Starting with late 2018, a new archaeological research project has been unfolding in the framework funded by the Romanian Governmental Unit for Research and Development (UEFISCDI) dedicated to top fundamental research, as one of the few winners of 2016 edition (the single to date) of ‘Complex Projects for Frontier Research’ competition. The Project, whose aims and methods will be shortly presented further, is entitled ‘Hidden Landscapes: Exploratory Remote-sensing for the Archaeology of the Lost Roads, Borders and Battlefields of South-Eastern Carpathians’ (HiLands). It implements a systematic and diachronic investigation of the historic strategic circulation corridors crossing the South-Eastern part of the Carpathian Mountains – the main gate used along ages by people transiting between Transylvania and the Danube or the Black Sea. In order to achieve such aims we have been exploring, starting from large scale LiDAR surveys, the circulation corridors’ diachronic archaeological fingerprint, preserved in the shape of repeatedly fortified landscapes. LiDAR surveys have been carried on continuously since 2018, by airplane, but also with portable sensors based on SLAM technology. The results of the LiDAR explorations were enhanced by field surveys, geophysical prospections and pin-pointed excavations, in order to elucidate the nature of anomalies or better contextualize the significance and layout of the roads’ routes. The results of these activities are resumed in a constantly updated, open access, online data base of archaeological sites - The archaeological index of South-Eastern Carpathians (AISEC). The current contribution details the essentials of HiLands research (aims, concepts, methods), in order to introduce in the scientific circuit the AISEC’s functions and instruments, ready to be used as citable work.
