interpolation_krigingdrift: Kriging with External Drift interpolation

In MariekeDirk/GeoInterpolation: Temperature Interpolation methods

Description

Function overlays the ground stations and the grid and interpolates using autokrige from the autoKrige.

Usage

interpolation_krigingdrift(groundstations, method.overlay = "extract",
  formula, variable, grid_drift, blocksize = 20000, mxdkrige = Inf,
  mod = "Exp", conditional.sim = FALSE)

Arguments

groundstations	Data from the ground station in spatial format without na values
method.overlay	Method to overlay the points and the grid, choose between over (1 cell) and extract function (which averages over 4 nearest cells)
formula	formula used for the kriging interpolation
variable	the variable of the groundstations you want to interpolate
grid_drift	trend grid for the interpolation with same spatial extent as groundstations
blocksize	kriging interpolation variable, with a standard value of 20000
mxdkrige	kriging interpolation variable, with a standard value of Inf
mod	kriging interpolation variable, standard set to "Exp"
conditional.sim	boolean, TRUE or FALSE. Standard set to FALSE as this simulation takes more time, nmax=30 and nsim=4.

Details

after running this function take a look at get_statistical_summary

Value

returns a list with the kriging interpolation output and a dataframe with the difference between your observations and predicted grid
