The megalithic sites from southwest Iberia represent one of the largest clusters of prehistoric monuments in Europe from the Neolithic and Copper Age (fifth and third millennia cal bc). Unlike other regions from western Europe, there has not been a recent effort to map the distribution of these kinds of burials across this vast territory. Therefore, this article aims to collect geographic information from three regions of southwest Iberia (Alentejo and Beira Baixa from Portugal and Extremadura from Spain) and to compare the archaeological evidence between different landscape units. We have mapped already known megaliths (ca 2000) and settlements (ca 1500) in this area. Moreover, through the interpretation of light detection and ranging (LiDAR) datasets, we have identified new walled enclosures and megaliths in the Extremadura region (Spain), the only one of the three where LiDAR data are available. The new data reveals new connections between settlements, burials and other archaeological evidence. Finally, we discuss the impact that these new data have on a new overall interpretation of megalithic landscapes from the Iberian Peninsula, stressing also the potential risks that the massive application of remote sensing can have in the production of archaeological knowledge.

数着无形的记录？LiDAR在解释伊比利亚西南部巨石景观（埃斯特雷马杜拉，阿连特茹和贝拉拜萨）中的作用

从西南伊比利亚巨石阵遗址代表了从新石器时代和铜器时代（第五和第三千年CAL在欧洲的史前遗址最大的星团之一BC）。与西欧其他地区不同，最近没有做出任何努力来绘制此类vast葬在整个广阔领土上的分布图。因此，本文旨在收集伊比利亚西南部三个地区的地理信息（葡萄牙的Alentejo和Beira Baixa以及西班牙的埃斯特雷马杜拉），并比较不同景观单元之间的考古证据。我们已经绘制了已知的巨石（大约2000年）和定居点（大约1500）。此外，通过对光检测和测距（LiDAR）数据集的解释，我们在埃斯特雷马杜拉地区（西班牙）中确定了新的围墙围护结构和巨石，这是可获得的三个LiDAR数据中的唯一一个。新数据揭示了定居点，墓葬和其他考古证据之间的新联系。最后，我们讨论了这些新数据对伊比利亚半岛巨石景观的新整体解释的影响，同时强调了遥感技术在考古知识生产中的大量应用可能带来的潜在风险。
