  • The office commenced a gradual migration from the analogue era to the digital age
  • It started with the conversion of all its analogue data into the digital environment through the electronic document management system (EDMS).
  • This started in the records unit of the directorate of co-ordination, transaction and records with the scanning of all government and privately practicing surveyor’s plans into a database.
  • Charting which is the procedure carried out for status determination for the preparation of land information certificate and other similar documents is now also done in the digital environment.
  • The front desk for the one stop public enquiry service (OSPES) point under the service charter reform programme of the government has also adopted by default the digital platform as its tool of engagement with members of the public.
  • Efforts are on to carry out all cadastral related activities starting from data capture to data processing which includes but not limited to examination, computation, cartography (plotting) and plan preparation (e – survey) in the digital environment.
  • The state government has also embarked on the preparation of e – certificate of occupancy.
  • As a step forward towards attaining greater efficiency in the performance of its assigned role and responsibilities considering the strategic importance of the office in the economic development of the state, the digital mapping and enterprise GIS project was embarked upon in 2008. The project was completed and commissioned in 2012.
