2What is a map?
- A map is a representation, usually on a flat
surface, of the features of an area of the earth
or a portion of the heavens, showing them in
their respective forms, sizes, and relationships
according to some convention of representation. -
-
Now what does that mean?
3- A map is a representation,
- A map is a drawing or model
- usually on a flat surface,
- of a round Earth on a flat surface,
- of the features of an area of the earth
- that shows the landforms (mountains, rivers,
etc.) - or a portion of the heavens,
- or part of the sky in a particular region,
- showing them in their respective forms, sizes,
and relationships - drawn to scale
- according to some convention of representation.
- using an accepted form of drawing or model.

10Types of Maps
- There are three basic types of maps
- PHYSICAL
- POLITICAL
- and
- THEMATIC.
-
11Physical 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.
12When you look at this map, what do 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.
13Political Maps
Unlike 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.

15Thematic Maps
- Thematic 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.
16Cultural Maps
- In geography, a physical feature is something
which has been made by nature. Physical features
are commonly divided according to which of the
four 'spheres' they are found in. Features such
as air pressure (weight of the air) and
temperature are part of the atmosphere (air
surrounding the Earth). Oceans and rivers are
part of the hydrosphere (all water in and around
the Earth). Landforms including mountains and
valleys are considered part of the lithosphere
(solid levels of the Earth's outer layers), while
vegetation and wild animals are found in the
biosphere (living organisms and their
environment). - It is important to remember that a feature can
only be classified as being physical if it is not
created by humans. This means that features such
as agricultural crops and man-made dams, are
considered to be cultural features. - Cultural features are those which have been made
by humans. The most obvious examples are
settlements (towns and cities), transportation
systems (road, rail, sea and air) and industry
(mining and agriculture etc). Since cultural
features have often been constructed by humans
using resources from the physical environment, it
is not always easy to distinguish between the
two. A park, for example, is classified as a
cultural feature. Despite often comprising
natural vegetation and wild animals, a park is
constructed (or set aside) by humans for the
purpose of recreation. -
