Several methods exist for surveying the dunes and estimate their migration rate. Among methods suitable for the macroscopic scale, the use of the satellite images available on Google Earth is a convenient resource, in particular because of its time series. Some examples of the use of this feature of Google Earth are here proposed.

Footprints of Brazilian Coastal Dunes


The satellite images of Google Earth show an interesting feature of some coastal dunes of Brazil. They are leaving, during their motion, some “footprints” behind, which are sedimentary patterns. In this manner, it is possible to follow year after year the motion of such dunes.
