Monitoring Land –Use Changes by GIS and Remote Sensing Techniques: Case Study of Trabzon

While determining future growing-areas of cities, monitoring city-growth, in other words, determining land-use changes has an important role in urban development. Immigration, especially emerged from improvement of industry, is an important factor causing urban land-use changes. In last 15-20 years period, collapse of Soviet Union and opening Sarp customs have contributed to considerable income for the Black Sea regional economy in Turkey. The city Trabzon which is the centre of the Black Sea region has been mostly affected from this economical development. Emerging of shore-trade and consequently, improving commercial activities and activating regional tourism caused to immigration from surrounding cities to Trabzon. In addition to this, increasing population density due to local population-growth caused to changes in urban land-use. In this study, in order to determine Trabzon’s land-use changes in the last 40 years, required data was acquired for 31 square kilometer area, processed, analyzed and some queries were executed. In this respect, Standard Topographic Maps, produced in 1960, and in scale of 1/25.000, were digitized and required vector data was overlaid on it. Besides, four aerial photographs- 1974, Landsat 5 TM image- 1986 and Landsat 7 TM+ image- 2000 were provided. This data processed using GIS and Remot
