The introduction of new technologies in recent decades has opened new methodological avenues and theoretical approaches that are of great interest to archaeological research and conservation of historical heritage. This study delves into two of these, Structure from Motion photogrammetry by drone and LiDAR, and describes their advantages and disadvantages in the framework of Architecture and Landscape analyses. Case studies of each type were carried out on two medieval fortresses, Órgiva and Poqueira (and their surroundings) perched on steep slopes of Sierra Nevada (Granada, Spain). Each of the studies took into account questions of graphic quality, geometric precision, coverage and handling costs and offer a method allowing integration of the microspatial scale of Archaeology of Architecture into the macrospatial scale of Landscape Archaeology. These new remote sensing technologies are of great use in obtaining quality and precise records that enable offering new data and perspectives to old historical and archaeological problems.
