MAPS AND GLOBES

GLOBES• A globe is a small-scale three

dimensional MODEL OF THE EARTH.

• It is mounted on an axis so that it can e rotated freely just like an earth.

• The line of latitude and longitude are drawn on map.

ADVANTAGE AND DISADVANTAGE OF GLOBE• Shows exact shape of the

earth- spherical slightly flattened at the poles and bulging at the equator.

• The shape f continents and oceans are shown accurately.

• The different physical features are also marked more ore less accurately.

• Bulky and can not be stored easily

• It can not show the details of landforms and location of small towns.

• It can not provide detail information about climate, vegetation agriculture etc.

• Although larger globes show some details they are difficult to carry and handle

MAP • A map is a essential tool of a

geographer.

• It is a representation of a earth as whole or part of the earth drawn on a flat surface.

• It can show continents courtiers cities and even a local area with all details

• A map how ever has a disadvantages.

• A flat map can not accurately show the curved surface of the earth.

• When a map is drawn the shape and size get distorted.

• The maximum distortion occurs in the region of poles and less at equatorial region.• Its not a new phenomenon and has been

practiced since the ancient times. • They were made from animal skin

parchment papyrus and clay tablets

• The science of map making is called as CARTOGRAPHY (Carte- in French means “MAP” graphic- DRAWING).

• A person who draws map is called as CARTOGRAPHER.

• Cartographer show the curved surface of the earth on a flat map is known as MAP PROJECTION.

TYPES OF MAPS

POLITICAL MAPS

PHYSICAL MAP

TOPOGRAPHICAL MAP OR CONTOUR MAP

CLIMATIC MP

TOURIST MAP

THEMATIC MAP

POLITICAL MAPSShows the boundaries of administrative units

such as countries, state and district

Different types of boundary are shown

with different symbols

PHYSICAL MAPShows the landforms and the water bodies on the

earth surface such as mountain, plateaus plains,

rivers lakes, sea etc.

Topographical map shows a great details of both man made and natural features with the help of conventional sins and symbols

Imaginary line joining place above the mean sea level is known as CONTOUR

All over the world it is used by geographers, geologist defense personal and surveyors

Climatic map

• Shows weather condition like temperature, pressure wind direction and rainfall

Thematic map

• Shows the distribution of forest, crops, minerals and vegetation.

USES OF MAP Easy to handle and can

carry everywhere

Provides lots of information for

planning such a road residential complex's

etc.

It is useful to sailors, pilots miners engineers

etc..

Army depend on maps for information

SKETCHRough map is drawn without any scale, conventional sign and symbol, directions and distance.
