WebApr 11, 2024 · The best-performing model is the model with bathymetry input and coarse-to-fine architecture. It was compared with two deterministic methods of reconstructing area2 using images of 3 days. The result demonstrated that the model outperformed traditional interpolation methods, especially in areas outside the data coverage.

Inverse distance weighting (IDW) is a type of deterministic method for multivariate interpolation with a known scattered set of points. The assigned values to unknown points are calculated with a weighted average of the values available at the known points. This method can also be used to create spatial weights matrices in spatial autocorrelation analyses (e.g. Moran's I). The name given to this type of method was motivated by the weighted average applied, since it r… WebThere are two main groupings of interpolation techniques: deterministic and geostatistical.
