Longitude and Latitude


Ohhh I should have mention this before. Because this is very important…… without knowing this....

Latitude (parallels) - Horizontal line

This is the angular distance, in degrees, minutes, and seconds of a point north or south of the Equator.

 

 

 

 

Longitude (meridians) - Vertical line

This is the angular distance, in degrees, minutes, and seconds, of a point east or west of the Prime (Greenwich) Meridian.





Distance between Lines

By dividing the circumference of the earth (apprx. 25,000 miles) by 360 degrees, the distance on the earth's surface for each one degree of latitude or longitude is just over 69 miles (111 km).
