A Window for the Hidden Past: Revealing Architectural Remains Based on Field Spectroscopy Data Analysis

Field spectroscopy is the quantitative measurement of the radiance, irradiance, reflectance, or transmission in the field. It is principally used to understand the interaction of different materials based on electromagnetic radiation. Although field spectroscopy has been systematically exploited for the calibration of remote sensing sensors, nowadays spectroscopy is being used for a variety of remote sensing applications. This chapter aims to provide an overview of the potential use of field spectroscopy for supporting archaeological research. The overview is based on examples and applications from different archaeological environments in the eastern Mediterranean basin, specifically targeted for the detection of underground architectural remains. As is demonstrated in this chapter, field spectroscopy uses hyperspectral signatures to validate or calibrate the space-borne or airborne images, while at the same time spectroscopy may assist in better understanding of the interaction of the electromagnetic radiation with the different targets and therefore in developing new algorithms to support future archaeological applications.
