Calculates the centroid and radius of a WKT geometry.

Calculates the centroid and radius of a WKT geometry.

calculate_centroid(wkt)

Arguments

wkt	character vector One or more WKT strings with longitude/latitude coordinates (epsg=4326)

Value

Data frame with centroid coordinates and radius in meter.

Details

The centroid is defined as the centroid of the convex hull of the provided geometry.
