Differential measurements

  • differential tensor gravity
  • differential magnetic field
  • differential thermal imaging
  • differential hyperspectral imaging
  • differential precision LIDAR
  • differential Interferometric SAR

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)
