Hyperspectral data recorded from satellite platforms are often ill-suited for
geo-archaeological prospection due to low spatial resolution. The established
potential of hyperspectral data from airborne sensors in identifying
archaeological features has, on the other side, generated increased interest in
enhancing hyperspectral data to achieve higher spatial resolution. This
improvement is crucial for detecting traces linked to sub-surface
geo-archaeological features and can make satellite hyperspectral acquisitions
more suitable for archaeological research. This research assesses the usability
of pansharpened PRISMA satellite products in geo-archaeological prospections.
Three pan-sharpening methods (GSA, MTF-GLP and HySure) are compared
quantitatively and qualitatively and tested over the archaeological landscape
of Aquileia (Italy). The results suggest that the application of pansharpening
techniques makes hyperspectral satellite imagery highly suitable, under certain
conditions, to the identification of sub-surface archaeological features of
small and large size.

该研究评估了 PRISMA 卫星产品在地质考古勘探中的可用性，对比了三种泛锐化方法并测试了在意大利 Aquileia 考古景观上的效果，结果表明在特定条件下，泛锐化技术使高光谱卫星图像非常适用于识别不同大小的地下考古遗迹。
