It&#x27;s so difficult to keep latitude&#x2F;longitude straight; which is both the reason for the correction and why I looked it up to be sure.  Longitude is the measurement of east-west relative to another point of reference (the prime meridian).  Latitude is the measure of angular distance from the equator.<p>Even though the Earth isn&#x27;t a perfect sphere, at this scale it&#x27;s effective enough to consider it one.  Latitude lines will be parallel with each other.  Longitude lines converge, more closely on the greater latitude parallel.
