Use and processing of multispectral images in proximity remote sensing

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.
