Distortion-Accuracy Trades for UTM
To support this example, linear distortion was chosen as the evaluation parameter
The UTM representation is the TEC SR-7 formulation previously shown
The exact solution is the TEC SR-7 series solution enhanced with two more terms in the series taken from P. D. Thomas
Point (or local) scale is directly related to linear distortion
Point scale is defined in terms of meters per kilometer
Point scale: < 1 means a line is too short > 1 means a line is too long
