“…The Mogao Caves are a unique site of outstanding value,and they represent an irreplaceable and irreproducible human resource. These caves are inscribed on the World Heritage list since 1987 30 , where we can observe several frescos, mural paintings, and precious statues dated from the fourth to the fifth century, which are located in 492 caves 31 . The Mogao Caves provides and documents precious and exceptional data for numerous fields such as history, art, and archaeology studies.…”

Ancient statues are usually fragile and have a tendency to deteriorate over time, developing cracks, corrosion, and losing color. Before any intervention on the object of art, a conservator must map degradation and take measurements. Deterioration mapping is an extremely long process, as the conservator or restorer must locate and digitize the damages manually and collect physical measurements from the artwork. Extracting and measuring the deterioration automatically from images is less expensive and aids the digital documentation process, thus reducing the time cost of manual deterioration mapping. In this paper, we propose an effective approach named Missing Color Area Extraction in order to extract and measure missing color areas from high-resolution imagery statues, using a thresholding technique. The conversion from RGB color space to HSV color space is applied, in addition to morphological operations to remove the dust and small objects.

The main objective of the work presented here has been to develop an appropriate approach for making a reproduction of a hominid skull, specifically of Homo naledi, the original of which was discovered at the Rising Star cave site (South Africa), and is on display at the University of the Witwatersrand, Johannesburg (South Africa) where it is kept for research. The fragility of the skull made it impossible to carry out a direct molding process on it and, for this reason, digitization and 3D printing techniques have been applied and a second phase that involved carrying out a traditional molding on the impression. The copy of this piece is currently part of the permanent exhibition of the National Museum of Natural Sciences in Madrid. He highlights the importance that 3D techniques present for the field of research, dissemination and conservation of cultural heritage.

“…In general, optical remote sensing is widely used in archaeological prospection [5] and dynamic monitoring of environmental parameters surrounding heritage sites [6] due to its advantages of high spatiotemporal and spectral resolution. LiDAR has been used for archaeological studies in forested areas [1], [7] and for digital heritage documentation [8], [9] due to its capability of 3-D data representation and depiction of microtopography. In contrast, imaging radar is characterized by all-weather data acquisition and subsurface penetration in arid landscapes.…”

In this study, an integrated monitoring and evaluation approach was proposed to fix the systematic safeguarding gap of the Great Wall corridor using space technologies. Two representative sections of the Great Wall located in Qingtongxia County and Zhangjiakou City in China were selected for a preliminary comparative investigation to ascertain the coupling mechanism and spatiotemporal characteristics of the driving forces for the heritage damage. The surface deformation rates were estimated by synthetic aperture radar interferometry, and the interaction between the deformation rates and the normalized difference vegetation index (NDVI) and meteorological and topographic data was calculated using the correlation matrix. The results showed the following: 1) the surface motions along the observed landscape corridor of the Great Wall were decreased in 2015-2018; 2) the correlation coefficients between the deformation rate and the elevation, slope, annual wind speed, and NDVI in Qingtongxia were 0.524, 0.115, 0.582, and 0.522, respectively, indicating the dominant influence of surface runoff and high winds on the degradation of the rammed-earth wall in the western arid regions; vice versa, 3) the correlation coefficients between the deformation rate and the aforementioned factors in Zhangjiakou were 0.065, 0.027, 0.025, and 0.052, respectively, indicating negligible effects of natural processes for the decline of Great Wall in the eastern section. This study not only provides new insights into preventive monitoring and risk assessment of the entire Great Wall but also highlights the potential of space technologies and a geographical perspective for the sustainable conservation of large-scale heritage sites.
