Solution
(a) The four figure grid reference of: (i) Dadarla -1020 (ii) Bhamra – 0420
(b) Dantrai is the largest settlement shown on the map extract. Post Office (PO) is the one communication facility which is exclusively available to this settlement.
(c) RF stands for Representative Fraction.
RF = `"Distance between two points on the map"/"Distance of the corresponding points on the ground"`
RF of the map is 1:50,000, i.e., 1 unit on the map is equal to 50000 units on the ground.
(d)
Area from North to South = 9.2 cm
Area on Ground will be = `9.2/2 = 4.6` km
Area from East to West on map = 7.3 cm
Area on Ground will be = `7.3/2 = 3.65 "km"`
Total area of the actual ground is
= Area from N to S on ground × Area from E to W on ground
= 4.6 km × 3.65 km = 16.79 sq.km.
(e) Contour interval means the difference between two consecutive contour lines. Contour interval of the given toposheet is 20 metres.
(f) Highest spot height is 339 metres and the lowest is 263 metres.
(g)
(i) Spot height 339 – 042276
(ii) Permanent hut located near Dhad Talao – 077225
(h)
(i) Occupation: The main occupation of the people of this area is agriculture. Yellow colour over the map stands for agricultural land. White patches on the map shows the uncultivated land.
(ii) Religion: The symbol of temple all over the map proves that mostly people belongs to Hindus religion.
(i) Natural source of irrigation is Sukli Nadi. The solid blue circle and hollow blue circle indicates the presence of lined and unlined perennial well as the man-made source of irrigation.
(j) The general mode of transportation is bullock or horse cart. A single red line shown on the map indicates the cart-track. It is a path broader than a pack track, made by bullock or horse cart.
