India Uses AI and Drones to Boost Heritage Conservation

India’s rich cultural legacy is increasingly being preserved through a blend of traditional conservation practices and modern technology. The government is strengthening heritage protection efforts by equipping the Archaeological Survey of India (ASI) with advanced tools such as Artificial Intelligence (AI), drones, and digital mapping systems. This hybrid approach is helping improve documentation accuracy, enhance restoration quality, and ensure long-term preservation of the country’s historical monuments.

Expanding Scope of Heritage Conservation in India

Vast Network of Protected Monuments

The Archaeological Survey of India (ASI) currently safeguards 3,686 centrally protected monuments, supported by strengthened conservation systems, scientific restoration methods, and modern technologies such as AI, an official fact sheet said on Saturday.

This extensive network includes temples, forts, mosques, archaeological sites, and colonial-era structures that represent India’s diverse cultural and historical timeline.

Rising Global Recognition

India’s global heritage profile has expanded, with 44 UNESCO World Heritage Sites, including the recent addition of the Maratha Military Landscapes.

This growing recognition highlights India’s efforts to preserve and promote its cultural assets on the global stage.

Digitisation and Scientific Conservation

 Building National Heritage Databases

“Heritage and monument preservation has advanced through large-scale digitisation, the creation of national heritage databases, and the wider adoption of scientific and digital tools for documentation and conservation,” the fact sheet said.

Digitisation initiatives have enabled authorities to create detailed records of monuments, including structural data, historical context, and conservation status. This helps in better planning and monitoring of restoration work.

Scientific Restoration Techniques

There has been a growing use of scientific laboratory techniques to:

• Analyse heritage materials
• Study deterioration patterns
• Identify suitable conservation methods

These approaches ensure that restoration efforts are both precise and sustainable.

Technology as a Key Pillar of Conservation

Integration of Advanced Tools

Notably, technology has become an increasingly important pillar in India’s conservation ecosystem, complementing ASI’s traditional practices with tools that enhance documentation, diagnostics, and long-term preservation.

Modern technologies such as LiDAR scanning, GIS-based mapping, and drone-based surveys are being used, as required, for accurate documentation.

Precision Mapping and Monitoring

“In parallel, India has expanded the application of digital and spatial technologies that support accurate recording and proactive conservation planning,” the statement added.

Key tools now used include:

• 3D laser scanning
• Photogrammetry
• Drone-based surveys
• Geographic Information Systems (GIS)-based mapping

These technologies allow conservationists to detect structural changes, assess risks, and plan timely interventions.

Role of Artificial Intelligence in Heritage Preservation

Enhancing Data Processing and Accessibility

In addition to these technologies, the government has begun integrating Artificial Intelligence (AI) into the broader cultural and heritage ecosystem, particularly in areas such as digitisation, documentation, and accessibility of cultural assets.

AI-enabled platforms are being used to:

• Process large volumes of heritage data
• Organise manuscripts and cultural knowledge systems
• Improve digital access through language technologies

Improving Public Engagement

AI tools are also helping make heritage more accessible to the public by enabling multilingual interfaces and interactive digital platforms, thereby bridging the gap between historical archives and modern audiences.

Collaboration with Scientific Institutions

Strengthening Research Partnerships

Drone-based surveys have also been undertaken in collaboration with institutions such as the National Institute of Science Education and Research (NISER), demonstrating the integration of scientific institutions into heritage conservation efforts.

Such collaborations bring technical expertise and innovation into preservation projects, improving efficiency and outcomes.

India’s Growing Global Heritage Presence

Showcasing Cultural Confidence

“India’s growing presence on the global heritage map reflects the country’s ability to present its cultural legacy with renewed confidence,” the statement said.

Aligning Tradition with Innovation

By combining traditional conservation methods with cutting-edge technology, India is setting an example of how heritage preservation can evolve in the digital age while maintaining authenticity.

Conclusion

India’s approach to heritage conservation is undergoing a significant transformation. By integrating advanced technologies such as AI, drones, LiDAR, and GIS with time-tested restoration practices, the government is ensuring that its cultural treasures are preserved for future generations. With growing global recognition and continued investment in innovation, India is not only protecting its past but also redefining how heritage can be documented, studied, and experienced in the modern world.
