Analysis of the Motion of Some Brazilian Coastal Dunes

Author(s): Amelia Carolina Sparavigna

Satellite images of coastal dunes of Brazil are showing an interesting feature. As we can see from images of Google Earth, these dunes are leaving, during their motion, some footprints behind, which are sedimentary patterns. Then, we can use the Google Earth images to follow year after year the motion of such dunes. Here we give some examples of the analysis we can perform on such satellite images, in particular for a remote monitoring of these moving dunes.
