Compute the distance between two geometries

Source: R/geom.R
g_distance.Rd

g_distance() returns the distance between two geometries or -1 if an error occurs. Returns the shortest distance between the two geometries. The distance is expressed into the same unit as the coordinates of the geometries.

Usage

g_distance(this_geom, other_geom)

Arguments

this_geom

Character. OGC WKT string for a simple feature geometry.

other_geom

Character. OGC WKT string for a simple feature geometry.

Value

Numeric. Distance or '-1' if an error occurs.

Note

Geometry validity is not checked. In case you are unsure of the validity of the input geometries, call g_is_valid() before, otherwise the result might be wrong.

Examples

g_distance("POINT (0 0)", "POINT (5 12)")
