WebWe would like to show you a description here but the site won’t allow us. WebStarting with sf version 1.0, if you provide a spatial object in a geographical coordinate reference system, sf uses the new package s2 (Dunnington, Pebesma, Rubak 2024) for spherical geometry, which has functions for computing pretty much all measures, predicates and transformations on the sphere. This means:
