Data has been created from hosted feature service (https://mapping.gw.govt.nz/arcgis/rest/services/GW/NRPMap_P_operative/MapServer). It has been shared to the Open Data Portal. This feature class shows water races in the Wairarapa which are subject to Rule LW.R141 that permits the taking and use of water from water races provided the take and use is authorised by a resource consent held by the district council controlling the water race. The water races are identified in the following consents held by district councils in the Wairarapa:

This data shows the outline of all buildings located in the Wairarapa districts in the Wellington region as viewed from aerial photography capture in 2013. The processed data was added to preexisting outlines created for flood modelling purposes. Both datasets were used in the Greater Wellington Regional Council topographic base map layers used on Landinfo3 and the Greater Wellington external mapping webmap.

Building outlines were received from the western half of the Wellington region but had not been created for the eastern half. Prior to this data collection, the only sections of the Wairarapa urban areas that had building outlines were Masterton CBD, Masterton Eastside and Westside which had been created by George Harley to use in flood modelling exercises.

Building outlines in Featherston were derived by using the Image Classification tool on 2013 Aerial Imagery from New Zealand Aerial Surveys. Areas classified include vegetation, road & pavement, building and bare earth. Building polygons were extracted and edited to show only the outline of buildings.

The remainder of the outlines were created in ArcGIS Pro by tracing the outline of the buildings as shown in the 2013 Aerial Imagery. The outlines were initially created using the Right Angle Line tool unless the building appeared irregular enough to warrant the use of the standard polygon drawing tool.

Active fault traces mapped using 1 m resolution Light Detecting and Ranging (LiDAR) Data commissioned in 2013 by Greater Wellington Council. The revised mapping is focused on previously-mapped faults and near towns in the Wairarapa Valley. From these fault traces, Fault Avoidance Zones have been developed for faults in and around the main towns and selected previously mapped faults, and Fault Awareness Areas for the remainder. The mapping was undertaken for land use planning purposes as one natural hazard dataset for a revision of the Combined District Plan.

Orthophotography of the urban areas within Masterton, flown in January 2021.

Imagery was captured for the ‘Masterton District Council’ by AAM NZ Limited, 6 Ossian St, NAPIER, New Zealand.

Data comprises:

• Imagery Area: 92.448 km2 • 1070 x ortho-rectified RGB GeoTIFF images in NZTM projection, tiled into the LINZ Standard 1:500 tile layout

•Tile layout in NZTM projection containing relevant information.

The supplied imagery is in terms of New Zealand Transverse Mercator (NZTM) map projection. Please refer to the supplied tile layout shape file for specific details, naming conventions, etc.

Imagery supplied as 7.5cm pixel resolution (0.075m GSD), 3-band (RGB) uncompressed GeoTIFF.

The final spatial accuracy is ±0.2m @ 90% confidence level.

1m elevation contours based off a composite bare-earth LIDAR DEM of Wellington Region, New Zealand, 2020. Vertical datum is NZVD2016. Area of 50k topo sheet BP34 (Masterton).1m elevation contours based off a composite bare-earth LIDAR DEM of Wellington Region, New Zealand, 2020. Base DEM is the 2013 WAGGIS LIDAR regional DEM, reprocessed in 2017 by Landcare Research for LINZ. Additional, mainly later, DEMs have been mosaiced in to replace the regional DEM where possible, in this sheet based off data from Masterton urban (2016). Original region-wide 2013 LIDAR data captured at 1.3 points per square metre, to an accuracy of +/- 0.15m (1 sigma) in 2013-2014.Subsequent more localised LIDAR surveys have provided improved strike point densities and accuracies.Vertical datum is NZVD2016. Projection NZTM. Parent DEM cell size 1m. Contours have been smoothed by first applying focal statistics to the parent DEM (3x3 cell, mean), then generalising the resulting contours using the Douglas-Peucker method.

Data has been created from hosted feature service (https://mapping.gw.govt.nz/arcgis/rest/services/GW/NRPMap_P_operative/MapServer). It has been shared to the Open Data Portal. The map is based on a model for the distribution of air pollutants in Masterton. The limit of air pollution (from domestic fires) follows the boundary of the town urban area. The model was developed by Neil Gimpson, Golders and Associates and Tamsin Mitchell, Greater Wellington Regional Council.
