The flood plains indicate the area of land inundated by runoff in a storm event that has a 1 percent or greater probability of occurring in any given year, assuming maximum probable development (MPD) and future climate change. The flood plains are mapped from hydraulic modelling results. Information specific to each flood plain is accessible using the Identify tool, including the flood report. This dataset is continually updated at catchment scale to reflect the best information available.This dataset is updated by the Heathy Waters team on a regular basis.Disclaimer: In using the Catchments and Hydrology data set, you acknowledge that you have read, understood and agreed to the disclaimers below.The flood plains and flood sensitive area data layers are generated from catchment level modelling based on the datasets, requirements and technology available at the time of model build. They are compiled regional layers with varied data uncertainty and currency, which may directly impact data accuracy for the area of interest. The information provided therefore does not preclude the need for appropriate site-specific assessment and cannot be construed as an endorsement or approval of any development by Auckland Council.The Catchments and Hydrology data set is updated regularly when new information becomes available. As such, downloading and copying activities may result in data invalidity.Whilst due care has been taken in producing the Catchments and Hydrology data sets, Auckland Council gives no warranty as to the accuracy and completeness of any information given and accepts no liability for any error, omission or use of the information.

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• Closed tracks are defined as being no longer maintained or passable and should not be used by recreationalists.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.

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 Auckland Urban Stream Survey – conducted by the Waterways Centre between April 8 and 9, 2024 – delivered high-resolution, high-fidelity terrain models to support Auckland Council’s Making Space for Water initiative. Waterways Centre used a bidirectional gridded acquisition flight plan using the VUX-240 sensor to capture LiDAR data of the Pakuranga Creek and Cockle Bay catchments as well as the eastern portion of the Whau catchment (Blockhouse Bay). A dense colourised 3D point cloud data was generated along with a push-button orthophotography at 0.1 m resolution.

The 1:1,000,000 scale Vegetative Cover Map of New Zealand is the first vegetation survey which can be applied nationally for planning, research, and education. It optimises the cartographic potential of the vegetation information available in the early 1980s and provides a historical record which will aid in future analyses of vegetative cover and land utilisation. The map classification recognises 47 Vegetative Cover Classes identified by alphanumeric code and 17 Vegetative Cover Elements identified (only on the printed map) by symbols and patterns. The map is published as two sheets 730mm x 880mm covering the three principal islands of New Zealand and all offshore islands within 100km of the coast. The map was accompanied by a 153 page, illustrated, book which discusses New Zealand's vegetation and describes the 47 classes.

The book to accompany this dataset is available as an epub from: https://mebooks.co.nz/index.php?route=product/product&product_id=402 .

Seven legacy systems were migrated to Auckland Council’s GIS environment where the creation of new assets and maintenance of existing assets are now being undertaken. Using asbuilts sent to the stormwater team from development engineers and/or internal projects, the geometry and attributes of stormwater assets are captured using standard ArcGIS editing functionality. Whilst due care has been taken to capture the assets as accurately as possible, the data is indicative and cannot be considered to align to any particular boundaries or features including cadastral.
