Wet Tropics Bioregion Contours from 1:50,000 Scale Topographic Maps

Geoscience Australia's 1:50,000 scale National Topographic Map Series provides line and point features depicting contours across the Wet Tropics Bioregion. The dataset has a horizontal accuracy where 90% of well-defined detail is within +/- 25 meters of its true position. Data is reproduced with permission of the Wet Tropics Management Authority and was prepared for the eAtlas.

Use Cases

• Generate digital elevation models based on the described contour line features.
• Analyze watersheds and drainage patterns based on the topographic contour data.
• Create topographic base maps for environmental planning based on the 1:50,000 scale source.
• Model slope and aspect for ecological studies based on the contour line features.

Strengths

• Horizontal accuracy is specified as 90% of well-defined detail within +/- 25 meters.
• Derived from the authoritative Geoscience Australia 1:50,000 scale National Topographic Map Series.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The metadata record is noted as non-authoritative; users must contact the Wet Tropics Management Authority for an authoritative record.
• Row count is unknown, which may limit suitability assessment.
