Abstract

The application of remote sensing in archaeology has recently gained widespread recognition, leading to the discovery of numerous significant cultural remains. However, the lack of theoretical data on spectral classification severely constrains the practicability of remote sensing archaeological investigations. In this study, we have collected a comprehensive dataset comprising over 15,000 spectral curves acquired from eight distinct categories of typical archaeological remains in Central China. Machine learning is utilized to conduct an in-depth analysis and classification of the hyperspectral attributes of cultural remains. The feature spectra are preprocessed using the Standard Normal Variable Transform (SNV) and Principal Component Analysis (PCA). A spectral classification model is proposed to improve the accuracy of typical archaeological remains using Support Vector Machines (SVM). The evaluation demonstrated that the SVM exhibited the highest classification accuracy of 99.82%. It was ultimately determined that the most distinguishable bands from ancient cultural remains were in the ranges of 524–553 nm, 663–686 nm, 974–1000 nm, 1092–1114 nm, and 2161–2185 nm. The research provides an important theoretical basis and a scientific method for remote sensing archaeology investigations, which is of great significance in understanding the past and facilitating present sustainable development.
利用机器学习对古代文化遗迹进行高光谱分类
遥感在考古学中的应用最近得到了广泛的认可,导致许多重要的文化遗迹的发现。然而,光谱分类理论数据的缺乏严重制约了遥感考古调查的实用化。在这项研究中,我们收集了一个完整的数据集,其中包括来自中国中部8个不同类别的典型考古遗址的15,000多条光谱曲线。利用机器学习对文化遗存的高光谱属性进行深入分析和分类。采用标准正态变量变换(SNV)和主成分分析(PCA)对特征谱进行预处理。为了提高典型考古遗迹的分类精度,提出了一种基于支持向量机的光谱分类模型。评价结果表明,SVM的分类准确率最高,达到99.82%。结果表明,古文化遗存最易识别的光谱范围分别为524 ~ 553 nm、663 ~ 686 nm、974 ~ 1000 nm、1092 ~ 1114 nm和2161 ~ 2185 nm。该研究为遥感考古调查提供了重要的理论依据和科学方法,对认识历史、促进当今可持续发展具有重要意义。

期刊介绍: The journal ''Remote Sensing Applications: Society and Environment'' (RSASE) focuses on remote sensing studies that address specific topics with an emphasis on environmental and societal issues - regional / local studies with global significance. Subjects are encouraged to have an interdisciplinary approach and include, but are not limited by: " -Global and climate change studies addressing the impact of increasing concentrations of greenhouse gases, CO2 emission, carbon balance and carbon mitigation, energy system on social and environmental systems -Ecological and environmental issues including biodiversity, ecosystem dynamics, land degradation, atmospheric and water pollution, urban footprint, ecosystem management and natural hazards (e.g. earthquakes, typhoons, floods, landslides) -Natural resource studies including land-use in general, biomass estimation, forests, agricultural land, plantation, soils, coral reefs, wetland and water resources -Agriculture, food production systems and food security outcomes -Socio-economic issues including urban systems, urban growth, public health, epidemics, land-use transition and land use conflicts -Oceanography and coastal zone studies, including sea level rise projections, coastlines changes and the ocean-land interface -Regional challenges for remote sensing application techniques, monitoring and analysis, such as cloud screening and atmospheric correction for tropical regions -Interdisciplinary studies combining remote sensing, household survey data, field measurements and models to address environmental, societal and sustainability issues -Quantitative and qualitative analysis that documents the impact of using remote sensing studies in social, political, environmental or economic systems
