GEODATA TOPO 2.5M 2003: Australian National Topographic Vector Data

GEODATA TOPO 2.5M 2003 is a national seamless vector dataset representing the Australian landscape at a 1:2.5 million scale. The product consists of eleven data layers, including built-up areas, contours, drainage, and transport networks, derived from higher-resolution 250K series data. It was developed by Geoscience Australia according to GEODATA standards and supersedes the 1998 version.

Use Cases

• Create regional-scale reference maps based on the eleven thematic layers.
• Perform national GIS analysis using the seamless vector representation of the landscape.
• Integrate topographic features like roads, rail, and waterbodies into broader environmental models.
• Update legacy maps by utilizing this dataset which supersedes the 1998 product.

Strengths

• Contains eleven distinct thematic data layers for comprehensive landscape representation.
• Developed with double precision accuracy, suggesting high coordinate fidelity.
• Supersedes a prior 1998 product, indicating an updated and standardized version.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
