Geocoding uncertainty
Data qualityAddress-to-point geocoding carries a precision tier (rooftop, street, ZIP centroid) that is often dropped downstream; a ZIP-centroid-precision point treated as rooftop-precision misassigns the cell.
Detection
Geocoder confidence/precision field below rooftop/parcel tier.
Mitigation
- Carry the geocoder precision tier through the pipeline
- Cap effective H3 resolution to match the geocode precision tier, never index finer than the input warrants
Affected conversions
