Criterios pictórico-morfológicos para la identificación de movimientos en masa empleando imágenes de muy alta resolución espacial

Abstract

 Colombia has different geographical, geological or geomorphological, among others, that showing areas of major and minor stability of the earth’s surface; where we found areas of high landslide susceptibility of high impact and frequency. In this way, the project began collecting and studying various methodologies for recognized and in- terpretation landslides; we integrate them with the earth observation technologies, this is used for analysis and generation of pattern from remote sensing images. After evaluating different geodynamic instability areas, the pilot area was delimited in the Antioquia’s Department; therefore, we searched inputs used for the analysis, consid- ering use images of medium and high resolution, such as: SPOT 5, RapidEye and Ultracam-Vexcel. Once established pictorial-morphological criteria, were tested, lo- cating and characterizing different types of landslides, in order to evaluate the strengths and needs added for modeling landslides patterns for satellite images and airborne.
