| description | The aim of this paper is to analyse, using GIS and remote sensing techniques, the land use/cover change of the city of Dej, in order to explore the spatial and temporal characteristics and the consequences of urbanization trends of the past 250 years. We used a wide range of data, including historical maps and Landsat images from 1984 to 2017. In order to identify the land-use change, we used supervised classification and change detection methods. Analysing the obtained data, we could conclude the fact that, between 1763 and 1990, the area was characterized by a significant urban sprawl and land-use change, due to the economic development and political views (the urban border area increased from 1.2 km2 to 13.72 km2), but after 1990, the suburbanization process has begun, due to the economic failure, having a 13.85% built-up area increase towards S-SE and N direction, constrained by hydrological and geomorphological factors. |
