This imagery is a 10m, four-band multispectral, cloud-minimised mosaic of SPOT 5 satellite scenes over Chatham Islands captured late-2008.
Component SPOT 5 scenes were ortho-rectified to CITM2000 Chatham Island Transverse Mercator using the ERDAS IMAGINE AutoSync module. Ellipsoidal heights were taken from a 15m digital elevation model (DEM) and aerial orthophotography was used for horizontal reference. Bands: XS1 (Green), XS2 (Red), XS3 (NIR), SWIR. Note: SWIR pan-sharpened to 10m from nominal 20m. Pan-sharpening, atmospheric correction, BRDF correction, cloud-clearing, date-prioritising and cloud-minimised mosaicking completed by Landcare Research NZ.
