What's New

ISEA–H3 crosswalk and per-cell area

  • New h3_crosswalk(): bidirectional mapping between ISEA and H3 cell IDs, with automatic resolution matching and per-cell area comparison
  • New cell_area(): returns geodesic area (km²) for each cell — constant for ISEA (equal-area), location-dependent for H3, with session-scoped caching
  • HexData $cell_area_km2, [["cell_area_km2"]], and as.data.frame() now return per-cell areas for H3 grids instead of the grid-wide average
  • One-time session message when creating H3 grids to inform users that H3 cells are not exactly equal-area
