PIC Importance of cadastral records and land information systems Access and use of land are fundamental to life as we know it. . . Food, fiber, habitation, recreation, and so forth. Land parcel is the basic unit for access and control of land, land use decisions. Current, reliable land information necessary for many public programs, for example: land planning infrastructure development and maintenance environmental protection and resource management services social service programs and so forth basis for land markets, development, and other economic activity 3/19/2018 Confidential www. panindiagroup. com 2
PIC NLRMP: • Govt. of India has decided to implement the Centrally. Sponsored scheme in the shape of National Land Records Modernization Programme (NLRMP). • The major component of NLRMP are : ü ü ü 3/19/2018 Computerization of Land Records, Integration of spatial & non- spatial/textual information. Strengthening of Revenue Administrations and updating of Land Records(SRA & ULR). Establishment of modern record rooms/ Land Record Management centers at Tehsil/Revenue Circle/District level Confidential www. panindiagroup. com 3

PIC Now the digitized output is ready for: • Processing of digitized data to generate the out put as per the guidelines/specifications provided by LRD. • Check plot generation for verification with original input map. • Incorporation of errors/feedback or other remarks of first QC • Finalization of data & composition of final map. 3/19/2018 Confidential www. panindiagroup. com 40
PIC Data Translation and linking with Ro. R data The data would be converted from Auto. CAD to Arc coverage/shape & Geo database by using data migration tools/customized routines/programme etc. These tools will be designed as per the LRD Specifications. • The list of records/files will be verified to make sure that all the data is converted successfully. As soon as the migration is finished, the created error logs would be fixed. Also check the completeness of the data translation through internally developed software routines. • These routines would ensure that all the features are translated by comparing the source and the target data. After the successful completion of the migration process, it can be noted that all the data is present in the geo-database without losing any information. Feature coding for polygons/lines & points features i. e. preparation of coding scheme for different features present in maps, generation of code for whole tehsil and structure for respective backup table will be built strictly as per NIC/LRD requirement/guidelines for linking of Ro.

PIC Quality Assurance • Verification of naming conventions , scanning, digitization, topological correctness, unique feature coding, completeness of data, accuracy and RMS errors will be checked. • Verification of positional accuracy, attribute accuracy, logical consistency, completeness, edge matching and Mosaicing will also be verified at village and then at tehsil level. • Quality Criteria will be as given below: • Directory/folder structure: 100% • File naming convention: 100% • Data readability: 100% • Data structure: 100% • Data format: 100% • Topology: 99% • Attribute correctness: 98% • Attribute completeness: 98% • Meta data of each stage deliverables 98% 3/19/2018 Confidential www. panindiagroup. com 45
