Displacement output device, displacement output method, and recording medium

A displacement output method comprising:

• acquiring a first ground surface displacement at a first point from a synthetic aperture radar;
• estimating a second ground surface displacement at a second point different from the first point using the acquired first ground surface displacement;
• clipping at least one of the first ground surface displacement and the second ground surface displacement included in a preset first region from the first ground surface displacement and the second ground surface displacement, the preset first region being a region extracted by excluding at least one of a region where a building requiring privacy protection is constructed and a region where provision of information is legally restricted;
• and
• outputting at least one of the first ground surface displacement and the second ground surface displacement included in the first region.

A non-transitory computer-readable recording medium that records a program for causing a computer to perform a method, the method comprising:

• acquiring a first ground surface displacement at a first point from a synthetic aperture radar;
• estimating a second ground surface displacement at a second point different from the first point using the acquired first ground surface displacement;
• clipping at least one of the first ground surface displacement and the second ground surface displacement included in a preset first region from the first ground surface displacement and the second ground surface displacement, the preset first region being a region extracted by excluding at least one of a region where a building requiring privacy protection is constructed and a region where provision of information is legally restricted;
• and
• outputting at least one of the first ground surface displacement and the second ground surface displacement included in the first region.
