Geo Location 101

Tips apply globally with a few adjustments depending on the hemisphere. Here's how you can recognize latitude and longitude anywhere:

Latitude and Longitude

1. Latitude (Vĩ độ) — Measures North-South

  • Ranges: -90° to 90°
  • Northern Hemisphere (N): Positive (0° to 90°) → e.g., Vietnam, USA, Europe
  • Southern Hemisphere (S): Negative (0° to -90°) → e.g., Australia, Argentina
  • General rule: The number usually falls between -90 to 90, and in most cases, it's the smaller absolute value in your coordinates.

2. Longitude (Kinh độ) — Measures East-West

  • Ranges: -180° to 180°
  • Eastern Hemisphere (E): Positive (0° to 180°) → e.g., Vietnam, China, India
  • Western Hemisphere (W): Negative (0° to -180°) → e.g., USA, Canada, Brazil
  • General rule: If you're in Asia, Africa, or Australia, your longitude is positive. If you're in the Americas, it's negative.

Applying the Rules Globally

Region Latitude (N/S) Longitude (E/W)
Vietnam 8°N to 23°N 100°E to 110°E
USA 24°N to 49°N -67°W to -125°W
Europe 35°N to 71°N -10°W to 60°E
Australia -10°S to -43°S 113°E to 153°E
South America -55°S to 12°N -35°W to -81°W

Quick Recognition Guide

  • Latitude is smaller (absolute value ≤90), indicates North/South
  • Longitude is larger (absolute value ≤180), indicates East/West
  • If you see negative numbers, use the hemisphere rules above

So, the same tips work anywhere—you just need to check whether the numbers are positive or negative! 🌍🚀
