Methodology





     The brief methodology of the project is as follows:





                          ❑ Procurement of City Survey maps / sheets from Land Records


                          ❑ Scanning Sheets and Scanning Accuracy Assessment



                          ❑ Creation of ULB wise Grid


                          ❑ Rubber sheet transformation of Scan sheets into Grid



                          ❑ Digitization / Vectorization of City survey sheets, as per standards, in CAD


                               environment.
