| Abstract: |
The PGF lidar 2021 dataset is a whole-of-region lidar acquisition captured Jan-March 2021. The dataset was acquired as a collaborative venture between LINZ, Waikato Regional Council and affected District Councils. The dataset was flown with the intension to cover the region with laser height sampling points at a rate of 4 pulses per square meter (but with achieved point density varying in dense vegetation), and at a height accuracy of 0.2m with respect to the NZVD2016 datum at 95% confidence (0.1 m RMSE). The dataset was flown in blocks that dissect the region into manageable chunks, and currently the lidar is stored by Council according to these as-supplied blocks. A future plan is to integrate the blocks into a single regional dataset record.
The dataset comprises 4 core products – a digital elevation model (DEM) providing a 1m tiled grid (tif) of ground heights; a digital surface model (DSM) providing a 1m tiled grid of surface topmost height (e.g., the top of vegetation); a tiled classified point cloud (PC); and a set of half-meter cartographic contours. Tiling of DEM, DSM and PC is according to the LINZ 1K tile dataset here: https://data.linz.govt.nz/layer/104692-nz-11k-tile-index/
The lidar data was collected according to the specification listed in the January 2020 version of the LINZ lidar national specification document (the current version can be found here):
https://www.linz.govt.nz/resources/guide/new-zealand-national-aerial-lidar-base-specification
For access to the data by external parties, the DEM, DSM products are available at the LINZ data service here and the PC can be downloaded here:
Derived products under development by WRC include a normalised digital surface model (nDSM) as the calculation of DSM-DEM providing the height of vegetation and other surface material above ground level; an intensity raster providing a location-accurate black and white image of object position; a watershed and river network resource; a hydraulically corrected DEM for flood modelling; a slope-segmentation layer; and set of half-meter engineering contours (the core product contours are cartographic/smoothed for clean interpretation). These and others will be added to the feature set listed under this metadata item as the products are completed.

| Abstract: |
Polygons used by the vendor during processing to enforce flat (lake, ocean) or leaning (stream) DEM surfaces. Hydroflattening was applied to streams > nominal 30m width and lakes > 10000 sqm, with islands 5000m2 delineated from these polygons, as well as coastal sections. Some islands smaller than this size were delineated by the vendor based on sensible judgement (e.g., rocks). |
|---|
| Statement: |
Currently the lidar is arranged by major block (blocks A-G) so there are seams and overlaps at the block margins, and similarly organised by block. During 2024 the dataset will be integrated to a single regional product after which this hydroflattening vector dataset will also be integrated (i.e., dissolve the seams and overlaps) |
