Changes in land use / land cover are the result of interaction between natural processes and human activity. Using GIS analysis to estimate the dynamic of these changes we can detect former trends and their simulation in the future. Diagnosed directions of changes can be used e.g. to create local plans of spatial management or region growth policy. Main goal of this study was to diagnose main trends of changes in land use / land cover in Malopolska voivodeship in last 25 years (1986-2010). Results were shown as statistics and map compositions. Project was created based on RapidEye and LANDSAT 5 TM satellite data and aerial imagery from 2009-2010. The best way to process huge amount and various data was to use Object Based Image Analysis (OBIA). As the results of classification we received 10 classes of land use for both terms of analyses (1986-1987 and 2009-2010). Identified classes were: bare soil, grass-covered areas, urban areas, rivers and watercourses, coniferous forest, leaf forest, peatbog, and other areas. Results show, that especially 2 classes arisen much: forest (4.39%) and urban areas (2.40%), mostly at the expanse of agricultural (-3.60%) and grass-covered areas (-1.18%). Based on results we can say, that changes detected in past 25 years in Małopolska region, which we can also notice today, agree with general trends of landscape changes, that we can observe in Poland for the last 3 decades. These general changes are: renewed succession of forest on areas where agricultural production discontinued; also intense development of road infrastructure. Object Based Image Analysis allowed to realize these study for area of more than 15 000 km2for only a few weeks.
