Modern archaeologists often find it difficult to identify the exact position on the field (and on the maps) of the finds brought to light during archaeological excavations, particularly those conducted before the second half of the 20th century. In these cases, in fact, they are obliged to record data and information on their GIS as being unable to locate the correct place, or even the area, of those ancient archaeological investigations. This inability to be precise creates several problems from a topographical point of view and negatively influences the archaeological reconstruction of specific territories or sites. Therefore, how is it possible to correctly locate and, as a result, mark on the map what was discovered or excavated in the recent past? One possible solution is the 3D reconstruction of a modern landscape through the use of the UAV technology and some derived applications, such as digital techniques based on Structure from Motion and Imaged-Based methodologies. The 3D model can be analyzed using the GIS system, and through the analysis of the micro-relief and aerial photos it is possible to use an important tool to locate past archaeological investigations. In this paper, we present the case study of Mount Siri (Anzi, Basilicata), the location of several important archaeological discoveries which were made during the 19th century.

Examining the region of Basilicata (South Italy) represented in the Atlante Geografico del Regno di Napoli of Giovanni Antonio Rizzi Zannoni we can note the existence of a large number of place names related to a military field (Torre, Guardia, Castello, etc.). Although some of these are related to fortified sites abandoned or no longer exist at the time of the measurements of geographers, and after a first comparison with a census of the sites still active at the end of eighteenth century, we can note a high and uniform distribution of center of defense and observation. In addition to a direct defense in case of attack, the majority of fortified site were also intended to ensure the functioning of a network of sighting and signaling from the coast to the internal zones. What was the average distance between sites? What are those with greater visibility? What was the average time for any visual signals from the coast to inland areas? There were more protected than other centers? The whole site was connected to the main road site? In this paper, we will attempt to answer the question after a first comparison of the place names and the still active site at the time of the atlas and through the use of GIS applications.

[EN] In recent years we have witnessed to a great change in the archaeological and architectural relief due to the introduction of the laser scanner (Böhler 2006; Vosselman and Maas 2010) and to the improvement of the Structure from Motion techniques (Remondino and El-Hakim 2006; Caprioli and Scognamiglio 2009). These new methods allow the restitution of accurate 3D models of small objects, monuments, and territories, for the purpose of study, documentation, divulging, monitoring and restauration (Kourtzellis 2009; De Reu 2013; Hörr and Brunnett 2013; Forte et al. 2015). The data acquisition is made through the use of UAVs (Unmanned Aerial Vehicles) (Colomina and Molina 2014), tools that are becoming ever more economic and efficient. Through the utilization of a drone and by the application of SFM techniques we can realize 3D models in a short time and with reduced costs. This models can be published on the internet or implemented on an APP for tablet or smartphone. Through new technologies we can take advantage of digital content in 3D (Bruno et al. 2010) to observe artifacts, historic buildings and archaeological sites through a different, intriguing and interactive approach, improving communication as well as encouraging real visits of the objects. In the following contribution we first create the 3D models of particular prestigious buildings of the city of Ferrandina (Basilicata, Italy) and after an APP for smartphones and tablets that allows viewing in three dimensions of some monuments, accompanied by a descriptive card and useful information such as opening times, etc. This is a work-in-progress project so the early interesting results presented here are partial., [ES] En los últimos años hemos asistido a un gran cambio en el levantamiento arqueológico y arquitectónico, debido a la introducción del escáner láser (Böhler 2006; Vosselman and Maas 2010) y la mejora de las técnicas de SFM (Remondino and El-Hakim 2006; Caprioli and Scognamiglio 2009). Estos nuevos métodos permiten la restitución de los modelos 3D precisos de pequeños objetos, monumentos y sitios, con el propósito de estudio, documentación, divulgación, vigilancia y restauración (Kourtzellis 2009; De Reu 2013; Hörr and Brunnett 2013; Forte et al. 2015). La adquisición de datos se hizo en su mayoría desde arriba, mediante el uso de UAVs (Unmanned Aerial Vehicles) (Colomina and Molina 2014), es más económica y eficiente. A través de la utilización de un dron y mediante la aplicación de técnicas de SFM podemos tener modelos 3D en un poco tiempo y a coste reducido, los modelos pueden ser publicados en Internet o implementados en una aplicación para tablet o smartphone. A través de las nuevas tecnologías podemos ayudarnos de los contenidos digitales en 3D (Bruno et al. 2010) para observar objetos, edificios históricos, sitios arqueológicos a través de un enfoque diferente, interesante e interactivo, mejorar la comunicación, así como fomentar las visitas reales de objeto. En la siguiente contribución se procedió en primer lugar a la creación del modelo 3D de determinados edificios prestigiosos de la ciudad de Ferrandina (Basilicata, Italia) y después a la creación de una aplicación para teléfonos inteligentes y tabletas que permiten ver en tres dimensiones algunos monumentos, acompañados de un tarjeta descriptiva e información útil, como los horarios de apertura, las direcciones de las rutas, etc. En este artículo presento el trabajo parcial, dejando al descubierto los primeros resultados interesantes.
