This imagery is 10m, four-band multispectral, cloud-minimised mosaics of SPOT 5 satellite scenes over mainland New Zealand. Scenes have been stacked to give late-2012 capture dates priority where possible.
Component SPOT 5 scenes were ortho-rectified to NZGD2000 New Zealand Transverse Mercator using the ERDAS IMAGINE AutoSync module. Ellipsoidal heights were taken from the Landcare Research 15m digital elevation model (DEM) and 2008/2009 SPOTMaps was used as the reference image. 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.
