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.

This vector data layer spatially represents a subdivision of geologic ages using the framework of the International Geological Time Scale. It depicts a standard scale used to express the history of the Earth. This layer was constructed using EPSG:4978 (WGS 84). It is also suitable for projection in EPSG:3031 (WGS 84/Antarctic Polar Stereographic). DOI https://doi.org/10.21420/7SH7-6K05

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.

This layer is a geological map bibliography for Antarctica. It was produced by GNS Science in conjunction with partners in the SCAR GeoMAP project. It represents the sources referred to in the classification of geological map polygons. This layer depicts a selection of key maps, as polygon outlines with data providing links to original bibliographic source, that have been useful to the GeoMAP team. It shows the majority of, but not necessarily all, geological maps available for Antarctica. The dataset comprises polygons with each having attributes describing the source's authors, title, publication, year, program and scale of publication. The data structure complies with the GeoSciML 4.1 standard where relevant and uses the relevant CGI Controlled Vocabularies.The GeoMAP dataset was produced as part of the Regional Geological Map Archive and Datafile, one of the Nationally Significant Collections and Databases supported by the New Zealand Government’s Strategic Science Investment Fund (contract C05X1701).DOI https://doi.org/10.21420/7SH7-6K05

This collection of datasets comprises geological information for Antarctica. They have been compiled by the GeoMAP team led by GNS Science. This work utilsed co-funding from GNS Science's Nationally Significant Databases and Collections Programme (NSDC) and international collaboration through the SCAR GeoMAP project. It represents a synthesis of existing published and unpublished mapping of the geology of this area in a single geodatabase at a regional scale. The data comprises geological unit polygon geometry and attribute fields describing the unit type, name, age, lithology, stratigraphy, and supporting background information, where this is known and geological fault polyline geometry and attribute fields describing locational accuracy, exposure, fault type, and supporting background information, where this is known.

Abstract: The Coastal Inundation dataset maps the extent of sea water coverage expected around the coastal areas of the Auckland Region during storm events. It replaces the existing inundation extent currently (July 2018) published on Geomaps. The new data published has been derived from analysis carried out by NIWA in 2016/2017.A description of the derivation of the data is here: U:\COO\IES\STW\SW CAMP\Flood Planning Team\Coastal Inundation Analysis\DELIVERY FILES 2017\Stage III\Onde Drive Folder\CoastalInundation\MemoDeliveryReport_Final.pdfLineage: The flood levels derived by NIWA in the report Coastal Inundation by Storm Tides and Waves in the Auckland Region. June 2016. Technical Report 2016/2017 (Part 2)were used to establish the inundation water levels expected around the region. These levels were projected onto the land topography to establish the extent of coastal flooding.The land topography was derived from the 2013 LiDAR survey or 2006 LiDAR survey. The additional analysis of the Parakai Harbour area (described in Part 3 of the above report) was not published, as a higher density of LiDAR land topography is expected to be available in 2018, which will improve the accuracy in this area when it becomes available.Update Cycle: Adhoc when improved data becomes available.This data is available to the public on the Geomaps viewer and is copied into LIMs
