11.What are Cadastral maps?, ➢ Cadastral maps are prepared to record the boundaries and ownership details of land, properties, ➢ Eg: Village maps, 12.Define Topographical maps, ➢ Maps that show both natural and man-made features in detail., 13.What are the factors required for the good reading of maps?, ➢ Map reading requires a good knowledge of its scale, direction, and the signs and symbols, used in them., 14.What are the three different methods to show the scale in maps?, ➢ Statement of scale, Representative fraction, and Linear scale., 15.Which among the scales given in the map is easy for us to, Understand? Why?, ➢ Statement of scale, ➢ Even a layman can easily understand this., ➢ Eg:1 cm to 5 km (one centimetre on the map represents 5 km on earth), 16.Can the people of other countries interpret the maps prepared on Indian units with ease? Why?, How will you avoid this problem?, ➢ No., ➢ The units used for measuring distance are different in different countries., ➢ Representative fraction is the ratio between the map distance and corresponding ground, distance expressed in fractional form., ➢ This proportionate distance can be read in accordance with the units followed in each, country, ➢ Eg:1:500000 (While the Indians read this as 1 centimetre to 500000 centimetres, the, Europeans can read this as 1 inch to 500000 inches), 17.What is the merit of using linear scale in maps?, ➢ When a map is subjected to enlargement or reduction, the linear scale will also change, accordingly. This is the merit of this method., 18.How to measure distances on maps?, ➢ To measure straight distance, a ruler can be used., ➢ If it is a curved distance such as a river or a curved path, first measure the distance using a, thread and then measure the length of the thread, 19.What should be done to find the actual distances?, ➢ The map distance should be multiplied with the proportionate ground distance shown in the, map scale, ➢ Eg: Scale of the map is 1cm to 10km. Suppose the distance from A to B in the map is 5 cm., ➢ Then the actual distance from A to B = 5 x10km =50km, 20.Name the agency responsible for making, scrutinising, and, publishing maps in our country.
