Definition And Purpose

Deformation Monitoring is a Land Survey activity during which repeated observations are made within a specified time frame for the purpose of detecting and quantifying movements of natural and man-made structures. Such monitoring could be of a routine nature (e.g. a dam at high and low water marks) or made necessary by an abnormal condition (e.g. major works near a tall building)g).

Methodology and Instrumentation

Detecting and quantifying movements require the use of very precise equipment. Such movements are very small and to accurately measure them requires meticulous fieldwork as well as rigorous analysis of observed data.

Methods applicable range from close-range photogrammetry with the use of terrestrial Camera and precision plotters to observation by precise theodolite and levels.
