National Road Centreline and RCA attributes - field descriptions
The dataset updates every month.
Data reuse caveats: as per license.
Data quality statement: the October 2018 release holds 76% of RCA attribution; we are still working with the remaining RCAs to include their data.
Data quality caveats: for API explorer users, there is a known issue with number-based attribute filters where the “AND” operator is used instead of the “BETWEEN” operator. Substituting “BETWEEN” for “AND” manually in the query URL will resolve this.
