Description
A seamless topographic colour map service covering Australia, its outer islands, external territories, and the Australian Antarctic Territory. The service integrates data from Geoscience Australia, the Australian Antarctic Division, OpenStreetMap, and other sources, portraying cultural, hydrography, marine, transport, vegetation, and relief themes. The topographic information was checked in 2008 and supplemented in 2009, with limited field checking noted.
Use Cases
Create thematic maps based on integrated cultural, hydrographic, and relief data.
Analyze land cover and vegetation patterns using the aggregated ACLUMP vegetation layer.
Visualize transport networks and infrastructure using combined Geoscience Australia and OpenStreetMap road data.
Generate relief visualizations using processed SRTM DEM data with stripe removal and void filling.
Strengths
Covers a comprehensive geographic area including mainland Australia, external territories, and the Antarctic Territory.
Integrates data from multiple authoritative sources including Geoscience Australia, Australian Antarctic Division, and OpenStreetMap.
Includes detailed themes such as cultural features, hydrography, marine data, transport, vegetation, and relief.
Limitations
Topographic information was last checked in 2008-2009 with limited field checking, so some features may not be accurate.
Description metadata is limited; actual data quality and structure require manual inspection after download.
Scale-dependent data sourcing (e.g., GEODATA TOPO 250K beyond 1:100,000 scale, OpenStreetMap from 1:100,000 scale) may cause inconsistencies.
Provenance
Source
Geoscience Australia, Australian Antarctic Division, OpenStreetMap, Australian Bureau of Statistics, Natural Earth.
Collection Method
Aggregated from multiple mapping datasets and programs, including NATMAP Topographic Mapping and ACLUMP.
Time Range
Topographic information checked in 2008-2009; SRTM data acquired February 2000; suburb data from 2018 and 2020.
Freshness
Last updated 2026-06-04 07:39:39.666567; freshness should be verified.
