GeoJSON
GeoJSON
GeoJSON is a standardized JSON-based format for representing geographic features and their properties. It can encode curb-related points, lines, or polygons, while the meaning of attributes, accuracy of boundaries, and legal interpretation remain responsibilities of the dataset rather than guarantees supplied by the file format.
Understanding the term
GeoJSON geometry and curb semantics are different layers. A valid polygon needs documented identifiers and attributes before applications can interpret its permitted activities or effective hours.
An implementation should document its version, identifiers, time conventions, geographic accuracy, and supported fields. Test representative exchanges between the actual participating systems, including exceptions and updates. Assign responsibility for correcting discrepancies between published information, legal records, and the street. Collect only information needed for a defined purpose and apply suitable access and retention controls. A successful technical exchange does not by itself prove that the data is current, legally authoritative, or suitable for enforcement.
