(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
