A line connecting points of equal water depth which is sometimes significantly displaced outside of soundings, symbols and other chart detail for clarity as well as generalization. Depth contours, therefore, often represent an approximate location of the line of equal depth as related to the surveyed line delineated on the source. Also referred to as...

This layer has been provided to enable potential users to identify the coverage of photography for Mainland NZ flown on behalf of the Crown between 1936 and 2005. It shows the extent of each aerial survey undertaken. The Historic Aerial Photos, Photo Footprints (1936-2005) layer shows the extent of each photograph in the survey. See The Crown historic...

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

This table is used to describe the many to many relationship between surveys and parcels. This is a table to link NZ Survey Plans data with spatial parcel layers such as NZ Parcels, NZ Linear Parcels or NZ Primary Parcels. An affected parcel is a parcel which is affected by the approval of a survey dataset. A parcel may be affected, created or...

This dataset provides an index to the Electronic Navigational Charts (ENC) available through the LINZ Data Service showing extent and ENC attributes. The ENC index is compiled from the S-57 Object Class “Nautical publication information” which is used to relate additional nautical information or publications to the data. The attributes are populated by...

This dataset provides information about the position, height, height datum, height accuracy, mark name, mark type, condition and unique four letter identifier for geodetic marks that have an authoritative height in terms of a vertical datum. Heights are in datums defined at http://www.linz.govt.nz/geodetic/datums-projections-heights/vertical-datums/. All...

A deliberately formed route of a lesser quality than a road Data Dictionary for track_cl: https://docs.topo.linz.govt.nz/data-dictionary/tdd-class-track_cl.html This layer is a component of the Topo50 map series.

The NZ Imagery Survey Index dataset provides an index to all orthophoto index tiles found on the LINZ Data Service. Each record in the dataset provides both a geometry of the maximum extent of the orthophoto index, as well as all attributes found in each index tile. This dataset therefore provides information to assess orthophoto coverage and metadata...

This layer provides survey mark information for marks that are not part of a parcel A non-boundary mark is any survey mark that is not on a boundary point. The points in this dataset represent physical survey monuments usually placed for cadastral requirements. The data set also includes geodetic marks. Non-boundary marks now enter the Landonline system...

This layer provides all marks and associated information that have an order of 6 or better. Cadastral surveys are required to connect to these marks if they are within a specified distance. A cadastral survey network mark is a node which is (or was) occupied by a physical survey monument that meets accuracy standards suitable for cadastral requirements....
