Cadastral Surveying and Land Records
Cadastral Surveying and Land Records
This domain tests village-level revenue surveying and the records an Amin helps prepare or verify: khasra, khata, khatiyan, jamabandi, chauhaddi and the Bihar Bhumi system. Expect map-reading, area-unit conversion and boundary procedure.
Core rules
- A khasra (plot) number identifies a parcel of land; a khata (account) number groups the plots held by a raiyat. A khatiyan is the record of rights; jamabandi is the register of holdings and rents. Do not treat khasra and khata as the same identifier.
- Chauhaddi means the four boundaries of a plot. Boundary marks and neighbouring plot numbers are recorded so the parcel can be identified on the ground and on the cadastral map.
- A mauza is a surveyed village unit; a halqa is a circle of villages for revenue administration. The Amin records measurements in the units used in the local record.
- Bihar's land-records portal, Bihar Bhumi, provides online access to khatiyan and jamabandi and handles mutation-related services. Parimarjan refers to correction of records; dakhil kharij is mutation after transfer.
- 1 acre = 100 decimal = 4046.86 m². In Bihar, 1 bigha is commonly divided into 20 katha, but local bigha sizes vary, so always use the notified local unit.
Worked example
A khasra is recorded as 0.25 acre. Convert to decimal and square metres: 0.25 × 100 = 25 decimal. 25 decimal × 40.4686 m² = 1011.7 m², approximately 0.1012 ha. If the local record uses katha, do not convert with a remembered standard bigha until you confirm the local conversion; a wrong bigha standard changes the area substantially.
Traps
Do not confuse khata with khasra, or khatiyan with jamabandi. Do not plot a parcel without its chauhaddi and neighbouring numbers. Do not assume one bigha equals the same area in every district. A mutation entry is not the same as a fresh survey measurement.
