Bilinear interpolation (or bilinear resampling) uses 4 nearest neighbors to generate an output surface when you resample or reproject rasters.
The prediction is strong in kriging. In this guide to geostatistics we embark on a journey to sculpt a legendary prediction model with kriging interpolation
In the case of a semi-variogram, closer things have less variability and are similar. While things farther away are less predictable and are less related.
Inverse Distance Weighting (IDW) interpolation estimates unknown values with specifying search distance, closest points, power setting & barriers.
