The application of field imaging spectrometer system(FISS) in archeology of ancient copper smelting site

Abstract

During the archaeological study of culture layers, much attention is paid to the filler of the materials. The fired soil (iron oxide) and carbonized substance are the primary targets of interest which are related to the culture layers. FISS is the first field imaging spectrometer based on a cooling area CCD developed in China. The number of bands of this instrument is 344, spectral range 379–870nm, and spectral resolution 4–7nm. The aim of this paper is to test how to use the imaging spectrometer data to help the discrimination of culture layers in ancient copper melting site since hyperspectral remote sensing provides new perspectives for the study of soils. In the application of FISS in the archeology of ancient copper smelting site, both supervised and unsupervised unmixing and classification techniques can be useful for detecting soil component.
