Olary Topographic Map Sheet Covering South Australia

Olary SI54-02 is a digital topographic map from the AUSTopo series produced by Geoscience Australia. It provides coverage at a 1:250,000 scale, where 1 cm represents 2.5 km on the ground, and is part of a national series comprising 516 standard maps. The map contains natural and constructed features including infrastructure, vegetation, hydrography, and 50-meter contours.

Use Cases

• Extract road and rail infrastructure features for regional transportation network analysis.
• Analyze hydrography and 50-meter contour intervals for watershed modeling and terrain assessment.
• Identify vegetation coverage and administrative boundaries for land-use planning studies.
• Georeference map features using its GDA94/GDA2020 datum and UTM projection for spatial integration.

Strengths

• Part of a standardized national series covering the entire Australian continent with 516 maps.
• Provides detailed topographic features at a large 1:250,000 scale, the largest covering the whole continent.
• Contains multiple coordinate references including GDA94, GDA2020, and AHD datums for accurate geospatial work.

Limitations

• Data is provided only in PDF format, requiring feature extraction for analytical use.
• Map may contain information from surrounding sheets, potentially complicating precise boundary analysis.
• Specific data volume, row count, and column structure for underlying features are not disclosed.
