Three-dimensional models are required to virtualize heritage sites. In recent years, different techniques that ease their generation have been consolidated, such as photogrammetry with Unmanned Aerial Vehicles (UAVs). Nonmetric cameras allow relatively inexpensive data collections. Traditional aerial photogrammetry has established methodologies, but there are not commonly used recommendations for the selection of parameters when working with UAV platforms. This research applies the Taguchi Design of Experiments Method, with four parameters (height of flight, forward and lateral overlaps, and inclination angle of the sensor) and three levels (L9 matrix and nine flights), to determine the set that offers the best metric goodness and, therefore, the most faithful model. The Roman civitas of Juliobriga (Cantabria, North of Spain) was selected for this experiment. The optimal flight results of the average signal-to-noise ratio analysis were height of 15 m, forward and lateral overlaps of 80%, and inclination of 0° (nadiral). This research also highlights the noticeable contribution of the inclination in the accuracy of the model with respect to the others, which is 16.4 times higher than that of the less relevant one (height of flight). This leads to propose avoiding inclination angle as a variable, and the sole development of nadiral flights to obtain accurate models.

RESUMENLos trabajos de prospección y de fotointerpretación han permitido localizar un nuevo yacimiento en el entorno de Sasamón, que pudo estar relacionado con la fundación de la ciudad y perduró en el tiempo como indica la presencia de terra sigillata hispánica altoimperial y terra sigillata hispánica tardía. El yacimiento representa un elemento novedoso dentro del proceso de ocupación del espacio en la región, según una estrategia claramente romana. En este trabajo, además de aspectos metodológicos, se aborda el estudio de los materiales, planteando algunas hipótesis sobre su finalidad y cronología. SUMMARYPedological surveys and oblique aerial image interpretation have led us to the location of a new site in the suburban area of Sasamón. Its original function may have been related with to the foundation of the city of Segisamo and afterwards lasted throughout several centuries according to the presence of Late Hispanic sigillata. The site represents new findings on the Roman settlement pattern in the area. In addition to methodological issues, this paper addresses the study of the material culture in order to propose hypothesis about function and chronology.PALABRAS CLAVES: prospección intra-site, fotografía aérea, cerámica romana, asentamiento rural, Hispania Citerior.
