GWRC 1m contours 2020 BR34 (Manurewa Point)

1m elevation contours based off a bare-earth LIDAR DEM of Wellington Region, New Zealand, 2020. Base DEM is the 2013 WAGGIS LIDAR regional DEM, reprocessed in 2017 by Landcare Research for LINZ. Original region-wide 2013 LIDAR data captured at 1.3 points per square metre, to an accuracy of +/- 0.15m (1 sigma) in 2013-2014.Vertical datum is NZVD2016. Projection NZTM. Parent DEM cell size 1m. Contours have been smoothed by first applying focal statistics to the parent DEM (3x3 cell, mean), then generalising the resulting contours using the Douglas-Peucker method.
