3D Earth, hexagons by H3 cell. Each populated cell carries the DIMMs reporting from that geographic point.
Colored markers are the ~50 government NMDB neutron monitor stations — cyan = polar / solar-sensitive, red = equatorial / galactic-only. Our sensor hexes complement that fixed network with a denser participant grid.
Walking skeleton. Altitude shells, frustum cull, and real-time data polling land in upcoming iterations.
