IGAC: Remote Sensing Techniques to analyse Landslide Susceptibility
UN-SPIDER's Regional Support Office in Colombia, the Agustin Codazzi Geographic Institute (IGAC), is currently researching the application of Remote Sensing techniques and digital image processing to support the generation of geomorphological information and the location and mapping of critical areas for landslides in Colombia. The project looks at Digital Elevation Models, stereo models, improvements and enhancements using SPOT 5, Rapid Eye, UltraCam-Vexcel and Radarsat-2 sensors. Large parts of Colombia have a high susceptibility to landslides of high impact and frequency due to its geographical, geological and geomorphological characteristics among others. The analysis pilot area focuses on the department of Antioquia, situated in the east of the country.
