INDEX ONLY: These footprints are the index for the 'Sentinel2 2020 Chatham Islands' mosaic. It has been provided to enable users to explore coverage and capture dates of the component imagery. To enquire about ordering the imagery itself, please e-mail lucas[at]mfe.govt.nz.
The imagery represented is a 10m, ten-band multispectral, cloud-minimised mosaic of Sentinel 2A and 2B satellite tiles over Chatham Islands made from scenes captured late-2019/early-2020.

Component ortho-rectified Sentinel 2A and 2B tiles in UTM projection were sourced from the European Space Agency (ESA). Bands: 1 (“B2” 490nm), 2 (“B3” 560nm), 3 (“B4” 665nm), 4 (“B5” 705nm), 5 (“B6” 740nm), 6 (“B7” 783nm), 7 (“B8” 842nm), 8 (“B8a” 865nm), 9 (“B11” 1610nm), 10 (“B12” 2190nm) Note: All bands not already 10m resolution are pan-sharpened to 10m from nominal 20m. Pan-sharpening, conversion to NZGD2000 Chatham Islands Transverse Mercator projection, atmospheric correction, BRDF correction, cloud-clearing, date-prioritising and cloud-minimised mosaicking completed by Manaaki Whenua - Landcare Research.
Footprints were derived by vectorising (simplified) the mosaic's raster control mask using Esri ArcGIS.
