Abstract

The rapid growth of urban areas and the increase in sealed surfaces have significant implications for environmental management and urban planning. Monitoring and quantifying sealed surfaces are crucial for understanding urbanization processes and their impacts. This article deals with the issues of mapping the dimension of soil sealing in Craiova city, during the last two decades using GIS and remote sensing techniques. As the Normalized Difference Builtup Index (NDBI) has emerged as a valuable tool for assessing sealed surfaces and evaluating urban expansion, it was selected as preferred method selected to determine the dimension of soil sealing.

Comparative case study regarding the urban evolution form of three european capital cities using GIS

Adelina NENIU Cristiana VÎLCEA
Abstract

Urban settlements have always been attractive for the population throughout the history for a better living purposes, working opportunities or even good places for robbery during the wars or migrations. Depending on natural conditions, history or migratory events, cities around the world had known a spectacular evolution over the time, knowing different stages of organized or chaotic growth of their form. Regardless of the population increase registered in the past or the present demographic decline which affects most of the European states, the main cities continued to extend their area. This research presents, in a comparative study, the evolution of three European capitals (Bucharest, Paris and Madrid) in different moments of the history, starting with the 15th century. The study also includes an analysis of the demographic evolution. Using old cartographic resources, recent satellite images and open access databases, the authors analyse the evolution of the form and main directions of urban extension of the three European capitals in relation to the natural conditions and main roads. All data and cartographic resources had been processed and represented using open-source GIS software.
