Broad Geology of the Wet Tropics of Queensland, 2015

The Broad Geology of Wet Tropics of Queensland - 2015 (WTMA) dataset combines high-resolution geology mapping from the Wet Tropics Bioregion with state-wide Regional Ecosystem data to provide continuous geological coverage. It was created by the Australian Ocean Data Network and resolves gaps in the original mapping by filling in cleared and regrowth areas. The dataset classifies geology into 12 landzone categories, including Saline Alluvium, Basalts, and Granites.

Use Cases

• Modeling soil erosion risk based on broad geological classifications like Alluvium and Basalts.
• Planning conservation corridors by analyzing geological continuity between the Wet Tropics and adjoining bioregions.
• Assessing land suitability for agriculture or development using the combined Landzone geology classifications.

Strengths

• Integrates two complementary data sources to fill gaps in original high-resolution mapping.
• Provides a defined classification scheme with 12 geology landzone categories.
• Extends coverage beyond the Wet Tropics Bioregion for regional continuity.

Limitations

• Geology classifications are broader than the original high-resolution source due to grouping for compatibility.
• Description metadata is limited; actual data quality requires manual inspection after download.
• Row count is unknown, which may limit suitability assessment.

Provenance

Source

Combination of the 'Geology of the Wet Tropics Bioregion (WTMA)' dataset and Queensland Government's Regional Ecosystem mapping.

Collection Method

Geology information was extracted from Pre-clearing regional ecosystems mapping, which was developed from aerial photography and field surveys of vegetation communities.

Time Range

Snapshot from 2015, based on source data from 1960-1993 aerial photography and subsequent surveys.

Geography

Wet Tropics of Queensland and surrounding areas from Ayr to north of Cooktown, Australia, including adjoining bioregions.
