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
PAPYRUS
PARCHMENT
• 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.
PLAN
DETAILED DRAWING OF A SMALL AREA
PLAN SHOWS A SMALL AREA ON A LARGE SCALE
EG- INTERIOR OF HOUSE , AN OFFICE BUILDING OR
EVEN YOUR CLASS ROOM
MAP SHOWS A LARGE AREA ON A SMALL SCALE
