Challenges of Traditional Methods:

• Restricted Accessibility – Many heritage sites are fragile, remote, or structurally unsafe, limiting ground inspections.
• Risk of Damage – Traditional inspections (scaffolding, physical sampling) risk harming delicate monuments or artifacts.
• Fragmented Historical Records – Traditional 2D documentation does not capture structural details for restoration or digital archiving
• Limited Accuracy: Using handheld measuring tools or depending on ground photos limiting accuracy.
• Visualization and display limitation: constraints in displaying and managing collected data.

With Drone Technology:

• 3D Heritage Documentation & Digital Twins – Enables precise restoration, research, and long-term digital preservation.
• Structural Integrity Assessment – Detection of cracks, moisture ingress, thermal stress on heritage structures.
• Archaeological Site Mapping & Excavation Planning – Guides archaeologists while minimizing invasive digging.
• Visual Pollution Monitoring Around Heritage Sites – Managing surrounding areas to help municipalities maintain aesthetic integrity of cultural landmarks and surroundings.
• Virtual Tourism – Generate immersive virtual tours that expand cultural access globally and generate new tourism revenue streams.
• Virtual Documentation and Restoration – 3D documentation of heritage sites and monuments and adopting specialized software enables digital restoration.
