Résumé
Spatial interpolation is the process of predicting the value of attributes at unsampling sites from measurements made at point locations within the same area or region [Burrough, McDonnell, 1998]. To review and to compare spatial deterministic interpolators used in Geographical Information Systems (GIS) such as B-Splines, Fourier, TIN, IDW and polynomial trend surfaces is the main goal of this short article. Some computational technical aspects are examined, as well.
