Abstract
This paper describes the fractal-based analysis and interpolation of 3D natural surface shapes and their application to terrain modeling in a sensor simulation for an earth resource satellite. After introducing the fractional Brownian function as a mathematical model for describing natural fractals and discussing its properties, we present fractal-based techniques for analyzing and interpolating 3D surface shapes. These techniques are essentially based on the approximation of the surface by the fractional Brownian function. Finally, the application of these techniques to terrain modeling is described. The analysis-followed-by-interpolation method is successfully applied for generating the digital terrain map of high spatial resolution from the existing coarse terrain data.
