![]() The application of the presented methodology in the island of Lemnos in the North Aegean Sea (Greece) indicated that 9.3% of the study region is suitable for landfill siting with grading values greater than 9. The last step is a spatial clustering process, which is being performed in order to reveal the most suitable areas, allowing an initial ranking and selection of candidate landfill sites. ![]() The resulting land suitability is reported on a grading scale of 0-10, which is, respectively, from least to most suitable areas. With the aid of the simple additive weighting method, the suitability for landfill siting of the study region is finally evaluated. The relative importance weights of the evaluation criteria are estimated using the analytic hierarchy process. Then the methodology utilizes spatial analysis processes to create the evaluation criteria, which are mainly based on Greek and EU legislation, but are also based on international practice and practical guidelines. The initial step is the formation of the multiple criteria problem's hierarchical structure. The final goal of the methodology is to evaluate the suitability of the study region in order to optimally site a landfill. Some of the most modern sporting venues in the world were built to host the 2004 Olympic Games.The present work describes a spatial methodology which comprises several methods from different scientific fields such as multiple criteria analysis, geographic information systems, spatial analysis and spatial statistics. When the International Olympic Committee expressed its concern over the progress of construction work of the new Olympic venues, a new Organizing Committee was formed and Athens was transformed into a city that uses state-of-the-art technology in transportation and urban development. The second Landsat 5 image was acquired on 07 July 2004 - Athens hosted the Games of the XXVIII Olympiad, commonly known as the 2004 Summer Olympics. In preparation for the 2004 Olympic Games the city refreshed its image with the introduction of state-of-the-art transport means, a new airport, pedestrianised areas, new museums and public squares. Throughout the 1990s a series of measures were taken successfully to combat pollution. Our first Landsat 5 image was acquired on 03 July 1984 - Greece entered into the European Union in 1981 and this brought new investment, along with problems of congestion and air pollution. The geomorphology of the area – a plain surrounded by mountain ranges and facing the sea - frequently causes temperature inversion phenomena, which partly enhance the city’s air pollution. 1980 and suffered from overcrowding, traffic congestion and air pollution it is one of the most polluted cities in Europe. Athens has grown very rapidly in the years after the war until ca. With its suburbs, Athens has a population of about 3.7 million people, representing more than a third of the total population of Greece. The newer parts of the city are mostly constructed from grey concrete and suffer from a lack of parks and amenities. Most of the older and wealthier parts of the city cluster around this area, which is also where most of the tourist attractions and museums are. The centre of the modern city is at Syntagma Square (Constitution Square), site of the former Royal Palace, the Greek Parliament and other 19th century public buildings. ![]() Since Athens has expanded to cover the entire plain, up to its natural boundaries, it is unlikely that the city will grow significantly in area in the future. The city port of Pireas (ancient name Piraeus) was separated from the city in ancient times but has now been absorbed into greater Athens. The ancient site of the city is centred on the rocky hill of the Acropolis. The land is rocky and of marginal fertility. It is named after its patron goddess, Athena.Īthens sprawls across the central plain of Attica, which is bound by mount Aegaleo to the west, mount Parnitha to the north, mount Penteli to the northeast, mount Hymettus to the east, and the Saronic Gulf to the south-west. A cosmopolitan modern city, Athens is famous for being a powerful city-state and a very important centre of learning in ancient times. Twenty years separate these two Landsat thematic mapper images of Athens, the capital of Greece.Īthens is also the capital of the Attica region.
