4. The art of map - making is called Cartography.
A map is defined as a representation of the whole or
a part of an area. Maps are usually prepared on a flat
surface, but globes are also maps in that they
represent the entire earth.
We commonly use them to communicate graphic
information about places to others. Maps are used
for many purposes in daily life -- to help people
navigate from place to place.
5. TITLEOF A MAP
DIRECTION OF MAP
SCALE OF MAP
MAP PROJECTION
LEGEND OR INDEX OF MAP
6. Map reading is a life skill,
with a vocabulary all its own!
13. The map key (or legend) helps identify features
on a map. Popular map keys show elevation,
terrain population, religions, and more.
14.
15. To help locate places on a map,
we use lines of latitude and longitude
16. Latitude:
is shown on a map as a horizontal line.
Lines of Latitude are parallel lines.
They go around,
but never intersect each other.
17. The Equator is a line of
latitude which is the
midway point between
the northern and
southern hemispheres
18. Longitude: is a vertical lines
drawn on a globe or map.
The long lines goes top to bottom.
Lines of Longitude
measure distance
in East
to West direction
19. Meridian is a line of longitude
Prime Meridian is zero degree
longitude, the first line of longitude
23. 1. Place 1 on the Equator. Place 1A North of the Equator. Place 1B South of the Equator.
2.The degree of Longitude which goes through the center of North America ______, South
America ____.
3.The degree of Latitude which goes through the center of Asia ______, Africa ____.
4. Place an X on the map where 40 North Latitude and 70 East Longitude meet (intersect).
5. Place an O where 20 South Latitude and 40 West Longitude meet (intersect).

24. A map should include the following components namely,
the title, scale, direction, grid system, projection, legend,
conventional signs and symbols.
TITLE OF MAP
It indicates the purpose or theme of the map. Example: Pakistan
– Physical,World – Political, Islamabad –Transport.
Scale
Scale makes it possible to reduce the size of the whole earth
to show it on a piece of paper.
A scale is a ratio between the actual distance on the map to
the actual distance on the ground.
25. Direction
Maps are drawn normally with north
orientation. North direction in a map is always towards the North Pole of the earth
Grid System
The location of a place can be simply defined by its latitude and longitude. In normal
practice, latitude is stated first and then comes the longitude.The latitude and
longitude of a place can be expressed in units of degree, minutes and seconds.
Map Projection
A map projection is a way of showing the spherical shaped earth on a flat piece of paper.
Legend
The legend of a map helps to understand
the map details which are placed at the left or right corner at the bottom of the map
26. 1. Brown: land or earth features - contour lines, eroded areas, prominent rock
outcrops, sand areas and dunes, secondary or gravel roads.
2. Light Blue: water features -
canals, coastlines, dams, lakes, marshes, swamps and levees, ponds, rivers and
water towers.
3. Dark Blue: national waterways

5. Black: construction features - roads, tracks, railways, buildings, bridges,
