    1. LandInformation System Brief Presentation on the Technical Guidelines/ Methodology for Implementation of The National Land Records Modernization Programme (NLRMP) Pan India Consultants Pvt Ltd ( An ISO 9001 : 2000 Certified Company ) Confidential www.panindiagroup.com

    2. 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 Confidential www.panindiagroup.com

    3. 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 : • 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

    4. PIC • Geographical Information System (GIS) and Land Records? • Relating "legal" description of property to coordinate-based systems • To highlight / & then minimize ambiguous or overlapping boundaries • Complex attribute relations • Finally access to public Confidential www.panindiagroup.com

    5. PIC Concept for a Multipurpose LIS Confidential www.panindiagroup.com

    6. PIC DIGITISATION & GEO-REFRENCING and linking of RoR data ofVILLAGE CADASTRAL MAPS Confidential www.panindiagroup.com

    7. PIC • Process • Collecting hardcopy maps/sheets from the concerned Land Record Department • Indexing & Coding • Scanning of Village/Cadastral map sheets • Grid base generation or • Map grid generation • Grid correction of Cadastral images • Digitization of individual scanned Village map sheets(grid corrected) • Edge Matching and Mosaicing up to Village Level • Cleanup and topology building • Quality Control/Checks- Rectify errors • Data Translation-GIS environment • Georeferencing of individual villages, mosaicing up to tehsil/district/state level • Quality assurance • Final deliverables Confidential www.panindiagroup.com

    8. Indexing & Coding and Scanning of Input Maps For scanned output *.tif will be coded as per Census 1991/2001 (DDTTRRHHHVVVnn) as refer in Table: Coding and Indexing. PIC Confidential www.panindiagroup.com

    21. PIC Alternate Approach followed for scanning of Input Maps Confidential www.panindiagroup.com

    22. PIC Sheet wise scanned output of Cadastral Maps of a Village Confidential www.panindiagroup.com

    23. PIC Grid used to minimize scanning distortion/input errors Grid 1:1 Confidential www.panindiagroup.com

    25. PIC Grid overlaid on Cadastral Map Distortion minimized in scanned Cadastral maps using vector grid Confidential www.panindiagroup.com

    26. PIC Rectified/Un-rectified scanned maps –A Comparison Un-rectified scanned map with overlaid grid Rectified scanned map with overlaid grid Confidential www.panindiagroup.com

    27. PIC DIGITIZATION Confidential www.panindiagroup.com

    28. PIC Concept for a Multipurpose Land Information System Confidential www.panindiagroup.com

    29. PIC Concept for aMultipurpose Land Information System Different layers created for different features (poly/line/point etc.) keeping in mind their usage in the GIS data base Confidential www.panindiagroup.com LIS- STANDERDS.DOC

    30. PIC Standard Template & Legend Confidential www.panindiagroup.com

    31. PIC Digitized output of the cadastral map { ekSt+k % MqUMhx<+k }

    32. PIC Final Digitized output with Legend Enlarged View of Legend showing different layers Confidential www.panindiagroup.com

    33. PIC Different sheets mosaiced at Village level Confidential www.panindiagroup.com

    34. PIC Customize QC routine

    35. PIC Check print of the cadastral map { ekSt+k % MqUMhx<+k } Confidential www.panindiagroup.com

    36. PIC ekSt+k % MqUMhx<+k with error report

    37. Digitized out put(1:1 matching) Confidential www.panindiagroup.com

    38. Digitization using dimensions Confidential www.panindiagroup.com

    39. Enlarge view of map generated using dimensions Shift in features Confidential www.panindiagroup.com

    40. 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. Confidential www.panindiagroup.com

    41. Data Translation and linking with RoR data • The data would be converted from AutoCAD 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 RoR.
