VISUALIZATION DEVICE FOR GROUND SURFACE DISPLACEMENT IN INTEREST AREA AND VISUALIZATION PROGRAM OF GROUND SURFACE DISPLACEMENT IN INTEREST AREA

摘要

PROBLEM TO BE SOLVED: To provide a visualization device of a ground surface displacement in an interest area for clearly expressing a displacement of a ground surface acquired by interference SAR and a visualization program of a ground surface displacement in the interest area.SOLUTION: A displacement generation part 12 generates displacement information from time series image data of a ground surface which is an observation object, acquired by a radar image data acquisition part 10 from a radar device, and a displacement information collection part 18 collects the displacement information for every division area obtained by dividing by the interest area division part 16, the interest area extracted from the ground surface which is the observation object by the interest area extraction part 14. A representative value calculation part 20 calculates a representative value of a displacement in each division area based on the displacement information collected for every division area, and a display control part 24 displays the representative value.SELECTED DRAWING: Figure 2
