3. What is map
Maps are pictures of the Earth's surface. They show how places are related to
each other by distance, direction, and size. Maps are a way of showing a part
of the Earth's surface on a flat piece of paper.

Cultural MAP

8.  If well constructed it shows distribution and comparative
densities
 It is easier to show variation in distribution of wide variety of
commodities if it is presented using different colours.
 Dot maps are used to represent wide range of items like
population, value of minerals, crops and so forth
 They are very easy to construct compared to proportional circles
 It is very easy to compare the distribution of items considering
the concentration of dots.
 It is easy to interpret by counting the number of dots multiplied
by the dot value to get the total value of the given area
Advantages of maps

9.  It is time consuming especially when marking dots on maps
 When the scale is small many dots are drawn which cause
overcrowding and present difficult in counting them to get the
actual value
 In case even distribution of dots is displayed on the map, false
impression that the distribution is the same in represented area
is perceived. This perception may be false
 Locating dots on map is to the certain extent a personal and
subjective decision and two dot maps done by two people using
the same data will rarely be identical
 Construction of dot maps involves tedious calculation especially
when determining number of dots
Disadvantages of maps

10.  scale
 projection
 conventional sign
 skill of the draughts map
 methords of the map making
