Lineage
The DEM has had a shiny colour drape algorithm applied in ERMapper® to produce an image that has then been reduced to 256 colours to minimise storage on disk. Tiles over disturbed areas have a one metre cell size, those over primary rainforest have a five metre cell size. There is one 4 kilometres by 4 kilometres tile number 2469 for the north eastern quarter of the Island, with the rest being 2 km x 2 km except for some partial tiles along the coast. The colour range for each individual tile has been optimised so as to give a maximum of information a consequence of this is that colours may not match at adjoining edges. Further TIFF images like these can be prepared on a cost recovered basis. In October 2003 this dataset was converted to the MGA(GDA94) projection using an x y shift (550015 = x, 8780001 = y) on the CIG85 projection.
