“…En este contexto en concreto, el infrarrojo cercano aporta información sobre el estado morfológico y fisiológico del cultivo más allá de los límites perceptibles por el ojo humano. Para este estudio analizamos la banda del infrarrojo cercano NIR de 850 nm, así como los resultados de un cálculo del NVDI (Normalized Difference Vegetation Index) y el índice PSRI (Plant Senescence Reflectance Index), que ya habían deparado interesantes resultados en la investigación del castro vetón de Villasviejas de Tamuja (SALGADO CARMONA et al, 2020).…”

En el marco del proyecto que analiza los paisajes arqueológicos en la transición entre la Edad del Hierro y época romana en la comarca del Odra-Pisuerga hemos prestado especial atención al estudio de la antigua ciudad romana de Segisamo (Sasamón). Desde 2019, a partir de una primera cobertura aérea, hemos sido capaces de reconocer en el sector noroeste de la ciudad la presencia de estructuras arqueológicas que han sido objeto de sucesivas prospecciones aéreas usando UAVs (RGB y NIR) y geofísicas. Esta aproximación no destructiva ha permitido recuperar un sector desconocido de la ciudad romana de Segisamo y plantear nuevas hipótesis acerca de los límites de la ciudad.

“…False-color multichannel composites were produced either by using the MS datasets for image-based modeling directly or by combining overlapping orthoimages of different wavelengths. Most MS composites where either reduced through PCA [50,84,109] or processed for normalized difference vegetation index (NDVI) mapping [50,52,54,56,57,60,[66][67][68][70][71][72]75,76,[84][85][86]97,99,104,109], in order to enhance the contrast between the proxies of buried remains and the landscape matrix. It is worth mentioning that a few studies [50,60,75,86,97,99] reported the use of multiple radiometric vegetation and soil indices to identify which wavelength combinations maximized the local contrasts.…”

Another notable finding was that all thermal investigations were purposed towards archaeological prospection activities.…”

Over the last decade, we have witnessed momentous technological developments in unmanned aircraft systems (UAS) and in lightweight sensors operating at various wavelengths, at and beyond the visible spectrum, which can be integrated with unmanned aerial platforms. These innovations have made feasible close-range and high-resolution remote sensing for numerous archaeological applications, including documentation, prospection, and monitoring bridging the gap between satellite, high-altitude airborne, and terrestrial sensing of historical sites and landscapes. In this article, we track the progress made so far, by systematically reviewing the literature relevant to the combined use of UAS platforms with visible, infrared, multi-spectral, hyper-spectral, laser, and radar sensors to reveal archaeological features otherwise invisible to archaeologists with applied non-destructive techniques. We review, specific applications and their global distribution, as well as commonly used platforms, sensors, and data-processing workflows. Furthermore, we identify the contemporary state-of-the-art and discuss the challenges that have already been overcome, and those that have not, to propose suggestions for future research.
