Service Description:
LiDAR was captured for BOPLASS Ltd by Aerial Surveys from 27 October 2019 to 24 October 2022.  

This Image Service contains the Digital Elevation Model (DEM) processed from the ground LiDAR point cloud, including DEM tiles from neighboring regions.

BOPRC Provincial Groth Fund (PGF) LiDAR Block 1-4 were combined into a single mosaic dataset from Block 1 (Western Bay of Plenty/TCC/Offshore Islands), 2 (Whakatane/Offshore Islands), 3 (Rotorua), and 4 (Opotiki/Offshore Islands). These areas are available for download on the LINZ Data Service. https://data.linz.govt.nz/layer/105690-bay-of-plenty-lidar-1m-dem-2019-2022/  

The purposeful extent of this Bay of Plenty Regional Council (BOPRC) elevation layer is the same as its sister DSM which tends to cover all surface water catchments within the BOPRC Region as depicted from the Draft National Policy Statement for Freshwater Management (NPSFM) Freshwater Management Unit (FMU) boundaries https://maps.boprc.govt.nz/datasets/BOPRC::freshwater-management-units-draft aligned to NIWA REC 2.4 boundaries https://www.arcgis.com/home/item.html?id=28d23ad94c2a4846b7634f4cdbba178f.

Outer region DEM tiles and additional Taupo District elevation tiles falling within the BOPRC region were kindly supplied by the adjacent regions/territorial local authorities (Waikato Regional Council, Gisborne District Council, and Hawkes Bay Regional Council) or acquired directly through the Land Information New Zealand (LINZ) Data Service.

Because the outer-region tiles originated from a different batch/source of processed elevation models, edge artifact and slight discrepancies maybe visible. This will be fixed when National LiDAR point cloud derived surfaces are developed and made available for the tiles between different region captures.

General specifications across this dataset included:

- Pulse density specification is at a minimum of >4 pulses/square meter.

- Vertical Accuracy Specification is +/- 0.2m (95%)

- Horizontal Accuracy Specification is +/- 1.0m (95%)

Vertical datum is NZVD2016.  Projection/Coordinate System: New Zealand Transverse Mercator (NZTM).

The Digital Surface Model (DSM) which includes ground heights is available from the LINZ Data Service at https://data.linz.govt.nz/layer/105691-bay-of-plenty-lidar-1m-dsm-2019-2022/ The LAS point cloud and vendor project reports are available from OpenTopography.org https://portal.opentopography.org/datasetMetadata?otCollectionID=OT.082021.2193.1  

The Elevation Aotearoa story map hosted by LINZ is an excellent resource and can be used to learn about use cases of LiDAR and how to use make the most use of it. https://linz.maps.arcgis.com/apps/MapSeries/index.html?appid=2552c3a5cee24f7b87806b085c3fee8a

This high-quality LiDAR data is also consumed in an Eagle hosted NZ Elevation layer on the ESRI living atlas of NZ and also in the World Terrain elevation layer on the ESRI world living atlas. Consider using these image services in your workflows as supplementary as they may be faster and provide different functionality at different spatial scales. For use in 3d apps and basemaps, consider using the tile layers.
