Classification and Application of Digital Technologies in Landscape Heritage Protection
Abstract
:1. Introduction
2. Methodology
- Literature search. The WoS database and CNKI database were searched with the keywords “digital landscape heritage” and “Digital Heritage protection”.
- Literature processing and screening. By screening the search results of the database and eliminating papers that were not consistent with the research theme of this paper, we obtained 429 papers in total. Among them, 281 papers were obtained from the CNKI database, and 148 papers were obtained from the WoS database.
- Data analysis. Firstly, the software Citespace was used to conduct a quantitative analysis of keywords co-occurrence and keyword clustering of the literature, and then we drew the related knowledge graph. Secondly, the popular digital technologies in the field of landscape architecture heritage protection were classified using Excel, and the digital methods and applications for different heritage protection objects were summarized. Thirdly, according to the time sequence analysis of keyword co-occurrence clustering and the timeline diagram of keywords, we analyzed the hot topics and digital technologies of landscape architecture heritage protection over the last 10 years. Eventually, through the analysis of the keywords emergence of digital heritage protection, combined with the relevant social backgrounds and policy theories, the application trend and development mechanism of digital technology of landscape architecture heritage protection for different heritage protection objects were analyzed and summarized.

- (a)
- The stage of data precision. During the period of 2012–2014, owing to policy support, such as “Sponge City” and the “National Park” theory, etc., many ancient buildings, tombs, and some natural features in digital measurement appeared, which compared with the previous traditional measurement method, was more scientific and accurate. Furthermore, they combined GIS, GPS, and other information systems to create a database, which made the legacy data more accurate. In order to match the political intentions of “Updated and Sustainable Cultural Heritage Management”, Trier described a new method for the automatic detection of pit structures in airborne laser scanning data collected with at least five emitted pulses per square meter [82]; Gruetzner used an octocopter equipped with a high-resolution range finder camera to gather information on the topographical setting and morphometry of the rampart [44].
- (b)
- The stage of information systematization. From 2015 to 2017, under the guidance of “Double Urban Repairs” (“Ecological Restoration and City Betterment”), “Rural revitalization”, etc., heritage protection of traditional settlements and ancient villages became the focus of digital heritage research. The concept of “Resilience Landscape” enabled scholars to analyze the risks caused by geological disasters and extreme weather, allowing them to conduct virtual displays through data simulation to carry out preventive protection of heritage and form a relatively complete digital protection system of “collection, restoration and prevention”. Towards the development of The Copernicus Program in support of cultural heritage preservation and management, there is increasing exploitation of Interferometric Synthetic Aperture Radar (InSAR) methods to assess geohazards affecting cultural heritage [5]. As a result, Gupta conceptualized a framework for incorporating spatial and non-spatial knowledge of archaeological sites into a National Archaeological Database [83].
- (c)
- The stage of smart management. From 2018 to 2021, “Smart City” promoted the wisdom development of landscape architecture. Liang proposed that social media are one of the most important platforms to promote the public participation process of urban heritage conservation in the context of rapid urbanization [84]. Inclusion is a key value in the implementation of the “New Urban Agenda” and the achievement of sustainable development goals; Ginzarly proposed a methodology for the analysis of viewpoints location-view scenes-tags data for photos posted on Flickr to provide insights into all facets of the perceived landscape character that identifies people-centered heritage at the city level [58]. Digital protection is not just about the protection of heritage entities, it also pays attention to cultural protection, which through the way of virtual reality, artificial intelligence reproduces collective memory and personal emotion. As a result, the quality of information management and the traditional way of heritage protection were improved. The meaning of cultural heritage has been extended to the concept of “Cultural Landscape”. Demetrescu presented a new perspective for the documentation and representation of cultural landscape that includes not only the structures of the city but also the areas that have not been excavated yet, including the surrounding natural environment [60].
5. Conclusions
- (a)
- Collection and acquisition technology can be used to analyze the characteristics of the remaining elements of landscape architecture heritage, such as rockeries, architectural sketches, and buildings in precise digital models.
- (b)
- Designing the corresponding data system and platform through storage and management technology can repair and store the data in the database to manage the data according to different situations.
- (c)
- Dissemination and sharing technology can simulate the heritage environment, as well as disseminate and share heritage information to the public using new interaction and experience methods.
Notes
- Historic Urban Landscape: “Historic Urban Landscape” is a suitable name for the natural and cultural and material and immaterial historical context and value in all cities. It is not solely suitable for “Historic town”, “Historic city”, and other special protection categories under the city.

M.L scholars in the Heritage and Archaeology in the Digital Age: Acquisition, Curation, and Dissemination of Spatial Cultural To be specific, Heritage Data divide the digital technologies in the protection of cultural heritage into acquisition, curation, and dissemination, which are drawn from the ref. [24].
- Photogrammetry: Cameras and other equipment obtain images of the object and describe the measured results in graphics, images, or models.
- Structure from motion: A technique in which camera parameters are obtained by analyzing image sequences when 3D reconstruction is performed.
- Digital twin: Using physical models and other data, complete mapping in virtual space reflects the corresponding physical equipment.
- Sparse model: Removes redundant variables, retain explanatory variables related to response variables, simplify the model, and retain the most important information in the data set.
- Sparse autoencoder: By calculating the error between the output and input of the autoencoder, the parameters of the autoencoder are constantly adjusted to train the model.
- Compressed sensing: A technique for finding sparse solutions of underdetermined linear systems.
- Synthetic aperture radar (SAR): A high-resolution imaging radar which can obtain high-resolution radar images similar to optical photography in meteorological conditions with very low visibility.
- Multi-temporal: Reflects the characteristics of a group of remote sensing images in time series.
