Publishing community maps without exposing lives

Public release changes what a community map can reveal, even when names are removed. This methods note compares NIST de-identification guidance with Indigenous data-governance and Canadian research ethics sources to examine identification, collective exposure, and inference from omissions. A wholly fictional seasonal-observation case contrasts exact points, displaced points, broad zones, and a non-spatial account. It shows why record counts, contributor counts, and complete release packages require separate scrutiny, and why suppressing one cell may not prevent reconstruction. The analysis favours a purpose-led, authorised derivative rather than automatic export of the source map. It provides neither an anonymisation guarantee nor a universal Indigenous checklist, and identifies changing linkage opportunities, review capacity, and irreversible distribution as important limits.
