Land-use changes associated with urban expansion frequently lead to an increase of hazards, both natural and man-made. The process of urbanization is often associated with land-use and land-cover (LULC) changes, leading to a reduction of the infiltration capacity of newly urbanized soil. The goal of this study is to analyze the influence of urban growth on the flood hazard in the case of Santiago...
This study deals with the very high dynamic urban region of Brasilia located in a semi-arid climate. The capital of Brazil will only celebrate its 50th anniversary in 2010 and has a very special urban layout. Originally, only the plano piloto, the present city of Brasilia, was planned by Oscar Niemayer for several hundred thousand inhabitants. At present, the outskirts of Brasilia have become satellite...
Due to continuous world-wide urbanization, especially in developing and emerging countries, urban environment represents one of the most dynamic landscapes on earth. The role of human settlements is becoming more and more important in land management, and the various structures of urban areas differ tremendously depending on social and historical backgrounds. So, beyond land-use and land-cover information,...
Land-use and land-cover (LULC) and their changes have significant influence on heat balance, especially in the urban area. Therefore climate measurement stations are permanently set-up on different land uses, and additionally mobile climate measurements are carried out every year at the same time and similar climate conditions. The study area is Santiago de Chile, one of the most dynamic and fast...
This study focuses on the way urban dynamic processes challenge existing monitoring approaches and how urban structure types (UST) support an effective urban management. Due to their microstructure and the instability of shape, the differentiation of settlement structures is substantially difficult. Hence, highly sophisticated data such as color infrared (CIR) orthophotos as well as methods of image...
Urban remote sensing predominantly focuses on positive growth patterns. Urban planning mainly concentrates on the investigation of cities as an administrative unit. In this paper the phenomenon of a negative urban growth is investigated within an urban region for two selected areas: one selected test area is the gradient from inner urban districts to peri-urban communes, the other selected area is...
