The main goal of this article is to realize an analysis, both qualitative and quantitative, of the continuous urban area of Onesti city green spaces using GIS techniques and demographical data. In order to fulfill our purpose we mapped all the types of green space, roads, buildings and rivers by using aerial images in TNT Mips 6.9. We proceed by creating an attribute table for green spaces and also for buildings (fields for function, high, number of inhabitants and number of floors), creating a vector with small neighborhood areas (very useful for a detailed analysis), go on using some GIS process like vector-raster conversion, raster properties or functions like buffer zones which allowed us to easily figure it out what is the number of inhabitants that lives further or no than 300 m from municipal park and finish with strong and objectives conclusions.
