DESCRIPTION:Over the last decades\, remote sensing techniques have contribu
 ted to supporting cultural\nheritage studies and management\, including ar
 chaeological sites as well as their territorial context and\ngeographical 
 surroundings. This paper aims to investigate the capabilities and limitati
 ons of the new\nhyperspectral sensor PRISMA (Precursore IperSpettrale dell
 a Missione Applicativa) by the Italian\nSpace Agency (ASI)\, still little 
 applied to archaeological studies. The PRISMA sensor was tested on\nItalia
 n terrestrial (Alba Fucens\, Massa D’Albe\, L’Aquila) and marine (Sinu
 essa\, Mondragone\, Caserta)\narchaeological sites. A comparison between P
 RISMA hyperspectral imagery and the well-known\nSentinel-2 Multi-Spectral 
 Instrument (MSI) was performed in order to better understand features and\
 noutputs useful to investigate the aforementioned areas. At first\, bad ba
 nds analysis and noise removal\nwere performed\, in order to delete the nu
 merically corrupted bands. Principal component analysis\n(PCA) was carried
  out to highlight invisible details in the original image\; then\, spectra
 l signatures of\nrepresentative areas were extracted and compared to Senti
 nel-2 data. At last\, a classification analysis\n(ML and SAM) was performe
 d both on PRISMA and Sentinel-2 imagery. The results showed a full\nagreem
 ent between Sentinel and PRISMA data\, enhancing the capability of PRISMA 
 in extrapolating\nmore spectral information and providing a better reliabi
 lity in the extraction of the features.\nthese first analyses\, applied in
  landscape archaeology studies\, highlight\nthe great spectral operational
  capabilities of the PRISMA sensor. In future studies\, a great\nadvantage
  can be brought by performing a reliable pansharpening in order to increas
 e\nthe resolution of the final images (geometric resolution from pancromat
 hic and spectral\nresolution from hyperspectral data)\, as well as a more 
 stable multitemporal acquisition in\nthe areas under investigation.
