restitution. And topographic mapping at scale of 1/50 000 M 
and lower. For a better validation of this study, it useful 
JUI 
to undertake the same experience but using areas with 
variable terrain topography and a dense vegetation cover.. 
We also recommend to undertake similar researches 
using aerial photographs at scale of 1/20 000 and larger.
