Historical Relics Mapping | Geosun GS-130X UAV LiDAR Scanning System

 Heritage Conservation Mapping at Devin Castle, Slovakia

Powered by Geosun GS-130X UAV LiDAR Scanning System

Project Overview

Geosun's GS-130X UAV LiDAR system was deployed to capture detailed 3D data of Devin Castle, a prominent historical monument located near Bratislava, Slovakia. The mission focused on documenting the fragile medieval architecture and terrain with high accuracy, supporting conservation and digital preservation efforts.

Site Challenges

• Ruins on a steep cliff with complex terrain and obstructed sightlines

• Fragile stonework requiring non-contact survey methods

• Limited accessibility to some upper structures

• Variable light and shadow conditions affecting visual data collection

Flight Configuration

• Flight Height: 50–80 m AGL (above ground level)

• Speed: 6 m/s

• Scan Overlap: 45%

• Effective Range: Up to 120 m

• Point Cloud Density: Over 120 pts/m²

• RGB Camera: 26 MP integrated

Technical Highlights

• High-definition point cloud acquisition preserved fine architectural details of stone walls, arches, and battlements

• Multi-angle scanning captured obscured and collapsed areas

• Combined visual + LiDAR data enabled textured 3D models for virtual tour applications

• Accuracy: RMS < 5 cm; positional deviation < 3 cm in complex vertical areas

Project Outcomes

• Generated a complete digital twin of the castle ruins

• Provided data for structural risk analysis and terrain shift monitoring

• Supported interactive educational tools and cultural tourism platforms

• Facilitated pre-conservation planning through precise 3D measurements

Client Feedback

"This LiDAR scan gave us a full digital replica of the castle, even in hard-to-reach cliffside ruins. It's an invaluable tool for both preservation and public engagement."
