Working draft
ISO/AWI 18674-9
A working group has prepared a draft.


This Standard specifies the measurement of displacements by means of geodetic instruments carried out for geotechnical monitoring. It refers to position measurements where a signal travels through air/the atmosphere between an instrument and a measuring point (target). General rules of performance monitoring of the ground, of structures interacting with the ground, of geotechnical fills and of geotechnical works are presented in ISO 18674 1:2015. This document is applicable to measurements by means of:  Tachymeter (manual or robotic)  level In informative annexes, this document also refers to principles of some techniques that can be applied to the monitoring of displacements of topographic surfaces:  satellite radar interferometry (INSAR);  terrestrial radar interferometry;  laser scanning;  GNSS. NOTE : This document fulfils the requirements for the performance monitoring of the ground, of structures interacting with the ground and of geotechnical works by the means of geodetic instruments as part of the geotechnical investigation and testing
