Spatial Interpolation by Inverse Path Distance Weighting
Generate a cost Raster
Generate interpolation error stats from validation datasets
Inverse Path Distance Weighting
Inverse Distance Weighting with custom distances
Generate a stack of path distance raster objects
Remove NA points features and drop corresponding raster stack layers
Functions are provided to interpolate geo-referenced point data via Inverse Path Distance Weighting. Useful for coastal marine applications where barriers in the landscape preclude interpolation with Euclidean distances.
