MAPS AS MODELS OF THE EARTH

CHAPTER 2 SEC. 1-2

By: Sean & Brandon

Equator

$ Half way between the poles that divides the earth into northern and southern hemisphere

$ It represents 0º latitude

Latitude

$ Is the distance north or south measured in degrees from the equator

$ North pole is 90º north latitude $ South pole is 90º south latitude

Longitude

$ Distance east or west measured in degrees from the prime meridian

$ Imaginary lines that pass through the poles

Prime Meridian

$ Passes through Greenwich, England$ Represents 0º longitude$ Lines are not parallel$ Touch at the poles are farthest apart at

the equator

Mercator Projection

$ A map projection that results when the content of the globe are transferred onto a cylinder

$ Shows the Earth longitude and latitude as straight, parallel lines

$ Lines of longitude are plotted with an equal amount of spaced between them

Conic Projection

A map projection that is made by a transferring the content of the globe onto a cone

Cone touches the globe at each line of longitude but only one line of latitude

Aerial Photographs

Photos from air Photographs are important in helping

map makers to make accurate maps

Remote Sensing

Gathering info. About something without actually being there

It can be as basic as cameras in planes or as sophisticated as satellites with sensor that can sense and record what our eyes cannot see
