Space Archaeology and the Management of Terrestrial and Underwater Archaeology through Remote Sensing and LiDAR Carlos Eduardo Thompson Alves de Souza Abstract This paper examines the application of Space Archaeology, Remote Sensing, and LiDAR technologies in the detection, documentation, and management of terrestrial and underwater archaeological sites.

Introduction Archaeological research has undergone a significant transformation through the integration of geospatial technologies. Space Archaeology refers to the use of satellite platforms and aerial observation systems for the detection and analysis of archaeological features on the Earth’s surface and underwater. Remote Sensing provides multispectral and radar data that allow the identification of anomalies associated with past human activity. LiDAR (Light Detection and Ranging) complements this by generating precise topographic models capable of penetrating vegetation cover and shallow water, revealing otherwise inaccessible archaeological information. These methods contribute not only to site discovery but also to long-term monitoring and management strategies for cultural heritage preservation. 2. Materials and Methods 2.1 Remote Sensing High-resolution satellite imagery (optical, multispectral, hyperspectral, and radar) was analyzed to detect geomorphological and anthropogenic anomalies. This included the identification of ancient settlement patterns, landscape modifications, and submerged features. Data were processed using standard image enhancement and classification techniques to improve archaeological feature visibility. 2.2 LiDAR Surveys Airborne and terrestrial LiDAR systems were employed to acquire three-dimensional topographic data. Point clouds were processed to generate Digital Terrain Models (DTMs) and Digital Surface Models (DSMs). These datasets enabled the detection of buried structures, paleo-channels, and submerged landscapes, even in densely vegetated or sedimented contexts. 2.3 GIS-Based Integration All Remote Sensing and LiDAR datasets were georeferenced and integrated into a Geographic Information System (GIS). Spatial analysis tools were applied for feature extraction, pattern recognition, and predictive modeling. This integration facilitated systematic documentation, spatial correlation, and heritage management planning. 3. Applications 3.1 Terrestrial Archaeology Spaceborne and airborne datasets allowed the detection of ancient urban grids, road systems, fortifications, agricultural terraces, and other anthropogenic structures. In heavily forested regions, LiDAR proved especially effective in revealing topographic signatures hidden beneath vegetation. 3.2 Underwater Archaeology Bathymetric LiDAR and satellite-derived bathymetry were applied to identify submerged landscapes, paleoshorelines, and shipwreck sites in shallow coastal waters. These methods provide essential baselines for understanding prehistoric coastal occupation and maritime trade routes. 3.3 Cultural Heritage Management The integration of geospatial data supports the creation of digital archaeological inventories, vulnerability assessments, and monitoring systems. These tools are fundamental for designing sustainable conservation policies, especially in areas affected by urban expansion, agriculture, or climate change. 4. Discussion The combined use of Remote Sensing and LiDAR represents a paradigm shift in archaeological prospection. These methods allow for large-scale, non-invasive data acquisition and analysis, reducing the need for extensive ground surveys. However, challenges remain regarding data resolution, interpretation accuracy, and the integration of interdisciplinary datasets. Continued technological development and methodological standardization are necessary to enhance the reliability and applicability of these approaches. 5.

Space Archaeology and the Management of Terrestrial and Underwater Archaeology through Remote Sensing and LiDAR

Carlos Eduardo Thompson Alves de Souza

Abstract

This paper examines the application of Space Archaeology, Remote Sensing, and LiDAR technologies in the detection, documentation, and management of terrestrial and underwater archaeological sites. By integrating satellite data, aerial imagery, and laser scanning, it is possible to identify buried structures, submerged landscapes, and cultural patterns with high spatial accuracy. These technologies provide essential tools for non-invasive archaeological research and for the sustainable management of cultural heritage in rapidly changing environments.

1. Introduction

Archaeological research has undergone a significant transformation through the integration of geospatial technologies. Space Archaeology refers to the use of satellite platforms and aerial observation systems for the detection and analysis of archaeological features on the Earth’s surface and underwater. Remote Sensing provides multispectral and radar data that allow the identification of anomalies associated with past human activity. LiDAR (Light Detection and Ranging) complements this by generating precise topographic models capable of penetrating vegetation cover and shallow water, revealing otherwise inaccessible archaeological information.

These methods contribute not only to site discovery but also to long-term monitoring and management strategies for cultural heritage preservation.

2. Materials and Methods

2.1 Remote Sensing

High-resolution satellite imagery (optical, multispectral, hyperspectral, and radar) was analyzed to detect geomorphological and anthropogenic anomalies. This included the identification of ancient settlement patterns, landscape modifications, and submerged features. Data were processed using standard image enhancement and classification techniques to improve archaeological feature visibility.

2.2 LiDAR Surveys

Airborne and terrestrial LiDAR systems were employed to acquire three-dimensional topographic data. Point clouds were processed to generate Digital Terrain Models (DTMs) and Digital Surface Models (DSMs). These datasets enabled the detection of buried structures, paleo-channels, and submerged landscapes, even in densely vegetated or sedimented contexts.

2.3 GIS-Based Integration

All Remote Sensing and LiDAR datasets were georeferenced and integrated into a Geographic Information System (GIS). Spatial analysis tools were applied for feature extraction, pattern recognition, and predictive modeling. This integration facilitated systematic documentation, spatial correlation, and heritage management planning.

3. Applications

3.1 Terrestrial Archaeology

Spaceborne and airborne datasets allowed the detection of ancient urban grids, road systems, fortifications, agricultural terraces, and other anthropogenic structures. In heavily forested regions, LiDAR proved especially effective in revealing topographic signatures hidden beneath vegetation.

3.2 Underwater Archaeology

Bathymetric LiDAR and satellite-derived bathymetry were applied to identify submerged landscapes, paleoshorelines, and shipwreck sites in shallow coastal waters. These methods provide essential baselines for understanding prehistoric coastal occupation and maritime trade routes.

3.3 Cultural Heritage Management

The integration of geospatial data supports the creation of digital archaeological inventories, vulnerability assessments, and monitoring systems. These tools are fundamental for designing sustainable conservation policies, especially in areas affected by urban expansion, agriculture, or climate change.

4. Discussion

The combined use of Remote Sensing and LiDAR represents a paradigm shift in archaeological prospection. These methods allow for large-scale, non-invasive data acquisition and analysis, reducing the need for extensive ground surveys. However, challenges remain regarding data resolution, interpretation accuracy, and the integration of interdisciplinary datasets. Continued technological development and methodological standardization are necessary to enhance the reliability and applicability of these approaches.

5. Conclusion

Space Archaeology, Remote Sensing, and LiDAR offer unprecedented opportunities for the identification, analysis, and protection of terrestrial and underwater archaeological sites. Their integration into heritage management frameworks enables more effective conservation strategies and contributes to the understanding of cultural landscapes on a regional and global scale.
