among them. They are differentiated functionally into several distinct
types of installations.
At no two places are
the arrangements of sites and routes exactly identical, but
their component elements are distinctive to each society and occur repeatedly
in particular associations. The activity of each human group, with its own cultural
and social constitution and a given sort of territory, tends regularly to produce a
characteristic association of features in space.
