HISTORICAL MAP OF TERRITORIES REPRESENTED ONLY BY MODELED OBJECTS

摘要

PROBLEM TO BE SOLVED: To provide a historical map of territories represented only by modeled objects to realize a method by which the complexity of alternately checking a territory and time is eliminated and the simplicity and clarity of looking at territories only by way of modeled objects without displaying a map and grasping a historical map by way of concrete objects are achieved.;SOLUTION: The history of each territory is represented only by a modeled object. The modeled objects are represented on a total of three axes including a vertical axis, a horizontal axis and a time axis, and both ends of each modeled object on the time axis constitute a line or a face of the shape of a territory; each territory is a modeled object arranged in a position to which the total of three axes including the vertical axis, the horizontal axis and the time axis of the territory apply and shaped by linking boundaries between lines or faces of territories adjoining on the time axis; one of the two ends of each modeled object on the vertical axis is the minimum value of the territory on the vertical axis and the other is the maximum value on the same in a period, one of the two ends of each modeled object territory on the horizontal axis is the minimum value of the territory on the horizontal axis and the other is the maximum value on the same in the period, and one of the two ends of each modeled object on the time axis is the territory at the first time in the period and the other is at the final time in the same, resulting in expression of the history of the territory.;COPYRIGHT: (C)2014,JPO&INPIT
