“…8.15). The authors have conducted previous research in this area to create a common geo-database of all monuments, estimating hazards, and produce risk maps from remote sensing data (Agapiou et al, 2013). These monuments were clustered into five groups that shared similar geomorphological characteristics.…”

This chapter presents examples of remote sensing studies for monitoring natural hazards related to ancient monuments and archaeological sites in Cyprus. Through these studies, the use of Earth Observation, and specifically the contribution of the European Copernicus Programme, is highlighted. Most of them have been carried out during the last years, within the framework of funded research projects. The various case studies presented in this chapter underscore Earth Observation's mingling with other remote sensing techniques (both middle range and terrestrial) and geoinformatics towards inclusive monitoring of cultural heritage and prevention against possible hazards.The chapter unfolds in two parts: The first part introduces an overview of the potential contribution of Earth Observation to the Cultural Heritage Disaster Risk Management (DRM) cycle, with specific focus on the Eastern Mediterranean basin. The DRM includes six consecutive steps that require various inputs, including the context, threats and monitoring phases. For each step, the role of Earth Observation sensors and their related products are discussed.The second part of this chapter focuses on studies dealing with natural hazards in Cyprus using optical and radar datasets. These studies include the following: (a) soil erosion by water, (b) vegetation growth, and (c) detection of surface displacements, in sites with archaeological interest.The chapter ends with a comprehensive risk assessment report of various hazards (both natural and anthropogenic) using the Analytical Hierarchy Process (AHP) method. This assessment concerns the western part of Cyprus, namely the Paphos District, where more than 200 monuments are found.

“…Low resolution space data like the Moderate Resolution Imaging Spectroradiometer (MODIS) Terra and Aqua platforms and Defense Meteorological Satellite Program (DMSP) -Operational Linescan System (OLS), medium resolution images from Landsat and ASTER sensors, as well as high resolution data from QuickBird have been processed separately. Results from the analysis of the low-resolution MODIS Terra and Aqua products regarding the Aerosol Optical Thickness (AOT) over the area of interest for the entire year of 2012 have shown the AOT fluctuations over the seasons [5]. AOT is linked to the air pollution, and therefore insights regarding the impact of the pollutants to the standing monuments can be investigated.…”

The scope of this work is to present an integrated methodological multi-scale and multi-temporal approach for the study of ancient monuments in their environmental context. The presented work showcases the interdisciplinary research experience gained during the last years by the Remote Sensing and Geo-Environment Lab (ERATOSTHENES Research Centre) of the Cyprus University of Technology. The developed capabilities of the Eratosthenes Research Centre derived from the successful implementation of various national and European research projects within the wider area of architectural heritage study and protection. In this framework geospatial tools, earth observation and in situ monitoring and measurements were merged and further investigated. The case study concerns Paphos town in Cyprus and particularly the archaeological site of Nea Paphos and the Hellenistic necropolis "Tombs of the Kings", a UNESCO World Heritage Site.The study encompasses a variety of technological tools to approach the area of interest, moving from a landscape level (macroscale) to isolated monument scale (micro-scale). For the macro-scale approach novel earth observation and aerial image (semi-macro scale) processing techniques have been employed, while in a micro-scale level the study extents from the geometric documentation of the tombs to the image processing mapping surface weathering features, as well as seismic performance of single monuments. The overall results demonstrate that such geospatial data linked to the individual characteristics of each monument can assist towards the implementation of various directives and conventions, while offering an integrate understanding of the monuments state of preservation, not seen as an isolated unit, but as part of its natural and anthropogenic environment, inevitably affecting its viability in time and place.

Map indicating anthropogenic and natural hazards over Paphos District as follow: (a) Landsides map: very high hazard and high hazard areas are indicated with red; (b) Erosion map: areas where the soil loss is greater than the mean value soil loss of the whole district are indicated with red ; (c) Salinity map: areas closesly to the sea are indicated with red; (d) Tectonic activity: high and very high hazard area are indicated with red; (e) Urban expansion; (f) Road network proximity (250 m); (g) Drainage network (50 meter buffer zone) and (h) Fires map observed during the period 2010-2013 (see more details in [4]).The overall results, generated hazard maps for each type of threat which was then grouped together following the AHP methodology [4]. These results were then further improved [6], based on the clustering of the monuments prior to the AHP evaluation. The various archaeological sites under investigation (including those mentioned in this paper) have been grouped into five main categories based on thei...
