Lineage Statement |
Tiff images were created from printed Topographic series TASMAPS by scanning at 200dpi in 256 colours. The files are geotiffs georeferenced to MGA94, Zone 55 and are supplied with AGD66, Zone 55 and GDA94 world files for ArcView and MapInfo. Some world files have been updated and therefore supersede the geotiff information. Images are current as to the date of printing of the map and the information for each map can be obtained from the index files supplied with the tiff files. |
