- inversedistance ; for inverse distance weighted interpolation between available values at spatially distributed locations.
- bilinear ; for bilinear interpolation between available values at spatially distributed locations.
- kriging ; for interpolation using Kriging between available values at spatially distributed locations.
- gridcellavaraginggridcellaveraging; for interpolation of time series based on averaging grid cells (used for example for establishing catchment averages where the catchment size is much larger than the grid cell size).
- Closest distance; for interpolation of time series based on the closest distance between available values at spatially distributed locations. An extra option is to interpolate from a grid to a longitudinal profile.
