Pairwise Hausdorff distance

Source: R/extendr-wrappers.R
ga_dist_hausdorff_pairwise.Rd

The Hausdorff distance measures how far two geometries are from each other by taking the maximum of all minimum distances between points on the two shapes.

Usage

ga_dist_hausdorff_pairwise(origin, dest)

Arguments

origin

a GeoArrow geometry array

dest

a GeoArrow geometry array; length 1 or the same length as origin

Value

a double vector of Hausdorff distance values

References

Examples

# how far apart are neighbouring counties at their worst?
fp <- system.file("shape/nc.shp", package = "sf")
nc <- as.data.frame(read_shapefile(fp))

as.vector(ga_dist_hausdorff_pairwise(nc$geometry[1:5], nc$geometry[2:6]))
