Archaeological usability of Hyperspectral images: successes and failures of image processing techniques

In the last decade, particular interest in the use of airborne hyperspectral systems as support in archaeological research has taken place in Italy, where the MIVIS sensor has found large application. The different projects involving its use have tried to demonstrate that MIVIS imagery represents an important complementary source of information for archaeological goals. However, in most of the cases, the limits and the problems generated by using hyperspectral images have never been stressed enough in the research reports, while the spotlight has been focused only on the positive outcomes.
