Context: The central government plans to geo-tag all buildings (residential and non-residential) in the Census 2027.
Relevance of the Topic: Prelims: Concept of geo-tagging, Geo-tagging and governance.
What is Geo-Tagging ?
- Geo-tagging is the process of assigning precise latitude and longitude coordinates to a physical asset, building, or location and linking it to a Geographical Information System (GIS) map.
- It digitally pins a structure or object to its exact place on a map allowing it to be identified, verified, and monitored in real time.
Historical Context and Present Use in India:
- In India, geo-tagging has been used in government schemes such as the Pradhan Mantri Awaas Yojana (PMAY), MGNREGA assets, and other development programmes to ensure transparency and accountability in asset creation.
- For the first time in Census 2027 the government plans to geo-tag all residential and non-residential buildings across the country.
Geo-Tagging in Census 2027:
- Enumerators will geo-tag each building within its Houselisting Block (HLB) using a Digital Layout Mapping (DLM) system. This is a departure from earlier censuses, where hand-drawn notional maps were prepared. Now, layout maps will be automatically generated from geo-tagged building data.
- Census 2027 will be India’s first fully digital census using mobile applications, self-enumeration options, and real-time monitoring through the Census Monitoring & Management System (CMMS).
Benefits of Geo-Tagging:
- Accuracy in Enumeration: Geo-tagging will ensure that all buildings are mapped and counted, reducing the chances of omission or duplication.
- Transparency and Accountability: Digitally tagged assets reduce the possibility of ghost entries and fraudulent claims.
- Policy Formulation: Real-time and location-specific data on housing, amenities, and population distribution will strengthen evidence-based policymaking.
- Disaster Management and Urban Planning: A geo-tagged housing database can aid in evacuation, rehabilitation, and planning for infrastructure and civic services.
- Integration with Other Digital Initiatives: Geo-tagging complements initiatives like Digital India, GIS-based governance, and the Smart Cities Mission creating a unified digital governance framework.
Challenges in Geo-Tagging:
- Privacy Concerns: Citizens may have apprehensions about the government mapping and digitally storing the exact location of their homes.
- Digital Divide: Rural and remote areas with weak internet and digital infrastructure may face difficulties in real-time geo-tagging.
- Data Security: Protecting sensitive location data from cyber threats is a major challenge.
Geo-tagging is a crucial step towards e-governance and evidence-based administration in India. It will help bridge gaps between planning and implementation by providing precise, location-linked, and real-time data.
