Brisbane Airport Obstacle Limitation Surface Contours

Brisbane City Council provides Obstacle Limitation Surfaces (OLS) data for airport environs, derived from the City Plan 2014 overlay. The dataset includes sub-categories for approach, conical, horizontal, and transitional surface boundaries and contours. It is maintained by Brisbane City Council and updated as part of the city planning process.

Use Cases

• Analyze approach and departure limitation surface boundaries to model aircraft glide paths.
• Map conical limitation surface contours for urban development height compliance checks near airports.
• Use transitional surface sub-category data to assess building permit applications within airport zones.
• Cross-reference horizontal limitation surface boundaries with other planning datasets for infrastructure projects.

Strengths

• Data is officially sourced and licensed from Brisbane Airport Corporation (BAC).
• Part of the regularly updated Brisbane City Plan 2014 framework.
• Includes four defined OLS sub-categories for specific aviation safety analyses.

Limitations

• No quantitative details on spatial extent, row count, or resolution are provided.
• Primary use is restricted to planning and development in Brisbane; other uses are not authorized.
• Understanding requires cross-referencing with the separate reference dataset and City Plan document.
