Method

How it works

Checks JSON, geometry type, ranges and ring closure.
Point out potential self-intersections without altering the original.
Only applies the ring lock when the user confirms it.

Limits

Sources and scope

It does not infer CRS, does not silently remediate, and does not assess deforestation, legality, country risk, or EUDR compliance.
