The contribution presents the analysis of the works carried out within the Sapienza Archaeological Mission in Gortys of Crete, focused on the urban and topographic reconstruction of the city and its surroundings. Specifically, the results, still not conclusive, of the most recent phase of this research are presented (2024-2025), within the framework of a PRIN 2022 funding. The work involved the systematic acquisition of aerial survey images with the aim of producing an orthorectified cartography of the Gortine area and to process the Digital Elevation Models, in order to implement the GIS system, the core of the PRIN project. The archaeological mission also provided the opportunity to experiment with acquisitions in the field of proximity remote sensing through the use of thermal sensors and the application of vegetative indices elaborated on single electromagnetic bands, in a peculiar climatic context such as that of Gortys. The implementation of all this data in the GIS allowed us to analyze the organization of urban spaces in different sectors of the ancient city. Specifically, data relating to the relationship between the two main macro-phases of the city are presented: the hellenistic planning and the roman adjustments.

The contribution presents the results of a research that involves the use of data acquired by a multispectral camera transported by a UAV and their analysis and interpretation in the context of archaeological diagnostics. The experimentation expected the acquisition of multispectral images and the extraction of all the possible vegetation indexes on the basis of the spectral bands of the specific camera used (Sentera 6X). The tests, carried out in different contexts (Antium, Nersae), analyze the readability of the index data extracted from multispectral images in comparison with the marks visible in the panchromatic images, especially considering cases in which the marks are visible only in processed indices that interpolate the NIR band.
