By using high resolution 3″DEM data,precipitation data from May to October of 94 weather stations in the east of Qinghai-Tibet Plateau,based on multivariable stepwise regression method,the estimating model of monthly precipitation are done combined with terrain factors.

Finally the relationship between the baseline and digital elevation information is analyzed.

Based on digital elevation model theory,river system information is extracted by GIS software from DEM.

The theory and method to obtain digital elevation from InSAR image are introduced.

On the basis of statistical fractal theory, we analyze and compute the dimension space, scale ranges and fractal dimensions of a large number of tiny-terrain digital-elevation-model (DEM) data which are got from experiments, and get their terrain-characteristic data.

The detection error in line-of-sight caused by phase error,DEM error and baseline error is very serious in practice.
