The Earth and the Graticule
The graticule is the network of latitude and longitude lines on maps and globes, helping us pinpoint exact locations on Earth.
Core concept
Latitude lines run horizontally around Earth, measuring distance north or south of the equator, from 0° to 90°.
How it works
Longitude lines run vertically from pole to pole, measuring distance east or west of the Prime Meridian, from 0° to 180°.
Why it matters
Together, latitude and longitude lines form a grid called the graticule, allowing us to identify any location using coordinates.
Key detail
The graticule is essential for navigation, mapping, and precisely describing locations anywhere on Earth's surface.

Quick notes
• Graticule: network of latitude, longitude lines.
• Latitude: horizontal, measures N/S of equator.
• Range: 0° to 90°.
• Longitude: vertical, pole to pole.
• Measures E/W of Prime Meridian, 0° to 180°.
• Together they form a grid (graticule).
• This identifies locations via coordinates.
• It's essential for navigation, mapping.
