Understanding Geographic Coordinates
What are Latitude and Longitude?
Geographic coordinates are a system used to specify any location on Earth using two values: latitude and longitude. These imaginary lines create a grid system that allows precise location identification.
Latitude
- •Measures north-south position
- •Ranges from 0° (Equator) to ±90° (Poles)
- •Positive values for North, negative for South
Longitude
- •Measures east-west position
- •Ranges from 0° (Prime Meridian) to ±180°
- •Positive values for East, negative for West
Conversion Formulas
DMS to DD
DD = Degrees + Minutes/60 + Seconds/3600
DDM to DD
DD = Degrees + Decimal_Minutes/60
Example Conversion
Convert 40° 44' 54.3" N to decimal degrees:
DD = 40 + 44/60 + 54.3/3600 = 40.748417°
