Monitoring the urban expansion of Thrakomakedones area (Northwestern Athens) due to the Olympic Games using high resolution satellite data and GIS techniques

摘要

The area of study is the broader area of North Western Athens near to Thrakomakedones village. Due to the 2004 Olympic Games a lot of changes occurred in that area. The aim of this study was to detect and map these changes, estimate the urban expansion rate and the human interferences in the natural landscape, using remote sensing data and GIS techniques. Airphotos and high resolution satellite data covering the period 2000-2007 and topographic maps of 1:5.000 scale were used for the urban growth mapping. Finally the qualitative and quantitative results of this study are presented in this paper.
