摘要：
A look-up table is defined by at least one reference point, and rows and columns that are offset from the reference. The table rows and columns correspond to ordinate and abscissa data points representing geographic locations. Each data point offset in the table corresponds to a predefined geographic offset. The look-up table contains machine-stored values at each table location, with each value representing a particular one of several guidance zones. The real-time determination of the guidance zone is made by first determining present location using GPS or other wireless location signals. The corresponding table location is identified by calculating latitudinal and longitudinal offsets from a reference point, and using these offsets as the two indices to access a double-indexed array. The value retrieved from the indexed array identifies the guidance zone. Each guidance zone has an associated set of characteristics used to provide behavioral guidance to an animal.
