information can be derived from measurements performed at regular time intervals
(for example, each day) at the same time of day, to aid in the detection of
changes, such as:
-
(onset of) oil leakage from a pipeline (through differential thermal imaging,
or, differential gas analysis)
-
detection and monitoring of surface subsidence, for example, as a result of
extracting oil and gas (through differential LIDAR, or, differential
Interferometric Synthetic Aperture RADAR)
-
depletion of an oil well over time (through differential tensor gravity)
