Hierarchical interpolation techniques allow the efficient representation of digital terrain data. Due to the inherent adaptivity of these methods, less points are needed for the storage of smooth areas compared to non-adaptive methods. They also allow the derivation of approximate terrain models with variable level of detail. This results in a significant compression of the data as well as a highly reduced computational cost of algorithms for terrain analysis.
