Extract Centerline from Closed Polygons R package centerline version 0.2.5 CRAN Task View: Spatial (https://CRAN.R-project.org/view=Spatial) Generates skeletons of closed 2D polygons using Voronoi diagrams. It provides methods for 'sf', 'terra', and 'geos' objects to compute polygon centerlines based on the generated skeletons. Voronoi, G. (1908) <doi:10.1515/crll.1908.134.198>.
