MDA uses remote sensing to assess hurricane damage, track volcano mudslides and map flood risk. Case studies include Hurricane Mitch and the Casita Volcano in Nicaragua.
Remote sensing and GIS technologies were used to assess the areal extent of Hurricane Mitch damage due to flooding and mudslides. Landsat and RADARSAT imagery were used for selected area pre- and post-hurricane agriculture and banana plantation conditions. Merged SPOT Pan and XS image data and RADARSAT were used in the analysis of the Casita Volcano mudslide.
A GIS analysis based on precipitation data and a shaded relief Digital Elevation Model provided thematic maps for the entire country covering Areas at Flood Risk, particularly Agricultural Areas, Flooding Probability, Probable Flood Damage, and Potential Transportation Risk.
