Improving Satellite Quickbird-based Identification of Landscape Archaeological Features through Tasseled Cap Transformation and Pca

In this paper, the Tasseled Cap Transformation (TCT) was applied to QuickBird multispectral images for extracting archaeological features linked to ancient human transformations of the landscape. The investigation was performed on Metaponto, one of the most important archaeological sites in the South of Italy. The analysis was focused on the identification of ancient land divisions likely related to Greek colonization. The obtained results showed that the use of TCT and PCA successfully enhanced the spectral information content of satellite QuickBird data; thus, allowing the detection of archaeological features with a high level of detail * Corresponding author.
