PREDICTION RANGE DISPLAY METHOD FOR DIGITAL MAP

摘要

PROBLEM TO BE SOLVED: To accurately plot the contour of the range predicted by route simulation from a node on an outer peripheral closed curve by searching simulation history. SOLUTION: An arrival possible range calculation processing 203 calculating an arrival possible range from digital map data 201 and one point in the data within prescribed time is executed. A display data generation processing 204 for generating display data in the arrival possible range is executed from a simulation history table 202 storing the process of the processing, At the time of executing a display processing 205 for displaying the display data, a display data generation processing generates display data by considering a tourist resort retrieval processing 209 executed by using tourist resort data 208.
