This paper analyses the research carried out in the Tiwanaku World Heritage site in Bolivia, using unmanned aerial vehicles and satellite images. The combined use of images with different scales has made it possible to locate many archaeological structures unknown to date (drainage systems, walls, circular crop marks, and a possible dock). The Sentinel‐2 images, which were processed using principal components analysis and histogram equalization, show the river beds, flood‐prone areas, and several buried drainage channels surrounding the most important structures. The archaeological evidence obtained with the digital terrain model and natural color/multispectral images enables us to contrast a new dimension of land and water uses that go beyond what was known to date. In the same way, these images enable us to understand in detail the environmental characteristics, land use, building distribution, and flood defense structures of the Tiwanaku culture throughout its history, within the context of the environmental conditions of the Bolivian altiplano. This study allowed the authors to collect new information and pose questions on the relationship of this site with water, as well as a better understanding of the extent and habitat of this historical population.

使用遥感（无人机和卫星图像）对蒂瓦纳库世界遗产（玻利维亚）采取新的环境和空间方法

本文利用无人飞行器和卫星图像分析了在玻利维亚的蒂瓦纳库世界遗产中进行的研究。结合使用不同比例的图像可以找到许多迄今未知的考古结构（排水系统，墙壁，圆形作物标记和可能的码头）。使用主成分分析和直方图均衡处理的Sentinel-2图像显示了河床，易发洪水区域以及围绕最重要结构的数个地下排水渠。利用数字地形模型和自然色彩/多光谱图像获得的考古证据使我们能够对比土地和水利用的新领域，而这一领域已经超越了迄今为止已知的范围。用同样的方式 这些图像使我们能够在玻利维亚高原环境条件的背景下详细了解Tiwanaku文化在整个历史中的环境特征，土地利用，建筑物分布和防洪结构。这项研究使作者能够收集有关该地点与水之间的关系的新信息并提出问题，并更好地了解这一历史人口的范围和栖息地。
