Why is it important to be specific when it comes to determining latitude and longitude

Because if you take a guess it could mess where the whole place is

The lines of longitude run north and south. They are used to define the East-West position of a location on the planet. They run perpendicular to the Equator and latitude lines. ... However, the Prime Meridian or Greenwich Meridian is used as the primary reference point because it is set to 0 degrees longitude.

Nah i’m goody that’s a good question tho
