Computation of area and number frequency dimensions of mountains extracted from multiscale digital elevation models
multiscale digital elevation models (DEMs) mountains lifting scheme
2007/12/31
Frequency dimension is used to characterize fractals that come as distinct individual
objects which are spread over a range of space. In this paper, the number and area
frequency dimensions of mount...
Characterization of catchments extracted from multiscale digital elevation models
multiscale DEMs catchments the lifting scheme
2007/12/31
In this paper, the characterization of catchments extracted from multiscale digital
elevation models (DEMs) is performed. First, the lifting scheme is employed to generate
multiscale DEMs. The catch...
