The vegetation mapping project used a set of 1987 and 1980 orthophotos and orthophoto mosaics for mapping and screen-digitising (see "Quality" section). Contact AADC for access to these. A shapefile of orthophoto coverage shows polygons for the areas where each orthophoto was used for mapping. This is an essential guide for use when matching the vegetation polygons to the correct orthophotos.

A list of the orthophotos and orthophoto mosaics used for the vegetation mapping, with locations, is as follows: ('orthoantc' signifies 1987 series, 'orthocasc' signifies 1980 series. Run numbers are not included. Frame numbers are signified by 'f').
