As part of a countrywide exercise,the Census Directorate will undertake GIS mapping of 647 statutory towns and 1.06 lakh villages in Uttar Pradesh,which will show each and every house and the number of people living there.

A nodal office set up by here by the Office of Registrar General and Census Commissioner will undertake similar work for Bihar,Jharkhand and Orissa as well. Four such centres have been set up in the country. Hyderabad-based ICC Technology Private Limited has been hired for the work.

“A base map of every district,tehsil and town has been collected from the local bodies of UP,Bihar,Jharkhand and Orissa. In the first phase,we are taking up the statutory towns of UP. Digitisation of towns in other states will be completed in the next four months,” said Vinod Kumar Singh,Senior Geographer at DCO,UP,and nodal officer for digitisation at the Lucknow centre.

Digital maps of 1.06 lakh villages of UP were completed in 2006 but these were not used in Census 2011 and the data of households and people were not linked with these,Singh said. “However,GIS mapping of capital towns in all states was used for the first time during enumeration for Census 2011.”

In Lucknow city,GIS maps of 110 wards were provided to the enumerators during Census 2011.

After GIS mapping of statutory towns,attribute data of human beings and households will be linked with the maps,Singh said. “GIS maps of every ward and enumeration block will be superimposed on the base map collected from local bodies. The differences between the two will be marked on GIS maps. Then a door-to-door survey will be conducted to mark the number of every household,its owner,number of people residing there and size of the building on the maps. Then a final GIS map will be prepared,” Singh said.

The public will be provided these maps offline and online,but they will show only the area of the enumeration block,location of household,distance of roads,direction and total population there. Census officials will be able to see details like the size and area of the household,name of owner,number of people living there and their age.

“The updated GIS maps of enumeration blocks will be used in the next Census 2021. These maps can also be used for various studies like annual health survey,” Singh said.
