Mapping
Essential Question:How do you find the absolute location of a place?
A. 5 Parts of a Map
1. scale 2. title
3. compass4. legend/key5. grid
1. scale - ratio of a distance on the map to the corresponding distance on the ground
2. Title - tells what the map is about
3. Compass - direction arrow that points north on the
map- points the four directions as well
4. Legend - explain the various colors and symbols used on the map
5. Grid
Where these two lines (latitude and longitude) cross is the absolute location on the map.
- lines used to show the location of places
B. Latitude and Longitude- are imaginary lines on a map- help you to pinpoint an exact location
on a map
1. Latitude
- 0 degrees latitude is called the EQUATOR.
- tells you how far NORTH or SOUTH of the equator you are
Countries that the Equator passes through:
• Ecuador• Columbia• Brazil• Sao Tome and Principe• Gabon• Congo• Democratic Republic of the Congo (Zaire)• Uganda• Kenya• Somalia• Maldives• Indonesia• Kiribati
2. Longitude
- 0 degrees longitude is called the PRIME MERIDIAN.
- tells you how far EAST or WEST of the prime meridian you are.
Prime Meridian- based at the Royal Naval Observatory, Greenwich, England
Countries that the Prime Meridian Passes through
• United Kingdom• Mali• France• Burkina• Spain• Ghana• Algeria• Togo
Latitude Longitude
When given a location, LATITUDE is always listed FIRST and LONGITUDE is listed SECOND.
Ex. 34.0500° N, 118.2500° W = Los Angeles
33.9431° N, 117.2283° W = Moreno Valley
33.7967° N, 117.2244° W = Perris
Let’s do some
plotting.

State the coordinates for each of the letters in the figure above:
C. Hemisphere - half of a sphere
Northern Hemisphere Western Hemisphere
Southern Hemisphere Eastern Hemisphere
D. Earths Diameter- NOT a perfect sphere
- Wider at the equator than at the poles
