HOW DO WE MAP SPACE AROUND US?

When we draw a picture, we attempt to represent reality as it is seen with all its details, whereas, a map depicts only the location of an object, in relation to other objects. Secondly, different persons can give descriptions of pictures completely different from one another, depending upon the position from which they are look at the house. But, this is not true in the case of a map. The map of the house remains the same irrespective of the position of the observer. In other words, perspective is very important for drawing a picture but it is not relevant for a map.

Use of certain symbols and mentioning of distances helps us to read the map easily. Observe that the distances shown on the map are proportional to the actual distances on the ground. This is done by considering a proper scale. While drawing (or reading) a map, knowledge of scale to be drawn (or has been drawn), i,e, how much of actual distance is denoted by 1 mm or 1 cm in the map, should be taken care off. This means, that if one draws a map, he/she has to decide that 1 cm of space in that map shows a certain fixed distance of say 1 km or 10 km.

MAPPING SPACE AROUND US:

HOW DO WE MAP SPACE AROUND US?

A Map always have same scale.
Thus, we can conclude that:
A map depicts the location of a particular object/place in relation to other objects/places.
Symbols are used to depict the different objects/places.
There is no reference or perspectives 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 the paper.
