An Overview of GIS-RS Applications for Archaeological and Cultural Heritage under the DBAR-Heritage Mission

Abstract

In recent decades, the application of GIS and RS in archaeological and cultural heritage (ACH) has witnessed a notable surge both in terms of quantity and scope. During the initial implementation period (2016–2021) of the Digital Belt and Road Heritage (DBAR-Heritage) working group, several instances of GIS-RS-based applications in support of cultural heritage conservation have merged. In this paper, in order to discuss the great potential of GIS and RS on the Silk Road, an overview of GIS- and RS-based applications in ACH is first presented. In a substantial portion of the published scientific literature, the identification and comprehension of archaeological sites, the monitoring and risk assessment of cultural heritage, and the management and visualization of cultural heritage data are highlighted. Following this, five illustrative case studies from the DBAR-Heritage working group are presented to exemplify how the integration of GIS and RS serves as key approaches in recognizing and appreciating cultural heritage. These selected case studies showcase the utilization of multi-source data for the identification of linear sites; detailed, refined monitoring and assessment of the Angkor Wat heritage; and the reconstruction of the Silk Road routes. These instances serve as the cornerstone for highlighting current trends in GIS and RS applications in ACH along the Silk Road. These methodologies efficiently integrate multi-source geospatial data and employ multidisciplinary approaches, ultimately furnishing sophisticated and intelligent tools for the exploration and management of archaeological and cultural heritage in the era of Big Earth Data. Subsequently, a comprehensive discussion on the merits and challenges of GIS and RS applications in ACH is presented, followed by an exploration of the current application trends. Finally, the prospects for the widespread application of GIS and RS in ACH along the Silk Road are outlined in accordance with the operational plan of DBAR-Heritage during its second implementation phase.

A study on the visual defensive system of the Moluo Tower Village, Western China, based on a multi-dimensional model

“…Therefore, we reconstructed a multi-dimensional spatial model and proposed a visual analysis method based on the relationships between individual and combined defense structures. It is an applied study of settlement areas and military contexts [30] to a more comprehensive and integrated assessment of the authenticity and likelihood of a landscape heritage [31,32].…”

3D WebGIS for Ephemeral Architecture Documentation and Studies in the Humanities

“…Introduction 1.1. From GIS to 3D WebGIS for the Humanities Geographical information system (GIS) platforms have been proven to be an effective analysis tool not only in different fields, especially in cultural heritage (CH) [1][2][3], but also in studying historical data (like maps, drawings, and statistical data), becoming historical GIS (HGIS) [4]. Having data stored in a structured way, as in GIS, allows the performance of queries on large records that could be challenging for a human, demonstrating effectiveness in analyzing phenomena's evolution over time, such as in the cases of historical earthquakes [5] or political boundaries changing [6].…”
