  • 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 2019 - April 2020. **Technical specifications:** - 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 2019 - April 2020 - 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.

  • New Zealand Tsunami Database includes information about tsunamis that have reached the coastline of New Zealand since humans arrived in this land until the present day. The database is primarily the work of historical seismologist Gaye Downes working for GNS Science who collected reports of tsunamis around New Zealand and, in many cases, carried out research to determine parameters of the source, travel time and impact associated with each event. Reports of tsunamis that make up the core of this database come from tide gauges, newspaper articles, harbour masters, records from ships, personal diary entries and Māori oral records. This primary source material is summarised in the database and complete transcriptions are held by the database custodian. DOI: https://doi.org/10.21420/D6W9-0G74 Cite as: GNS Science. (2020).
