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.

IIC Technologies Private Limited QC Systems # 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   IIC Technologies Private Limited

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) IIC Technologies Private Limited

Interests outgrow the parcel extent Planning Zone Noise Restriction Mining Lease Heritage Protection Area For the individual enjoying the Rights, the extents are limited by the perimeter of the parcel. Exploitation opportunities may not always align with individual land parcels.
