Encode and decode

terminal

e2 cell encode --lat 40.7 --lng -74
  --time 2026-08-18T00:00:00Z --spatial-resolution 9
  --temporal-resolution 1d --feature restaurant

e2 cell decode e2:1:892a13ba46bffff:1d:20677

All commands support the global --json option. The encode command accepts temporal resolutions from 1s through 7d.

Traversal commands

Command	Behavior
`cell neighbors <id> --k 1`	Return spatial neighbors at a grid distance.
`cell previous <id>`	Move to the previous temporal bucket.
`cell next <id>`	Move to the next temporal bucket.
`cell spatial-parent <id>`	Move to the parent spatial cell.
`cell temporal-parent <id>`	Move to the next coarser temporal resolution.
