Claim Text:
1. A computer-implemented method comprising: (a) reading or receiving from a first computer-readable storage medium electronic indicia of a first dataset, said first dataset comprising, for each one of a multitude of at least partly contiguous spatial areas, a corresponding set of spatial coordinates of a closed, polygonal boundary of that spatial area; (b) using one or more computer processors programmed therefor and operatively coupled to the storage medium, generating electronic indicia of a second dataset, said second dataset comprising, for each one of a multitude of piecewise-linear spatial boundary segments, a corresponding set of spatial coordinates of that spatial boundary segment; and (c) storing the electronic indicia of the second dataset on a second computer-readable storage medium operatively coupled to the processor, wherein: (d) the polygonal boundary of each spatial area comprises one or more corresponding boundary segments; (e) each boundary segment forms a portion of the closed, polygonal boundary of at most two adjacent spatial areas and separates those spatial areas; and (f) space on the second storage medium occupied by the electronic indicia of the second dataset is less than space on the first storage medium occupied by the electronic indicia of the first dataset.
