Question

Study the extract of the Survey of India map and answer the following questions:

1. (a) Give the four-figure grid reference of the settlement at lodpa.
   (b) Give the six-figure grid reference of the spot height ·172.
2. (a) Identify the features from the conventional signs, the six-figure grid reference of which is 332963.
   (b) Give the compass direction of Ramsida from Nandotra.
3. (a) Measure the length in kilometres of the masonry dam on the main river in the given map extract.
   (b) Identify the type of road that runs from the Police Station at Dantiwada up to the settlement at Nandotra (Brahmanvas) (grid square 2794). For which purpose is this road used?
4. (a) Calculate the area of the region in sq. km, enclosed within the Eastings 25-35 and Northings 91 to 95.
   (b) State the three types of roads seen in the given map extract. What do they reflect on the type of settlements in the region in the given map extract?
5. (a) State the difference in the pattern of settlement at Dantiwada on the right bank of the main river and the one on the left bank of it.
   (b) What is the main form of irrigation in the area north of Sarod Nala? From what can you infer this source of irrigation?

Answer 1

1. (a) 2991
   (b) 265972
2. (a) Chhatri
   (b) Ramsida lies in south-east direction from Nandotra.
3. (a) The distance on the map is 3.6 cm, scale is 2 cm = 1 km therefore, the length of the dam is 1.8 km.
   (b) The road from the Police Station at Dantiwada to the settlement at Nandotra (Brahmanvas) is a Pack track with a pass. It is a shorter route but cannot be used during the rainy season. It is a path used by pack of animals or by group of humans or both.
4. (a) The total number of grid squares in the area enclosed within the Eastings 25 to 35 and Northings 91 to 95 is 40. The area of one grid square is 1 km × 1 km = 1 sq. km. So, the area of 40 grid squares is 40 sq. km.
   (b) There are three types of roads in the given map extract — metalled roads, cart tracks and pack tracks. This shows that the more developed settlements like Dantiwada, Dhanawad, Jorapura, Marwada are connected by metalled roads and may be towns or cities. The smaller settlements, probably villages are connected by cart tracks and pack tracks.
5. (a) Dantiwada on the left bank of the main river has an essentially linear pattern along the metalled road, whereas Dhantiwada on the right bank of the river has clustered settlement.
   (b) Perennial lined wells are the main source of irrigation in the area north of Sarod Nala. This can be inferred from the conventional symbol of lined wells. The presence of these wells and the yellow wash in the given map extract imply agriculture is the main occupation of the people in this region.
