• In 1569, a geographer named Gerardus Mercator created a flat map to help sailors navigate long journeys across the globe.• The Mercator projection, or

method of putting a map of the Earth onto a flat piece of paper, is used by nearly all deep-sea navigators.• The Mercator projection is a

conformal map, meaning that it shows correct shapes, but not true distances or sizes. • There are many types of

other projections of the globe.

Types of MapsTypes of Maps

There are three basic types of maps:

PHYSICAL POLITICAL

and THEMATIC.

Physical MapsPhysical Maps• Physical maps show

the natural features of the Earth.

• Physical maps do not contain man made features.

• For example, a

physical map would be a map of what you would see if you were looking down on Earth from space.

Physical MapsPhysical Maps

When you When you look at this look at this map, what do map, what do you see?you see?

Notice you do not see country borders or city markings. These divisions are created by people. For example, there is no actual line dividing Texas from its bordering states.

Although some astronauts (with the use of binoculars believe it or not) are able to see roads, large ocean tankers, and even the Great Pyramids from space, at very high altitudes, none of these are visible and all you are left with are natural land formations.

Political MapsPolitical Maps

Political MapsPolitical MapsUnlike physical maps, political maps show how humans have impacted the landscape. For example, city names, roads, country borders, etc. are all part of political maps.

Political maps change frequently (physical maps change very, very slowly through geologic processes) and must be redrawn often. A political map of the world that is 50 years old is no longer accurate.

Wars and ethnic conflict are two major causes political maps change.

Thematic MapsThematic MapsThematic maps can represent a variety of information including things like climate, precipitation, vegetation, elevation, population, life expectancy, etc.

Thematic maps are generally used when you are looking at a single piece of information.
