Landslide area detector and program

摘要

PROBLEM TO BE SOLVED: To provide a landslide area detection device and a program in which a user can more easily know an area where a landslide occurs. SOLUTION: A landslide area detection device is at least in each of interference SAR phase difference image data and coherence data obtained by performing interference analysis on old radar measurement data 203 and new radar measurement data 204 capable of interference analysis. A detection means for detecting landslide ground movement based on a combination of landslide characteristics is provided. [Selection diagram] Fig. 4
