Track Compatibility
Craw (1988a, 1989a) formalized a quantitative method based on character
compatibility(Lequesne1982).Individualtracksarecodedinanarea×track
matrix that is analyzed for track compatibility, where two individual tracks are
compatible or congruent with each other if one is a subset of the other or
they are the same in a pairwise comparison. The largest set of compatible
tracks is called a clique, and it is used to construct the generalized track.
The individual tracks ( figs. 4.9a - 4.9d ) are coded and input into an area
× track matrix, where the presence of a track in an area is indicated with
“1” and its absence with “0” ( fig. 4.9e ). The matrix is analyzed in search of
compatibility between the tracks. The set of compatible tracks represents a
clique that is used to construct the generalized track connecting the areas,
which is drawn on a map ( fig. 4.9f ) . In order to allow the statistical evalu-
ation of the generalized tracks, matrices of the same size as the real matrix
are generated randomly. If the number of randomly generated matrices that
display cliques equal to or greater than that obtained from the real data is
large, the statistical meaning of the generalized track will be small.
