摘要

PROBLEM TO BE SOLVED: To provide a change discrimination device capable of accurately determining the change of a building between the previous fiscal year and the present fiscal year.SOLUTION: The discrimination device includes: a memory 380 for storing DSM image data in the previous fiscal year; a memory 370 for storing precision orthophoto image data in the previous fiscal year; a memory 280 for storing DSM image data in the present fiscal year; and a memory 270 for storing precision orthophoto image data in the present fiscal year. A computer performs: a step (500) of generating DSM/precision orthophoto composite image data in the previous fiscal year from the precision orthophoto image data in the previous fiscal year and the DSM image data in the previous fiscal year; a step (400) of generating DSM/precision orthophoto composite image data in the present fiscal year from the precision orthophoto image data in the present fiscal year and the DSM image data in the present fiscal year; and steps (900 and 1000) of displaying the DSM/precision orthophoto composite image data in the previous fiscal year and the DSM/precision orthophoto composite image data in the present fiscal year in a region allowing comparison between them on the screen.SELECTED DRAWING: Figure 1
