Question

What information does the toposheet number (like 45D/7 and 45D/10) give?
(A) It gives an idea as to which part of India is being depicted by the map
(B) It gives information about the government schemes
(C) It gives information about the impact of climate change on water bodies
(D) None of these

Answer 1

Hint: A topographical map is a map of a small area drawn on a large scale representing detailed surface features both man-made and natural. Relief is shown by contours in this map.

Complete step-by-step solution:
The topography is the study of features and forms of land surfaces. The topography of an area could refer to the surface features and forms, or a description. In a narrow sense, topography involves the identification of specific landforms, the recording of relief or terrain, and the three-dimensional quality of the surface.
All toposheets contain a table showing conventional signs and symbols used in the map and these conventional signs and symbols are internationally accepted. A topographic sheet is usually interpreted under Marginal Information, relief of the area, the drainage of the area, land use, transport and communication, settlement, and occupation. Out of these, minimal Information incorporates the network references, geological sheet number, its area, its degree in degrees and minutes, the areas covered, scale, and so on. In both the upper right and lower left areas of the margin, the toposheet number is found in bold print. The Sheet number helps us to understand the geographical extent covered by the sheet, as to which of India is depicted by the map. It also indicates the map scale.

Thus, option (A) is correct.

Note: Topographical maps, also known as general-purpose maps, are drawn at relatively large scales. These maps show important cultural and natural features. The topographical maps in India are set up in two series, i.e. the International Map Series of the World and India and Adjacent Countries Series.
