When contacted, surveyor general of India Swarna Subbarao said it would take 10 days to draw the Telangana map after getting details from the MHA.
The Survey of India - the national survey and mapping organisation of the country under the department of science and technology tasked with printing of new maps of India with 29 states - is yet to get the final drawings of some mandals merged into Andhra Pradesh with regard to the Polavaram project, the official added.
The Union government had last week promulgated an ordinance merging some villages and mandals of Khammam district in Telangana with Andhra Pradesh (Seemandhra) in a bid to deal with resettlement and rehabilitation of those displaced by the Polavaram project.
The ordinance enables land-for-land in the same revenue division where people will be displaced. Poonam Malakondaiah, principal secretary of school education, meanwhile, said they are yet to get an official map which would be incorporated in school text books. Sources in the school education department said this year all the text books in Telangana will also have a syllabus on Andhra Pradesh (undivided) as they were printed much earlier.
