Abstract

A terrain modeling system provides a terrain model having variable resolution. The system receives an input terrain made up of raster points. The system identifies raster points that differ in height from an adjacent raster point by a threshold. The system interpolates the identified raster points to calculate one or more B-spline surfaces. The surfaces correspond to a multi-dimensional representation of a physical terrain.
