shows the major physical features of an area, such as rivers, mountains, vegetation and elevation.
Show the major boundaries
between countries or states.
Shows political boundaries from the past.
With a historical map, you should pay close
attention to the names of countries, political borders,
and the location of cities. T
hese may be different
than they are today.
Show information relating to a
, for example: the spread of a religion or trade routes
Shows where people live
in a specific area.
POPULATION DENSITY MAP
Shows the major natural resources
and agriculture and industrial
products of an area.
RESOURCE OR PRODUCT MAP
Tools of Geography
Geoography uses scientific approaches to examine
where things are located.
it analyzes sounds
to determine distance
Remote sensing technology
Scientist can compare older
and more recent images to
identify changing in land use,
vegetation , and urban growth.
satellites broadcast extremely accuate time meausrements, and it is used to provide information about location.
uses computer technology to collect, manipulate, analyze, and display data about the earth's surface in order to solve geographic problems.
three-dimensional representations of the Earth.
Not very practical or portable
much of the time
Maps , which are 2-dimensional & easier to use
but give a
b/c the earth’s surface is flattened to create the map.
maps have evolved
through the ages, the
function has remained the same—
they continue to be u
sed to show Locations of places, landforms,
and bodies of water, & where
they are in relation to other
parts of the earth.
Other tools used by Geographers
Geographers also use photos, models, cross sections, and many other tools for analysis
shows natural and man made features
are mostly used by sailors or pilots
a series of satellites orbiting 100 miles above the earth.
Geostaionary Operational Environmental Satellite :
a weather satellite
GPS was originally developed by the military
24 satellites called Navstars
to beam info to earth. The exact position--latitude, longitude, time, and altitude—is displayed on a hand-held receiver
to the user.
Another Locator finder is the Magnetic compass introduced by the Chinese around the 1100’s helped to accurately determine direction,
shows lines and shape of a region
since the first satellite was sent into orbit in the 1950's scientist and geographers have been using Satellites to see the earth
The Science of Map Making
1. Survey the land:
Map Maker is called a CARTOGRAPHER
