2. INTRODUCTION
•You have been dealing with maps since you were in
primary, classes.
•In Geography, you have been asked to locate a particular
State, a particular river, a mountain etc., on a map.
•In History, you might have been asked to locate a
particular place where some event had occurred long
back.
•You have traced routes of rivers, roads, railway lines,
traders and many others.

3. •How do we read maps?
•What can we conclude and understand while reading a
map?
• What information does a map have and what it does not
have?
• Is it any different from a picture?
• In this section, we will try to find answers to some of
these questions. Look at the map of a house whose picture
is given alongside.
LET US SEE

4. MAPS

7. Colors used in Map
a. Black. Indicates cultural (man-made) features such as
buildings and roads, surveyed spot elevations, and all
labels.
b. Red-Brown. The colors red and brown are combined to
identify cultural features, all relief features, non-
surveyed spot elevations, and elevation, such as
contour lines on red-light readable maps.
c. Blue. Identifies hydrography or water features such as
lakes, swamps, rivers, and drainage.
d. Green. Identifies vegetation with military
significance, such as woods, orchards, and vineyards.

8. e. Brown. Identifies all relief features and elevation,
such as contours on older edition maps, and cultivated
land on red-light readable maps.
f. Red. Classifies cultural features, such as populated
areas, main roads, and boundaries, on older maps.
g. Other. Occasionally other colors may be used to
show special information. These are indicated in the
marginal information as a rule

9. SYMBOLS USED IN MAPS

10. Scales used in Maps
A map is a scaled graphic representation of a portion of
the earth's surface.
The scale of the map permits the user to convert
distance on the map to distance on the ground or vice
versa.
The ability to determine distance on a map, as well as
on the earth's surface, is an important factor in planning
and executing military missions.
Scale is reported as a representative fraction with the
map distance as the numerator and the ground distance
as the denominator.
Representative fraction (scale)= map distance / ground

11. Scales used in Maps
-Distances Shown on the map are proportional to the
actual distance on the ground.
-While drawing a map, we should take care about: How
much of actual distance is denoted by 1mm or 1cm in the
map
-It can be : 1cm = 1 Kilometers or 10 Km or 100Km etc.
-This scale can vary from map to map but not with in the
map.

12. Map Scale Classification
Small Maps 1:1,000,000 and smaller
Medium 1:1,000,000 but smaller than 1:75,000
Large 1:75,000 and larger

18. Points to remember
• A map depicts the location of a particular object/ place in
relation to other objects/places.
• Symbols and colors are used to depict the different
objects/places.
• There is no reference or perspective in map, i.e., objects
that are closer to the observer are shown to be of the same
size as those that are farther away.
• Maps use a scale which is fixed for a particular map. It
reduces the real distances proportionately to distances on
paper.
