Longitude and latitude are the backbone of geographic mapping. Latitude lines, also known as parallels, run horizontally around the Earth, measuring the distance north or south of the Equator (0? latitude). Longitude lines, or meridians, run vertically from the North Pole to the South Pole, measuring the distance east or west of the Prime Meridian (0? longitude), which runs through Greenwich, England.
Map of the US Longitude and Latitude: Mapping the Continental US
The continental United States lies roughly between 24?N and 49?N latitude, and 67?W and 125?W longitude. This vast expanse encompasses diverse landscapes, climates, and cultures. Understanding these coordinates helps pinpoint locations, calculate distances, and understand regional variations.

Map of the US Longitude and Latitude: Key Locations and Coordinates
Here's a look at some prominent US cities and their approximate coordinates:
- New York City, NY: 40.7128? N, 74.0060? W
- Los Angeles, CA: 34.0522? N, 118.2437? W
- Chicago, IL: 41.8781? N, 87.6298? W
- Miami, FL: 25.7617? N, 80.1918? W
- Seattle, WA: 47.6062? N, 122.3321? W
These coordinates provide a precise location for each city, useful for GPS navigation, mapping applications, and geographic studies.
Map of the US Longitude and Latitude: Impact on Time Zones
Longitude directly influences time zones. The Earth rotates 360 degrees in 24 hours, meaning each 15 degrees of longitude corresponds to a one-hour time difference. The United States spans several time zones, including Eastern, Central, Mountain, and Pacific, primarily determined by longitude.

Map of the US Longitude and Latitude: Using Coordinates in Everyday Life
Beyond academic purposes, longitude and latitude are invaluable in many aspects of modern life:
- Navigation: GPS devices use coordinates to provide accurate directions.
- Weather Forecasting: Weather patterns are often tied to specific geographic locations.
- Search and Rescue: Knowing coordinates is critical in emergency situations.
- Geocaching: A recreational activity that uses GPS coordinates to find hidden treasures.
Map of the US Longitude and Latitude: Fun Facts
- The point farthest north in the US is Point Barrow, Alaska (71.3? N).
- The southernmost point is Ka Lae (South Point), Hawaii (18.9? N).
- The easternmost point is West Quoddy Head, Maine (66.95? W).
- The westernmost point is Cape Wrangell, Alaska (179?46? E - effectively the same as 180?W).
