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.

Abstract: A sand sea where winds create an endlessly moving collection of long dunes, like waves on the surface of water: this is the landscape of transverse dunes that we can see in Peru by means of satellite images of Google Earth. Here we will show some examples of these dune fields. Keywords: Sand dunes, Transverse dunes, Peru, Barchans, Google Earth.
