A measuring method and system involving a measuring coordinate probe, which can be moved precisely, by appropriate actuators, with respect to a positioning platform (60) on which the probe is mounted; and whose position relative capable to said positioning platform (60) can be measured, by suitable encoders (780). The invention can be carried out with probes, actuators and encoders of different nature. The actuators (730) preferably allow the motion of the probe according to two or more independent degrees of freedom, so that the probe itself can be moved in a plane, or in a three-dimensional region of space, and its orientation can be chosen, within some suitable limits. The method and system of the invention provide very exact local measurement, even if the platform (60) does not deliver the very best precision.
