Abstract
An apparatus and method for monitoring environmental conditions that processes information to create and display information concerning changes in the status of environmental conditions. The apparatus comprises a means of transforming measured values of more than one parameter of the condition using a function dependent on at least one of the baseline and critical values of the conditions. In a preferred form, the function is a non-linear transformation function. The apparatus further includes mapping values for mapping the function to a sequence of reference values and generating a deviation indicator for each parameter. The deviation indicators are then analyzed to generate and display information concerning the changed status of the environmental (i.e., meteorological or geological) conditions.
