This imagery is a 10m, four-band multispectral, cloud-minimised mosaic of SPOT 5 satellite scenes over Chatham Islands captured early-2012.
Component SPOT 5 scenes were ortho-rectified to CITM2000 Chatham Islands Transverse Mercator using the ERDAS IMAGINE AutoSync module. Ellipsoidal heights were taken from the Landcare Research 15m digital elevation model (DEM) and aerial orthophotography was used for horizontal reference. Bands: 1 (Green), 2 (Red), 3 (NIR), 4 (SWIR) Note: Band 4 (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.
