The number of nearest observations that should be used for a kriging prediction or simulation, where nearest is defined in terms of the space of the spatial locations.

If the number of nearest observations within distance maxdist is less than nmin, a missing value will be generated see maxdist If loc.dist is specified, maxdist should be in same distance unit. Maxdist is in km when longlat is TRUE (non-projected crs), in meters otherwise. Maximum distance radius for neighbours search in the idw interpolation. Specify the inverse distance weighting power. Matrix of distances between data (rows) and locations (cols) Not necessary with loc.dist.Ĭoordinates of points where to provide predictions. Vector of values to be interpolated at data coordinatesĬoordinates of observation points.
