  • India’s oldest scientific department, the Survey of India (SoI) — historically tasked with mapping the country — will for the first time rely on drones to map the country.
  • The aim is to map 75% of India’s geography— about 2.4 million sq km of the 3.2 million sq km — within the next two years.

High Resolution Maps

  • Currently the best SoI maps have a resolution of 1:2500, meaning a 1 cm on the map represent 2500 cm on the ground.
  • The maps being prepared, according to senior officials associated with the project will be of 1:500 resolution, meaning 1 cm will represent 500 cm.

Use of Drones

  • The organisation aims to procure about 300 drones — so far about 30 have been sourced — for the gargantuan exercise.
  • However forests, hills and deserts are likely to be left out.
  • As a prelude, the SoI, which is affliated to the Department of Science and Technology (DST), has signed agreements with 6 districts in Haryana, 2 in Karnataka and 2 in Maharashtra to undertake such drone-based mapping exercises.

Significance

  • A major consequence of the drone-based exercise will be the mapping of settled habitations in villages (called abaadi areas in legal parlance).
  • Mapping will create high resolution maps of land in villages facilitating the digitisation of land titles in villages.
  • Based on the availability of accurate maps, residents will finally be able to get property cards as well as proper legal titles to their lands.
