/*
from CF: false_easting(false_northing):
The value added to all abscissa(ordinate) values in the rectangular coordinates for a map projection.
This value frequently is assigned to eliminate negative numbers.
Expressed in the unit of the coordinate variable identified by the standard name projection_x_coordinate (projection_y_coordinate).
