DEM has very important military and economy value,grid DEM is the usually represented way.This paper discussed the character of Sierpinski Gasket,according to the characteristics of digital elevation model(DEM),studied the method of Sierpinski Gasket used in DEM information disguise,and analyzed its safety,carried out the disguises process under n dimension Sierpinski Gasket.Then,this paper validated the feasibility through experiments,and found the relation between the impression and some factors.The arithmetic for DEM information disguise has characteristics as strong captivation and good safety,could provide a forceful technique guarantee for DEM's saving and delivering.
