Surveyed roads need to be verified

Surveyed Road

Nominated Road

• Many surveyed roads have deviated from the original alignments nominated by the regions and districts

• Some additional roads have been added on the day of the road survey

• These roads need to be verified by regional staff

• Some roads may be taken off the final cut of data

Some roads captured in multiple sections(due to other roads intersecting the surveyed road)
