Abstract : Digitized terrain data corresponding to a given geographical area are generally available in a rectangular grid at some fixed resolution. In the modeling and simulation of processes that interact with terrain, it is often desirable to model the terrain at a higher resolution. Unfortunately, it is impossible to discern terrain features smaller than the resolution of the data. In this report the author uses the variable resolution terrain model to do the next best thing. He constructs a continuous terrain surface that matches the terrain data to a prescribed tolerance and simultaneously includes in that surface realistic terrain features smaller than the resolution of the data.
