This imagery is 15m, six-band multispectral, cloud-minimised mosaics of Landsat 4 satellite scenes over mainland New Zealand.
Component ortho-rectified Landsat 4 scenes in UTM projection were sourced from the U.S Geological Survey. Bands: 1 (Blue), 2 (Green), 3 (Red), 4 (NIR), 5 & 6 (SWIR) Note: All bands are oversampled to 15m using cubic-convolution resampling from nominal 30m. Pan-sharpening, ortho-rectification to NZGD1949 New Zealand Map Grid projection, atmospheric correction, BRDF correction, cloud-clearing, date-prioritising and cloud-minimised mosaicking completed by Landcare Research NZ. The NZMG mosaic was subsequently tiled, each tile re-projected to NZGD2000 New Zealand Transverse Mercator and re-mosaicked.
