Calculate the pairwise distances between the centroids of the raster grid cells that a set of points fall into. This is useful as an alternative to the distances between the points themselves, if distances are going to be compared to other metrics that are based on cell centers (e.g. wind connectivity).
Examples
rose <- windscape_example("wind_rose")
sites <- cbind(c(-110, -100, -95), c(35, 40, 45))
cell_distance(rose, sites)
