Abstract

Accurate and comprehensive documentation is required for the long-term conservation of heritage buildings. This study aims to integrate the interior and exterior data of the Al-Syuro Cipari Mosque using 3D modelling and a combination of terrestrial laser scanning (TLS) and handheld laser scanning (HLS). Two integration methods were compared — free-net and independent georeferencing — to determine the most effective approach. Data was acquired using a Leica RTC360 TLS for exterior areas and a Leica BLK2GO HLS for hard-to-reach interior areas, particularly the ablution area and the mosque tower. The results showed that both methods successfully integrated the interior and exterior data without any gaps in the transition zones where the architectural elements were clearly defined. Free-net georeferencing produced models with an RMSE of 0.003 m and 66% overlap, whereas independent georeferencing offered greater processing flexibility, albeit with the need for special attention to be paid to systematic errors. Statistical tests revealed no significant discrepancies between the actual dimensions of the objects and the point cloud models in either method. The resulting integrated 3D model can be used to document, maintain and conserve heritage buildings with adequate geometric accuracy.

Abstract

Gua Aul, located in Ciamis Regency, is a cultural heritage site with significant historical and scientific value. To support preservation efforts and digital documentation, this study aims to produce a 3D model of Gua Aul by integrating data from a Terrestrial Laser Scanner (TLS) and an Unmanned Aerial Vehicle (UAV). TLS data was used to map the cave interior with high accuracy and density, while UAV data captured the cave exterior, including the surrounding topographic area. The registration process employed an independent georeferencing method, in which each point cloud was tied to the global coordinate system WGS 84/UTM Zone 49S using GNSS data. The integration of interior and exterior point clouds resulted in a complete 3D model, with geometric validation accuracy showing an overall RMSE of 0.005 m, indicating a very small and acceptable average deviation of the TLS and UAV integration compared to the actual dimensions. This integration result was not significantly different from the actual object size based on a t- distribution statistical test at a 95% confidence level. The resulting 3D modeling is expected to serve as a medium for documentation, education, as well as a foundation for sustainable conservation and management of the cultural site. Thus, the integration of TLS and UAV has proven to be an effective and adaptive approach to supporting the protection of cultural heritage in the future.

Abstract

This study examines the potential of Terrestrial Laser Scanner (TLS) technology in documenting and understanding the characteristics of cave spaces as part of geospatial and cultural heritage. The study was conducted in Aul Cave, West Java, as part of efforts to preserve and interpret underground spaces through a digital spatial approach. Using the Trimble X7 TLS, this research produced a comprehensive three-dimensional representation of the cave structure, including its geometric shape and surface characteristics. The analysis focused on the differences in material properties between natural elements such as stalactites and rock walls, and artificial materials such as cement and paving blocks, based on laser reflection intensity values. Through this approach, the study not only provides precise visual documentation but also opens up possibilities for interpreting the function of cave spaces and indications of past human activity. The results of the study show that TLS is not only effective as a documentation tool but also relevant as a spatial analysis method in archaeological, geospatial, and cultural heritage preservation studies. This approach is expected to encourage broader utilization of digital technology in spatial-based research and the preservation of underground cultural heritage.
