For extracts of 6 square kilometres or less, use the Extract Data tool on GeoMaps.Contours dataset generated from LiDAR data captured between 2016 – 2018.Vertical datum: NZVD2016Auckland NorthLidar was captured for Auckland Council by Aerial Surveys ASL between August 2016 to August 2018. The dataset was generated by Aerial Surveys and their subcontractors. The survey area includes Auckland CBD, Great Barrier Island, Little Barrier Island, North Shore, Waiheke Island, Wellsford, Whangaparaoa, Whatipu, and the surrounding area.Survey Date: 08/01/2016 - 08/01/2018Auckland SouthLidar was captured for Auckland Council by AAM New Zealand between September 2016 through to June 2017. The original dataset was generated by AAM New Zealand and their subcontractors. The survey area covers the southern Auckland suburbs and regions.Survey Date: 09/09/2016 - 02/06/2017License: Creative Commons 4.0Additional InfoThe vendors’ quality management system for point-location comprised Airborne Global Position System (AGPS for spatial location), inertial measurement unit (IMU for aircraft orientation), and raw laser return (as returns 1,2,3,4) with attributes number/time/angle etc., which allow geometric calculation of actual laser strike location at ground level. AGPS locations were refined by corrections made relative to base stations on the ground. The resultant LAS file (v1.2 format) is an international standard binary package for LiDAR data with return, intensity value, xyz coordinates, and other classification attributes. Target raw point density was 4 points/m2 on open ground with actual density varying around this target depending on ground cover and terrain interference. LiDAR swaths were flown with 25% overlap. Tidal areas were flow within 1.5 hours of gazetted low tide (noting local variation in actual lowest water level). Raw points were classified to ICSM level 3 (99% accuracy on ground point designation), with full class set as per the following Classification [1=unclassified, 2=bare ground, 3= low vegetation, 4=medium vegetation, 5=high vegetation, 6=buildings/structures, 7=low/high points, 9=water, 10=bridge, 12=surplus points at swath overlap].Data are stored in LINZ Topo50 1k tiles (720m x 480m). Enforced levels (‘hydro-flattening’) were applied to static water bodies.Specifications (ASL / AAM): Scan angle (34-36 / 20-29deg); Pulse rate (150/320-330 kHz); Laser footprint size ~0.3; Target lidar ground point vertical accuracy (RMS 0.1m, 95% CL ~ 0.3m); Horizontal accuracy (0.3m); Vertical accuracy from limited validation (95% CL ~0.1, AAM only); DEM / DSM / Intensity grid (1m spacing); Contours (line geometry) 0.25m elevation steps. Coastal and intertidal data was collected at within 1.5 hours either side of low tide.

The Topo50 map series provides topographic mapping for the New Zealand mainland, the Chatham Islands, and offshore islands at 1:50,000 (some of the islands at 1:25,000) scale.

Along with the paper-based Topo50 map series, digital images of the maps are also publicly available.

Georeferenced raster digital images are provided at a resolution of 300 DPI. Georeferencing allows adjacent maps to be accurately and automatically aligned within GIS systems.

Please be aware of the following:

• The existence of a road or track does not necessarily indicate public right of access.

• Closed tracks are defined as being no longer maintained or passable and should not be used by recreationalists. The Department of Conservation or other authorities should be contacted for the latest information on tracks and huts.

• Not all aerial wires, cableways and obstructions that could be hazardous to aircraft are held in the data.

• Contours and spot elevations in forest and snow areas may be less accurate.

• Not all pipelines including both underground and above ground are held in the data or shown on the printed maps. For the latest information please contact the utility and infrastructure agencies

• Permits may be required to visit some sensitive and special islands and areas. Contact the Department of Conservation to see if you need to apply for a permit.

In addition to contour lines, relief shading helps visualise the terrain. Hills and valleys are shaded as if they were illuminated from the north-west.

Relief layers were generated for each sheet, and specifically for use in the Topo50 map series. There may be subtle differences in the relief shading of adjacent map sheets. Where no contour information exists, relief shading has not been produced.

A subset of NationalMap consisting of a combination of historic sites, monuments, and fortification extracted from the LINZ web portal.

The Topographic historic layer consists of the places where there has been historic activity, where there is a historic object, or the structures erected as a memorial can be found in this layer. Also contained are a combination of European fortifications and Maori defensive earthworks extracted from the LINZ web portal. The fortification data consists of: - Redoubt points: European fortification of the New Zealand Wars- Pa points: Defensive earthworks constructed by Maori at any time between the fifteenth and nineteenth centuries which were still visible as a topographical object at the time the first edition of the map was published.

These tiles are raster images of the Topo vector data from Corax Topo 2006 vector dataset, created using ArcGIS in the NZTM projection. They are not the scanned hardcopy maps published by LINZ. All tiles are georeferenced and clipped exactly. Annotation can span the tile boundaries.

The scale of the data is designed to be printed at 1:50,000 but the lower resolutions we have for screens compared to a page means that they are more readable at 1:25,000 scale.

To reduce clutter the patterned filled symbols have been simplified to single colours, contours have been thinned.

Annotation from the topo set has been used for labelling, however that did not include road names, spot heights and descriptive text. These have been placed automatically, so there are some clashes.

Pixel size is 4.0 metres ground which results in much smaller file sizes (~ 40 MB) than a high resolution version of an A1 sheet that LINZ issue from the new series (140 MB)

The tiles are half NZTopo50 sheets, 24 km x 18 km covering 43,200 Ha. The rate set is equivalent to $3.00 + GST per tile or $6 + GST per sheet for large areas. You may find downloading the NZTopo50 index layer to make calculation of the cost easier.

Although there are newer versions of the LINZ data (now v 15) there are very, very few edits in each version, and they are limited to a few tiles, so for most of the country this is still identical to the latest version.
