At: IEEE ARGENCON ; San Miguel de Tucuman ; 6.6.2018 - 8.6.2018 ; This work describes the basic guidelines in order to study landslides using remote sensing. There are presented three test cases in different scenarios: The first one in South Tyrol (Northern Italy), the second one in El Hierro Island (Canary Islands, Spain), and the last one in Sierras Chicas (Córdoba, Argentina). Implemented techniques were: a) Photointerpretation, b) Interferometry between pairs to generate displacement maps and c) Multitemporal interferometry (Persistent Scatterer – PS) to analyze displacements in temporal series of SAR images. Results include a) inventory vector layers to be obtained from a photo-interpretation, i.e. process recognition and type of rock; b) requirements on both, data to be used in an interferometric analysis and on the characteristics of the area of interest which could affect the resulting displacement. From each studied case, learnt lesson were used to generate the guidelines to extract information to study a generic landslide case using remote sensing. The above generic approach was used to generate several guidelines to be used in a landslide operative monitoring service.
