Noida originally consisted of around 81 villages, but now comes under the Gautam Buddh Nagar district of Uttar Pradesh.

Still, Noida villages lack permanent postal and individual address but according to officials, the homes in villages will be soon mapped using aerial imagery captured by drones designed by North East Centre For Technology Application and Reach (NECTAR), an autonomous society set up under the Union government's department of science and technology. These maps will also provide crucial information about rural areas in an emergency. Officials said it will take almost a year to complete mapping and allotting addresses to all 81 villages.

With houses getting mapped and being allotted a formal address in Noida villages, procuring information on land rights, development plans, etc. will become easier. "Easily available maps will also be helpful in advancing development plans and settling disputes over bordering parcels of land. Mapping will also ease land transfers, by creating reliable maps and title documents."
