This imagery is 2.5m, three-band (B, G, R) cloud-minimised mosaics of SPOT 5 satellite scenes over mainland New Zealand. Note that the blue band is artificial.
Imagery acquired by the SPOT 5 sensor (2.5m Pan, 10m G, R, NIR, 20m SWIR). Scene segments have been orthorectified to the New Zealand Transverse Mercator Geodetic Datum 2000 (NZTM 2000) coordinate system. The multispectral imagery was pan sharpened to create a 2.5m colour image for each segment at the sensor processing level. This 2.5m imagery was imported into Pixel Factory for the orthorectification and mosaicing. Aerial ortho-photography provided by Land Information New Zealand (LINZ) was used for the horizontal ground control. The Landcare Research 15m DEM in NZTM projection provided elevation information. The segments were merged to create a seamless mosaic in which cloud cover was minimised. The segments were contrast matched to reduce join lines and create an 8-bit RGB (pseudo natural colour) image. This mosaic is delivered in tiles which equate to the NZTM 1:50k map sheet tiles.
