  abstract = {{T}he rapid wastage of mountain glaciers and their contribution to sea level rise require worldwide monitoring of their mass balance. {I}n this paper, we show that changes in glacier thickness can be accurately measured from satellite images. {W}e use {SPOT} image pairs to build {D}igital {E}levation {M}odels ({DEM}s) of the {M}ont {B}lanc area ({F}rench {A}lps) for different years. {T}o register the {DEM}s, we adjust their longitude, latitude and altitude over motionless areas. {T}he uncertainty of the thickness change measurement is greatly reduced by averaging over areas covering altitude intervals of 50 m. {C}omparisons with topographic profiles and a differential {DEM} from aerial photographs obtained on the {M}er de {G}lace indicate an overall accuracy of 1 m for the thickness change measurement. {B}elow 2100 m, satellite {DEM}s show an evolution of the thinning rate from 1 ± 0.4 m.a?1 (years 1979-1994) to 4.1 ± 1.7 m.a?1 (2000-2003).},
