Three decades of urban growth in the city of Shiraz, Iran: A remote sensing and geographic information systems application

Este estudo teve como objetivo desenvolver uma cartografia atual das áreas aterradas na cidade de Vitória (ES), entre os anos 1970 a 2016, utilizando produtos e técnicas de Sensoriamento Remoto orbital e suborbital integrado com os Sistemas de Informações Geográficas, documentos técnicos e plantas/projetos de aterramentos. A partir da ampliação do conceito de aterros, entrevistas e análises das imagens foi possível identificar, delimitar e detalhar os locais que passaram por processos significativos de depósitos de materiais - hidráulicos, inertes e sanitários - totalizando, no período de 46 anos, 15,74 km² (18,2%) da área territorial atual. Constatou-se que praticamente todos os limites da ilha principal e do continente do município de Vitória foram alterados pelas obras de engenharia de aterros expandindo o sistema de circulação viária, áreas uso residencial e de órgãos públicos, espaços de lazer como parte da região da Enseada do Suá, além dos portos e aeroporto.Palavras–chave: Geotecnologias, Análise Geográfica, Ordenamento Territorial e Ambiental.Abstract This study aimed to develop a cartography of the landfills areas in the city of Vitória, state of Espírito Santo - Brazil, between 1970 and 2016, using products and techniques of Remote Sensing orbital and suborbital integrated with Geographic Information Systems, technical documents and plants / projects of grounding. From the expansion of the concept of landfills, interviews and analysis of the images, it was possible to identify, delimit and detail the locations that went through significant processes of deposits of materials - hydraulic, inert and sanitary - totaling, in the period of 46 years, 15.74 Km² (18.2%) of the current territorial area. It was verified that practically all the limits of the main island and of the mainland of the municipality of Vitória were altered by the engineering works expanding the circulation system, residential and public use areas, leisure spaces as part of the region cove Suá, besides ports and airport.Keywords: Geotechnologies, Geographical Analysis, Territorial Planning.

Study Case

This work analyses soil loss over the last 150 years due to urban growth in one of the boroughs of highest environmental value around Madrid (Spain), i.e. Colmenar Viejo. The extent and patterns followed by urban extension are examined retrospectively using a present cartographic base layer. This evolutionary approach considering space and time has required a thorough compilation of cartographic sources that were created using classic topography, photogrammetry or remote sensing, some of which have been rarely used so far. These documents have been georeferenced, edited and handled using Geographic Information Systems (GIS) and remote sensing programs. Urban growth in Colmenar Viejo has been steady, has registered exponential increases (soil sealing affected 0.14% of the total municipal territory in 1861 and covers 2.64% nowadays) and has followed similar patterns to other Spanish towns influenced by metropolitan processes.
