1m contours for urban Wellington including Makara Beach and Makara Village. Based on a DTM created from 2006 LiDAR and updated using 2009 photogrammetry masspoints and breaklines where significant changes in the terrain were detected. WCC generalised the contours by up to 0.2m in order to reduce the number of vertices in the dataset. Contours generated from LiDAR and photogrammetry should not be used for detailed engineering design.
