Question

What is the primary purpose of using Eastings and Northings on a topographic map instead of just latitude and longitude?

• A. To divide the map into different climate zones.
• B. To measure the elevation of mountains and hills.
• C. To determine the exact location of small geographical features on large-scale maps.
• D. To align the map with the magnetic North Pole.

Answer 1

Answer:

C. To determine the exact location of small geographical features on large-scale maps.

• Grid lines (Eastings and Northings) provide a localized, high-resolution coordinate system that translates the Earth's curved surface into a flat, manageable square grid. • While latitude and longitude are calculated in degrees, minutes, and seconds—which vary in distance depending on where you are on the globe—grid references use fixed metric units (meters and kilometers) that remain constant across the specific map you are using.
