Whose system of latitude and longitude helped in mapmaking?
Jason
Why do you reckon 180 degrees of longitude and only 90 of latitude?
There are 180 of latitude too - 90 south and 90 North.
What is the starting line for the lines of longitude?
No. The Prime Meridian is about Longitude, which was far more difficult to calculate than Latitude. Latitude can be measured by knowing how high the Sun is above the horizon & by the Stars at night. Longitude needs the addition of knowing time at one place & another place & speed & direction of movement. The Prime Meridian, 0 degrees Longitude runs from Pole to Pole through Greenwich, London. (The Headquarters of the Royal Navy at the time) 0 degrees latitude is the Equator.
