An interpolation technique is implemented which is applicable to terrain data defined on a rectangular grid. The technique also allows for data compaction, i.e., effectively representing the given data using less space than required by the raw data. The technique involves finding bicubic polynomials which represent the terrain surface over small subgrids. These surfaces are then pieced together to form a global surface which is both continuous and smooth over the entire region. Author
