DESCRIPTION:Uber H3 has revolutionized spatial indexing\, but its cell size
 s vary a lot. I will introduce IGEO7\, an aperture 7 hexagonal equal-area 
 DGGS with its hierarchical indexing system Z7. It is now implemented in th
 e open-source software  DGGRID and has a handy Python wrapper\, dggrid4py.
