The NZ Elevation Survey Index dataset provides an index to all LiDAR derived elevation datasets found on the LINZ Data Service. Each record in the dataset provides both a geometry of the extent of the elevation survey, as well as useful metadata attributes. The extents are derived from the maximum extent of DEM and DSM coverage and consist of full NZTopo50 1k tiles, even where a tile is only partially covered with data. These extents only provide a rough indication of corresponding point cloud coverage which can be quite different for some elevation surveys.

Please refer to the NZ Aerial Surveys Data Dictionary for detailed metadata and information about this dataset.

The elevation data referenced by this dataset is available on the LINZ Data Service.

This dataset was last updated on LINZ Data Service on 13 Jun 2016.

This layer contains the DEM for LiDAR data from the Auckland region captured in 2013.
The DSM is available as layer Auckland Lidar 1m DSM (2013).
The index tiles are available as layer Auckland Lidar Index Tiles (2013).
The LAS point cloud and vendor project reports are available from OpenTopography.

Lidar was captured for Auckland Council by NZ Aerial Mapping & Aerial Surveying Limited. The capture of the data commenced on 17th July and was completed by the 23 November 2013. The datasets were generated by both ASL and NZAM. All raw point cloud data was produced by NZAM & ASL prior to data being sent to Genesys International for the data classification and product generation. The survey area includes the Auckland city urban area and adjacent rural land covering approximately 2250 square kilometers. Data management and distribution external to Auckland Council is managed by Land Information New Zealand.

Data comprises:
•DEM: 6423 asc files in NZTM projection, tiled into a 1:1,000 tile layout
•DSM: 6423 asc files in NZTM projection, tiled into a 1:1,000 tile layout
•Point cloud: 8224 las files in NZTM projection, tiled into a 1:1,000 tile layout

Data was collected at > 1.5 point/square metre point density. Attributes include:
-Elevation
-Intensity values
-Return number
-Adjusted GPS time
-Classification

Vertical accuracy specification is +/-0.2m (@ 95% confidence)
