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.
