forward in mitigation.

• Hence, a topographical map shows the idea of the earth surface
  alongside the places of various items.
• Such a map is fundamental for designing ventures including roads, railways, water system, supplies, municipalities and so forth
• The size of a topographical map relies upon the degree of the
  area it covers, and the reason for which it is to be ready
• For the most part, a topographical map is set up as indicated by
  a size of I cm to I km (i.e, 1//00, 000)
