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.

Entities of a Cadastral Database

• 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)

Resurvey Probable Issues

• Data Anomalies
• Data redundancy (e.g. multiple records)
• Data inconsistency (e.g. missing land parcels
  new parcels)
• Geometry problems
• Field Issues
• Farmers presence
• Sub-divisions
• Monument tampering
• Non-acceptance of Notices

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

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
