Spatial Matching
Match parcels to properties using geometry and location rather than identifiers (PIN/ARN).
Toronto Open Data property boundaries lack PIN/ARN identifiers. Spatial matching uses geometry containment (point-in-polygon) and proximity to link parcels with properties based on their location coordinates.
Match Parcels → Properties
For each unmatched parcel, find the property whose coordinates fall within the parcel boundary. Uses point-in-polygon test followed by proximity matching.
Match Properties → Parcels
For each property with coordinates, find the parcel that contains that point. This is useful when you have property records without parcel links.
Enrich Parcels with Address Points
Toronto Open Data provides an Address Points dataset with street addresses and coordinates. Upload this file to assign addresses to parcels that contain each address point. This enables fuzzy address matching for parcels that lack identifiers.
