Data classification method that optimizes the groups of data values, to minimize the difference between the values of the same class.

To classify the data according to natural groupings inherent inside.

Type of Systematic Error caused by natural phenomena (i.e. wind, temperatutre, humidity, atmospheric pressure, atmospheric refraction, gravity, magnetic declination, etc…), which can be mathematically modelled and eliminiated.

Properties of the target when measured, affects the magnitude of received signal. Type: 1) Point Scatterer (e.g. void) 2) Line Reflector (e.g. pipeline) 3) Planar Reflector (e.g. smooth surface)

Chart of water depth, shoreline of land and prominent topographical features to help with navigation.
