Brisbane City Council Contour Lines from 2002 in GDA94/MGA56

Contour lines mapped over the Brisbane City Council local government area in 2002 use the Geocentric Datum of Australia 1994 (GDA94) and are projected in Zone 56 of the Map Grid of Australia (MGA56). The dataset, provided by Brisbane City Council's open data platform, offers download links for predefined grid envelopes in DWG format or via a JSON API for custom coordinate extraction. Data and resources sections contain further information including links to additional contours feature layers.

Use Cases

• Generate elevation models for flood risk assessment based on the contour line data.
• Plan construction and earthworks projects using the topographic detail of the Brisbane area.
• Conduct terrain analysis for environmental studies based on the 2002 contour mapping.
• Create custom map overlays for specific project areas using the JSON API for custom coordinate envelopes.

Strengths

• Data uses a defined geospatial standard (Geocentric Datum of Australia 1994 / Map Grid of Australia Zone 56).
• Offers flexible download options including a JSON API for extracting contour lines within custom coordinate envelopes.
• Dataset is associated with additional contours feature layers as noted in the resources section.

Limitations

• Data is from a single year (2002), which may not reflect current terrain conditions.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
