河南省郑州市的平陶城是东周重要城邑,具有重要的历史价值。由于传统考古调查具有耗时长、投入大、工作量大等问题,平陶故城的聚落布局、遗迹分布等仍不清晰。研究选取Corona和Google Earth历史影像、无人机热红外和高光谱影像,对比分析不同载荷、不同时相、不同尺度影像上的色调和纹理特征,提取平陶城城址的考古异常区域,发现了疑似城墙、城门、角台、长方形房基等遗迹,并根据识别结果初步重建遗址空间结构。研究结果表明,Corona影像有助于识别遗址早期面貌,Google Earth历史影像可以在微小的疑似遗迹特征检测和提取方面提供帮助,航空热红外影像可以揭示在地面或光学影像上不明显的埋藏的考古特征,航空高光谱影像经过最小噪声分离变换有助于探测微弱信息。研究证明综合利用多源高分辨率数据可对遗址遗迹分布、空间结构进行调查、预测和重建,为进一步考古研究和遗址保护提供参考。 相似文献

考古遗址预测模型（SPM）在考古学研究和文化资源管理中有着广泛的应用,但传统的构建方法过度依赖数字高程模型（DEM）,对多光谱遥感数据的应用较少。本项研究以陇东黄土高原地区的区域考古调查为例,利用第三次全国文物普查数据、商业DEM数据和Landsat 8 OLI多光谱遥感数据,构建3种考古遗址预测模型（DEM模型、多光谱遥感模型和混合模型）。研究表明,黄土高原地区先秦遗址分布对坡向、纵向曲率、地形开阔度等地貌因素具有明显的相关性,而引入主成因素分析法（PCA）提取的多光谱因子不仅可以有效提高单纯基于DEM派生数据构建的遗址预测模型的精度和预测效率,而且还能够很好地改善遗址预测模型的空间结构,增强遗址预测模型的应用效果。基于上述混合模型的分析,陇东黄土高原地区先秦时期的土地资源开发,从仰韶文化时期的不足10%,迅速提升至龙山文化时期的43.1%,先秦时期整体达到了57.3%的规模,土地资源的加速开发奠定了该地区早期文明发展的基础。 相似文献

考古勘探是考古研究的重要手段之一,需要对得到的各类史料进行分析、建档、建库等。在考古发掘过程中,要求实现对现场资料完整准确记录、海量考古数据的科学分析与直观形象表达,但是目前考古勘探过程中,大量地使用传统的表格数据作为记录载体,存在遗址范围、出土物影像、形状等非表格类信息难以保存及集中建库管理较难等问题。本文主要针对考古勘探中存在的此类问题,以GIS空间信息作为主要的数据关联,探讨GIS信息与考古勘探信息融合建库的方法以及古地貌数据分析过程中碰到主要问题的解决办法,研究开发了考古勘察综合信息管理系统,基于GIS技术优化考古勘探信息的管理模式,针对考古前期勘探效率低的问题,从系统制作的技术手段到系统的应用,作了详细的介绍和分析。 相似文献

Talakadu is a well known historic place situated on bank of the river Cauvery in Mysore district of Karnataka. The place is
close to concave side of a prominent meander where large amount of sand has accumulated. It is believed that after construction
of a reservoir upstream, sand was exposed to wind action burying the structures of Ganga dynasty and other later kingdoms.
A number of buried sites have been identified by archaeological excavations conducted so far. Presently the area forms sand
dunes with thick plantation cover. Analysis of RADAR data (fine beam RADARSAT and ENVISAT ASAR) led to identifying a hitherto
unknown buried channel through the Old Talakadu town adjoining the excavated archaeological sites. The study suggests that
RADAR penetration through the plantation canopy seems to have occurred as observed by comparing with corresponding optical
data of LISS-IV. Below the canopy, sand and shrubs on top of the channel (topographically low area) are acting as smooth surface
providing dark tone on radar imagery. During field validation GPS was extensively used to navigate through the forest canopy
and locate the buried channel, excavated archaeological sites as well as other anomalous patterns. Synergistic application
of optical (RESOURCESAT-1 LISS-IV and CARTOSAT-1 & 2) and radar (fine beam RADARSAT and ENVISAT ASAR) data led to identifying
remote sensing based guides for archaeological exploration. Integration of known archaeological sites with the identified
anomalous patterns was done in GIS environment. This study adds on to the knowledge base of the site and compliments already
known information and suggested new areas for further archaeological exploration. 相似文献

Abstract Sources of heterogeneous geospatial data such as the elevation, the slope, the aspect, the water network and the current settlements related to the known Neolithic archaeological sites of Magnesia, are used in an attempt to confirm the existence and allow for the prediction of other archaeological sites using predictive modelling theory. Predictive modelling allows the update of the problem solving strategy as soon as new data layers are available. The Dempster–Shafer Theory also commonly referred to as evidential reasoning (ER) is used to compose probability maps of areas of archaeological interest from physiographical and historical data. The advantage of this theory is that the ignorance is quantified and used to compose the probability maps named as belief, plausibility and belief interval for the archaeological sites. The final digital probability maps show that the Neolithic archaeological sites can be detected in the prefecture of Magnesia. This research study forms a methodological tool for the prediction of new archaeological sites in other areas of archaeological interest according to the physiographical and historical characteristics of the archaeological period being examined. It also contributes to the digital earth modelling and archaeological site protection, one of the most critical and challenging global initiatives. 相似文献

Synthetic Aperture Radar (SAR) remote sensing is increasingly favoured in archaeological applications. However, the effectiveness of this technology for archaeological prospection has so far not been fully assessed. In this study, an integrated single-date and multi-temporal SAR data-processing chain was proposed to sharpen archaeological signs and hence their detection and monitoring. In total, 14 scenes of X-band Cosmo-SkyMed, C-band Sentinel-1 and L-band PALSAR data covering the Western Regions of the Silk Road Corridor in China were employed for two important archaeological sites including the Yumen Frontier Pass with emerging archaeological traces and Niya ruins with subsurface remains. The results pointed out that single-date satellite radar data were useful for the identification of subsurface traces buried under desert in the landscape-scale, whereas for the identification of emerging monuments, Sentinel-1 was limited by its lower spatial resolution compared to TerraSAR and PALSAR data. Multi-date products, such as interferometric coherence, the averaged radar signatures and RGB multi-temporal composites, were effective to sharpen archaeological traces as well as for change detection in Yumen Frontier Pass. This study presents a pilot assessment of satellite SAR data for the analysis and monitoring of archaeological features in the predominantly arid-sandy environmental characteristic of investigated sites. 相似文献
