The Etruscan site of Pyrgi extended over 10 ha along the Tyrrhenian coastline. Fieldwork has so far brought to light the sanctuary and a ceremonial complex at the southern edge of the settlement, whereas additional evidence is provided by a section cut by sea erosion across the site. The archaeological layer is about 2 m thick and includes dry masonry buildings arranged into lots; the most superficial features are disturbed by deep agricultural activities and the top layer includes scattered building material (limestone and tuff blocks). At this site, the efficacy of geophysical prospections are generally affected by the nearby presence of the beach's magnetic sand and the railway line. The use of dense ground penetrating radar (GPR) data proved to be the most suitable method in the mapping of buried archeological structures and made it possible to map out the topographic layout of the area which is currently under excavation. The dense three‐dimensional georadar (GPR) data highlight the presence of structures implanted at different topographic levels and provide preliminary information about the main building interventions and planimetric modifications inside the urban lots. The work was extremely useful for the future planning of the archaeological excavation as it makes it possible to reduce the costs and environmental impact of the archaeological activity. The georadar anomalies were confirmed by an archaeological test‐trench conducted in the surveyed area.

皮尔吉(Santa Severa,罗马)考古遗址的大规模重建的密集地雷达测量

皮尔吉(Pyrgi)的伊特鲁里亚(Etruscan)遗址沿第勒尼安(Tyrrhenian)海岸线延伸了超过10公顷。迄今为止,实地考察已经揭示了该定居点南部边缘的圣所和礼仪建筑群,而通过整个场地被海蚀所切割的剖面提供了更多的证据。考古层厚约2 m​​,包括成批布置的干燥砖石建筑。最深层的特征受到深耕的农业活动的干扰,顶层包括分散的建筑材料(石灰石和凝灰岩砌块)。在这个地点,地球物理勘探的功效通常会受到附近海滩磁沙和铁路线影响的影响。事实证明,使用密集的探地雷达(GPR)数据是埋藏考古结构图绘制中最合适的方法,并且可以绘制出当前正在挖掘的区域的地形布局。密集的三维地质雷达(GPR)数据突出显示了在不同地形级别上植入的结构的存在,并提供了有关城市地段内主要建筑干预措施和平面修改的初步信息。这项工作对于考古发掘的未来规划极为有用,因为它可以降低考古活动的成本和环境影响。在被调查地区进行的考古试验证实了雷达雷达异常。
