<p>A polygon data set with <code>sf</code> class.</p>

Functions to produce a fully fledged 'geo-spatial' object extent as a
'SpatialPolygonsDataFrame'. Also included are functions to generate polygons
from raster data using 'quadmesh' techniques, a round number buffered extent, and
general spatial-extent and 'raster-like' extent helpers missing from the originating
packages. Some latitude-based tools for polar maps are included.
