Paper Abstract

In this article, a combined application of a segmentation method with a texturing procedure is employed for delimitation of urban areas in a temporal series of Landsat satellite images over the Sintra-Cascais municipalities. The study area is particularly sensitive as it contains the Natural Park of Sintra-Cascais (PNSC) which is subject to intensive anthropogenic pressure. Selected spatial metrics are used for analysing the evolution of urban pattern for the whole study area and also inside and outside the PNSC. Results reveal that built areas have increased almost 30% and that the pattern of urban growth is being made differently inside and outside the natural park between years 1989 and 2001.
