For the first time Survey of India to deploy 300 drones for mapping country
Survey of India (SoI), the oldest scientific department of country will for the first time rely on drones to map the country. SoI which is India’s National Survey and Mapping Organization is in charge of mapping and surveying entire country. SoI is affliated to the Department of Science and Technology (DST).
- To provide good high-resolution foundation maps. Also, High-resolution maps will facilitate digitisation of land titles in villages.
- To map 75% of India’s geography (about 2.4 million sq km of 3.2 million sq km) within next two years.
To fulfill above objective the organisation aims to procure about 300 drones and so far about 30 have been sourced for the mega exercise.
As a precursor to undertake such drone-based mapping exercises, Survey of India has signed agreements with districts in Haryana (6), Karnataka (2) and Maharashtra (2). Every square kilometre mapped by drones will be encapsulated in 2500 pictures and thus be a store of digital data.
Currently the best SoI maps have a resolution of 1:250000 (i.e. 1 cm on the map represents 2500 cm on ground), however, new maps under the project will have a 1:500 resolution (i.e. 1 cm on map will represent 500 cm).
Other than unprecedented detail, a consequence of mapping will be creating high resolution maps of land in villages thereby facilitating digitisation of land titles in villages.
Sorting rural issues: A major consequence of drone-based exercise will be mapping of settled habitations in villages. Based on availability of accurate maps, residents will finally be able to get property cards as well as proper legal titles to their lands.
