spex

Tools for spatial extents that are agnostic regarding format (i.e. sp, sf, or raster). These functions fill some of the gaps within and between these packages for dealing with object extents in flexible ways. Generally, spex considers extents of raster cells, and extents of objects as first-class objects (with projection metadata). and provides helpers for latitudinal boundaries within projected data.
