Abstract
This dataset provides a seamless cloud-free 10m resolution satellite imagery layer of the New Zealand mainland and offshore islands.
The imagery was captured by the European Space Agency Sentinel-2 satellites between September 2018 - April 2019.
**Technical specifications** It comprises 450 x ortho-rectified RGB GeoTIFF images in NZTM projection, tiled into the LINZ Standard 1:50,000 tile layout.
- Satellite sensors: ESA Sentinel-2A and Sentinel-2B - Acquisition dates: September 2018 - April 2019 - Spectral resolution: R, G, B - Spatial resolution: 10 meters - Radiometric resolution: 8-bits (downsampled from 12-bits)
This is a visual product only. The data has been downsampled from 12-bits to 8-bits, and the original values of the images have been modified for visualisation purposes.
If you require the 12-bit imagery (R, G, B, NIR bands), send your request to eo@linz.govt.nz
Purpose
The purpose of this pilot satellite imagery dataset is to assist LINZ in assessing the value of ongoing release of this data to help customers create improved products and services.

The satellite imagery mosaic was created by the European company Sinergise that owns and operates the Sentinel Hub (www.sentinel-hub.com). The producers have used the cloud-free images recorded by ESA Sentinel-2A and -2B satellites between September 2018 - April 2019.
This dataset is only a visual product, meaning that the actual values of the satellite images have not been maintained when the mosaic was created. The values of the data have been downsampled from 12-bit (the actual radiometric resolution of Sentinel-2 sensors) to 8-bit (the resolutionof the data available for download).
If you require the four bands with actual values (R, G, B and NIR, at 12-bit radiometric resolution) contact us at eo@linz.govt.nz and we will send you a download link.
