  9. Sy.no 158 has 3 sub-divisions 158p3 Parcel blocks; Adjacency with Govt. Lands IIC Technologies Private Limited

  10. Correlation IIC Technologies Private Limited

  11. From history.. • The field-to-field survey …. thoroughly revised during the past decade, it is final and will never have to be done again • In Bombay and Madras, where what is called the Raiyatwari system prevails, the boundaries of fields or holdings are invariable. • BADEN-POWELL , 1907 LAND REVENUE AND TENURE IN BRITISH INDIA IIC Technologies Private Limited

  12. # QC Sub-system Scope 1 Input QC Checks the collected records (spatial and textual in both soft and hard copy formats) before passing them to Pre-Survey phase. 2 Geodetic Network QC Checks the control point density, accuracy through network closure, observation periods, Monumentation, documenting. 3 Traverse QC Checks the field notes, traverse closures Random field checks for area correctness and attribute completeness. Form-B completeness. 4 Draft LPM QC Checks the proper data ingest to LPM software, spatial and attribute data, plot scale, LPM format, completeness 5 Product QC Checks the completeness in all the generated registers, maps. Checks the plots for symbols, colours, completeness, layers, formats QC Systems IIC Technologies Private Limited

  13. Entities of a CadastralDatabase • The attributes of cadastral objects: • temporal (e.g., value of a parcel) • non-temporal (e.g. name of a village) • The relationships between cadastral objects can be: • spatial (e.g. village-district relationship) • temporal (e.g. Parcel-Khatedar relationship) • spatiotemporal (e.g. Shape-Change with time) IIC Technologies Private Limited

  14. Dynamics IIC Technologies Private Limited

  15. Dynamics: Parcels within Parcels IIC Technologies Private Limited

  16. 2002 ‘05 IIC Technologies Private Limited

  18. Resurvey: Probable Issues Data Anomalies • Data redundancy (e.g. multiple records) • Data inconsistency (e.g. missing land parcels; new parcels) • Geometry problems Field Issues • Farmer’s presence • Sub-divisions • Monument tampering • Non-acceptance of Notices IIC Technologies Private Limited

  19. Observations / Conclusions • Interactions of DB  InterOperability • Design as spatio-temporal database • Use of UTM / WGS84 / MSL height as Control Grid • Maintenance of DB (pro-active, reactive) • Flying of conterminous areas • Unique-id tag for stake-holder IIC Technologies Private Limited

  20. Observations / Conclusions.. • Maintenance of monuments • Village accountant (Talati) • There is no SINGLE/PERFECT cadastral model • Model making in India to begin, evolve • Backbone of NLRMP essential IIC Technologies Private Limited

  21. SOLUTION Observations / Conclusions.. Operations P R O J E C T S C H E D U L E IIC Technologies Private Limited
