Study Notes
Latitude and Longitude
Latitude vs Longitude
-
Latitude:
- Measures distance north or south of the Equator
- Ranges from 0° at the Equator to 90° at the North Pole and -90° at the South Pole
- Also known as parallels
-
Longitude:
- Measures distance east or west of the Prime Meridian
- Ranges from 0° at the Prime Meridian to 180° East and -180° West
- Also known as meridians
Geographic Coordinates
- A system of locating points on the Earth's surface using latitude and longitude
-
Format:
- Latitude (degrees, minutes, seconds) + Longitude (degrees, minutes, seconds)
- Example: 37° 45' 22" N, 122° 26' 55" W
-
Types of Coordinates:
- Degrees, Minutes, Seconds (DMS): most precise format
- Degrees, Decimal Minutes (DDM): less precise than DMS, but more readable
- Decimal Degrees (DD): least precise, but most commonly used in GPS systems
