“…The sloping part of the tell seems to behave differently due to rainfall erosion processes. All these results denote the correlation between the morphology and the spectral response of canopy on the magoules (Agapiou et al, 2012a). Moreover ground spectral signatures at Palaepaphos area (Fig.…”

“…These tells, also known as magoules, are typically low hills, which arise approximately 5-10 m above the surrounding area. Hundreds of such tells are distributed in the Thessalian plains, which are cultivated systematically with crops [3,9]. Some photos from such magoules are shown in Figure 7.…”

Several studies in the past have examined the spectral capability of multispectral and hyperspectral imagery for the identification of crop marks, while recent studies have applied different vegetation indices in order to support remote sensing archaeological applications. However, the use of vegetation indices for the detection of crop marks lacks in accuracy assessment and critical evaluation. In this study, 71 vegetation indices were indexed, from the relevant bibliography, and evaluated for their potential to detect such crop marks. During this study, several ground spectroradiometric campaigns took place, in a controlled archaeological environment in Cyprus, cultivated with barley crops, during a complete phenological cycle (2011)(2012). All vegetation indices, both broadband and narrowband, were evaluated for their separability performance, and the results were presented through tables and diagrams. In the end, the use of more than one vegetation index is suggested in order to enhance the final results. In fact, several not widely used vegetation indices are suggested and evaluated using both Landsat TM and EO-1 Hyperion images.

“…A very promising aspect of remote sensing technology is the fact that it can be applied to identify human traces and buried archaeological remains. This task is mainly carried out using grayscale archive aerial and satellite images (Riley 1987), ground spectroradiometric hyperspectral data (Agapiou et al, 2012a;2011a) and image interpretation of crop marks (Alexakis et al 2011;Cavalli et al, 2007). The latest is a well-established procedure in archaeological research.…”

Commission VI, WG VI/4 KEY WORDS: remote sensing archaeology, UAV, ground spectroscopy, crop marks, cultural heritage ABSTRACT:Remote sensing has open up new dimensions in archaeological research. Although there has been significant progress in increasing the resolution of space/aerial sensors and image processing, the detection of the crop (and soil marks) formations, which relate to buried archaeological remains, are difficult to detect since these marks may not be visible in the images if observed over different period or at different spatial/spectral resolution. In order to support the improvement of earth observation remote sensing technologies specifically targeting archaeological research, a better understanding of the crop/soil marks formation needs to be studied in detail. In this paper the contribution of both Unmanned Aerial Systems as well ground spectroradiometers is discussed in a variety of examples applied in the eastern Mediterranean region (Cyprus and Greece) as well in Central Europe (Hungary). In-situ spectroradiometric campaigns can be applied for the removal of atmospheric impact to simultaneous satellite overpass images. In addition, as shown in this paper, the systematic collection of ground truth data prior to the satellite/aerial acquisition can be used to detect the optimum temporal and spectral resolution for the detection of stress vegetation related to buried archaeological remains. Moreover, phenological studies of the crops from the area of interest can be simulated to the potential sensors based on their Relative Response Filters and therefore prepare better the satellite-aerial campaigns. Ground data and the use of Unmanned Aerial Systems (UAS) can provide an increased insight for studying the formation of crop and soil marks. New algorithms such as vegetation indices and linear orthogonal equations for the enhancement of crop marks can be developed based on the specific spectral characteristics of the area. As well, UAS can be used for remote sensing applications in order to document, survey and model cultural heritage and archaeological sites.
