The 1:25 000 Topographic/Cadastral Map Series portray highly detailed topographic information such as roads, rivers, lakes, vegetation and relief. Also shown is cadastral data, Local Government Area boundaries and locality boundaries which makes these maps invaluable for property related searching.
These maps are an important resource for Government, industry, and the public. They are used for environmental and emergency management, farm planning and mineral exploration. They are also popular for recreational users such as bushwalkers, mountain bike and horse riders.
The Series covers the entire State with 415 maps and is under active revision. Each map covers a 10 x 20 kilometre area with a 1 kilometre grid based on the Universal Transverse Mercator projection (UTM). At this scale, 1 millimetre on the map represents 25 metres on the ground. As maps are revised, they are produced on the new Map Grid of Australia (MGA94) which utilises the Geocentric Datum of Australia 1994 (GDA94). These new maps have an overlapping bleed edge on the northern and eastern sides. This extension fills the gap between the older Australian Map Grid 1966 (AMG66) / Australian Geodetic Datum 1966 (AGD66) maps and the new maps on the GDA94 datum.
