This imagery is 10m, four-band multispectral, cloud-minimised mosaics of SPOT 5 satellite scenes over most of mainland New Zealand.
Component SPOT 5 scenes were ortho-rectified to NZGD2000 New Zealand Transverse Mercator using the ERDAS IMAGINE AutoSync module. Ellipsoidal heights were taken from a national 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.
