Tools Against Oblivion: 3D Visualization of Sunken Landscapes and Cultural Heritages Applied to a Dam Reservoir in the Gorges de la Loire (France)

Abstract

Around the world, thousands of reservoir dams have flooded valleys and become concrete symbols of the Anthropocene. These landscapes, as well as material or immaterial cultural heritages, were flooded and thus became invisible, even though they remain in the memories of local populations. Today, alternative technologies can enable inhabitants to reappropriate these lost heritages and, in a way, make them visible again. 3D digital tools can effectively recreate representations of these landscapes and restore the visibility of these underwater heritage sites. In this study, we propose a 3D geographic information system methodology combined with 3D geovisualization to recreate sunken landscapes, and we demonstrate the results using the valley of the Gorges de la Loire in France as an example. We show how developing a historical database can provide a "backup copy" of lost landscapes and cultural heritage sites, enabling populations to safeguard and restore these features in their memory following flooding.

Navigating the Past through an Interactive Geovisualisation-Driven Methodology: Locating a 15th–19th Century Paddy Field as a Source of Agroecological Knowledge

“…However, the contribution of interaction to the synergies between heterogeneous sources and types of information, including local collective memory, and to collaborative knowledge creation depends on the interoperability of information and communication between local actors themselves as well as with researchers [33][34][35]. As several studies note, through the use of highresolution satellite imagery and Participatory Rural Appraisal (PRA) methods and the creation of interactive 3D environments, 3D participatory GIS (3D PGIS) can support interoperability [2,36]. This interactive environment can contribute to the generation of new information and meta-information 3 [3] and highlight the semantic property of information: landscape intelligence, position-functionality within spatial systems.…”

Precision Controllable Reversible Watermarking Algorithm for Oblique Photography 3D Models

“…In the last two decades, 3D modeling based on oblique photogrammetry has become the development trend of 3D urban construction (Chen et al 2022;Lan et al 2022). Oblique photogrammetry technology is widely used in fields such as positioning services, building modeling, protecting cultural heritage, and urban landscape planning due to its high efficiency, wide application scope, and strong sense of realism (Zhang et al 2021;Ying et al 2023;Lin et al 2020;Mazagol et al 2021;Zhang et al 2022). The oblique photography 3D model is a 3D model obtained by using oblique photography technology to capture surface features.…”
