Datums Measures the Ground Beneath Malaysia and Singapore
A satellite-monitoring service that tracks building-level ground settlement and differential movement to the millimetre.
Field notes
The service uses radar satellite archives to reconstruct surface movement beneath individual buildings, with records stated to extend back to 2015. Its vocabulary separates settlement from differential movement—the latter being associated on the page with cracks caused when one part of a building sinks faster than another. Klang Valley coverage is described as in development, and the page explicitly limits the service to surface monitoring rather than structural assessment, ground investigation, or reliable sinkhole prediction.
