When this map is printed on an electronic plotter directly from digital files, dimensional 

calibration may vary between electronic plotters and between X and Y directions on the

When this map is printed on an electronic plotter directly from digital files, dimensional 

calibration may vary between electronic plotters and between X and Y directions on the 

same plotter, and paper may change size due to atmospheric conditions; therefore, scale 

and proportions may not be true on plots of this map.
