1. Give short answers:

(a) What do you mean by scale?

Ans: The ratio in which the actual distance between various places on the earth’s surface is reduced is called scale in cartography.

(b) What do you mean by Geographical Information System?

Ans: Geographical Information System is an advanced computer based system to detect and analyse the various features and events occurring on the earth’s surface. The system which collects, checks, analyses and displays the data related to various places on the earth’s surface in a systematic manner is called a Geographical Information System (GIS).

3. Write elaborately on the development in map-making.

Ans: It is not an easy task to develop a meaningful map. Adequate knowledge is required in terms of methods and tools to be used. Man has been trying to draw maps since the beginning of human civilization. The oldest map was found in Mesopotamia (present Iraq). This map was drawn on mud plastering. Such map was produced in Egypt as well. They showed the flood affected areas of the river Nile. It has been found that the Chinese drew maps with scale in the 2nd century B.C. They drew maps to show mountains and hills, rivers, roads etc. on silk clothes. Amongst the ancient scholars, Ptolemy (90–168 B.C.) showed keen interest and skills in drawing map. He tried to determine the location of places with the help of longitude and latitude. Columbus, Vasco da Gama etc. discovered different places and enriched people’s knowledge about the earth.

Invention of printing machines in Europe brought drastic changes in the field of map making. The Industrial Revolution that had originated in Europe gradually spread to all parts of the world. People could tap various types of resources with the help of machineries. Thematic maps were prepared to show distribution of resources, their use etc. Maps were prepared in India from 2500 BC onwards. Emperors and kings in India prepared maps to show the boundaries of their kingdoms. In India the British for the first time applied scientific techniques in the preparation of maps. They established the organization named the Survey of India in the year 1767. In the beginning of 19th century, the Surveyor General of India, William Lenton adopted scientific method for drawing maps. Subsequently, Sir George Everest developed this method further. As mentioned above, nowadays the use of remote sensing technology and computer have enabled to prepare very perfect maps.

4. What technologies are used in the study of Geography?

Ans: Normally, spatial information technology includes Remote Sensing, Geographical Information System (GIS) and Global Positioning System (GPS).
