Porirua City Data

Index Tiles ONLY, for actual orthophotos see layer Porirua 0.10m Urban Aerial Photos (2020)

Orthophotography within the Porirua City urban area in the Porirua City District totalling approximately 139 km2. The area of capture is located within the Wellington Region of the North Island, and captured in the flying seasons (summer period) 2019-2020.

Imagery was captured for Porirua City Council by Aerial Surveys Ltd, Unit A1, 8 Saturn Place, Albany,0632, New Zealand.

Data comprises:
• 1,667 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 10cm pixel resolution (0.15m GSD), 3-band (RGB) uncompressed GeoTIFF. The final spatial accuracy is ±0.15 m @ 95% confidence level.

This layer provides the extents of the data incorporated into an adjustment which has been completed as part of the Spatial Parcel Improvement (SPI) project. The SPI project aims to improve the accuracy of digital cadastral data in areas (primarily rural) where survey-accurate data does not currently exist. The improvement of coordinates is controlled by a mathematical adjustment process using a Least Squares methodology. The adjustment/integration process results in increased mapping accuracy of surrounding spatial objects (e.g. parcels), the effect of which is some new observations or parcels appear to move. The extent of the change largely depends upon the accuracy of the underlying data. In general, movements will be at least several metres, as the SPI project targets areas where significant movements are expected.
