In this form, a wide range of surface fitting methods may be used to model the geometric distortion.
- Map Generalization that fits a functional form to the entire data set (e.g., polynomial surface fitting).
- Geometric Facets that construct a map surface by tessellation (e.g., fitting a Triangular Irregular Network of facets to the sample data).
