definition: If one observer makes a measurement at a location, but it does not correspond to the measurement another observer would make or has made at that same location, then there is a problem and the observation can be considered to be subject to uncertainty. It is possible that one observation is correct or that neither observation is correct. [Source: Encyclopedia of Geographic Information Science; Uncertainty and Error]
