1. A non-transitory computer readable storage medium comprising a digital map numerically representing a physical space for a purpose of computational navigation, comprising data structures corresponding to a plurality of cells, each cell corresponding to a particular location within the physical space, said each cell comprising a boundary, the boundary being defined by a first data set of numerical values within a corresponding data structure, the first data set further comprising at least a numerical value for at least a permeability attribute recorded in said corresponding data structure, the permeability attribute numerically representing an ability of the boundary to be traversed; and wherein the permeability attribute pertains to a transmission of radio signals.
