Towards Archaeologically Relevant Hyperspectral Sampling
To date, the archaeological potential of airborne imaging spectroscopy is quite limited due to the generally insufficient Ground-Sampling Distance (GSD) during data acquisition. Although the common GSD of about 2-3 m might be sufficient for ecological or hydrological studies, airborne hyperspectral data useful for archaeological studies should have a limit of spatial resolution of at least 50 centimeters or less. The acquisition and technical processing of such data for archaeological aims is one of the key research lines of the recently found LBI for Archaeological Prospection and Remote Sensing (Vienna). After a short introduction onto this newly established LBI and its aims concerning archaeological airborne hyperspectral scanning, this presentation wants to focus on some hyperspectral data sets that were flown with specific archaeological use in mind. Because they are characterised by a GSD of less than 50 cm, the spatial resolution of these data starts to become comparable with the results gained by digital airphoto coverage. Some real-world examples will highlight the information that can be extracted from such datasets, while some hints for future improvements will conclude this presentation.
