DESCRIPTION:Modern global geospatial workflows are ill-served by our curren
 t conception of planar geometry.  In GeometryOps.jl\, we have added suppor
 t for operations natively on the sphere (the space ``S²``)\, akin to Goog
 le's s2 library.  This allows us to treat lines as great-circle arcs witho
 ut subsampling\, and calculations like area and intersection are natively 
 non-approximate.  This enables fast and substantially more accurate global
  operations\, especially on areas of particular interest like the poles.
