The city of Lisbon is the capital of Portugal and has been devastated by catastrophic events in the past, such as earthquakes and tsunamis. This study provides a regional analysis of displacements for the city and its neighbourhoods, between 2008 and 2010, through the application of mutitemporal InSAR techniques on Envisat ASAR images. Smaller areas with identified problems were subjected to a more refined proc...
Accurate and frequent monitoring of dams and its surroundings is an extremely important task to ensure the safety of settlements located downstream. Time-series InSAR techniques are a cost-effective way for measuring millimeter-level displacements on the Earth surface, at a regional scale, and can be used as an early warning system for the safety of structures and their surroundings. This study presents the app...
A monitorização de estruturas é uma atividade de grande importância para garantir a segurança de pessoas e bens. A geodesia tem um papel determinante nesta tarefa ao possibilitar a medição de deslocamentos em zonas de interesse com elevada precisão. A interferometria por radar de abertura sintética (InSAR) permite obter deslocamentos numa rede de observação que contempla não só a estrutura, mas também a sua env...
