ABSTRACT:
PDA devices, systems, functional data and methods are provided for biasing an active location to an acceptable location within a planned route of a map. A PDA with map biasing capabilities includes a processor communicating with a memory. In biasing a map, an active position and a planned position are received, and an active score and a planned score are associated with each position, respectively. The active position is checked to ensure it falls within a second range, and if it does the active score is made to fall within a first range associated with the planned score, such that the active position is biased to appear as if it were the planned position.
