Background of Land Survey in Gujarat….Background of Land Survey in Gujarat…. Gujarat State is pioneer in the country having it’s Gujarat State is pioneer in the country having it’s survey records up to land parcels known as survey records up to land parcels known as TippanTippanss

Land Survey was carried out long ago by Britishers Land Survey was carried out long ago by Britishers and old Princely States of Gujarat during and old Princely States of Gujarat during 1880 1880 to to 19151915 . .

The object of the survey was to collect Land Revenue The object of the survey was to collect Land Revenue from the owner of land in proportion to the area they from the owner of land in proportion to the area they held.held.

As per As per The Bombay Land Revenue Code, 1879The Bombay Land Revenue Code, 1879 survey survey should have been conducted after 30 years of original should have been conducted after 30 years of original survey. survey.

GujaratGujarat pioneer introducerpioneer introducer

• Gujarat is pioneer in introducing modern survey technology

• ETS since 1990-1991• GPS since 1999-2000

• Using this ETS technology approx. 250 villages have been re-surveyed

• Using GPS technology approx. 30000 hectares of land have been surveyed
