Distinctive Land Surface Points for New South Wales, Australia

Distinctive Land Surface (DLS) Point is a point feature class defining features of discrete extent, such as reefs. The dataset is part of the NSW Physiography Category within the Foundation Spatial Data Framework (FSDF) and has been updated to the GDA2020 national spatial standard. It is provided by Spatial Services, a business unit of the Department of Customer Service NSW.

Use Cases

• Environmental impact assessment based on the location of distinctive land surface features like reefs.
• Coastal zone management and planning based on the defined point features.
• Cartographic base layer creation for thematic maps based on physiographic categories.
• Data integration and alignment with other NSW FSDF themes like transport and water.

Strengths

• Aligned with the national GDA2020 spatial standard, improving accuracy and compatibility.
• Maintains a positional relationship with multiple NSW FSDF themes, including transport and water.
• Positional accuracy is defined per map scale, ranging from 0.25m at 1:500 scale to 50m at 1:100,000 scale.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data was captured from cadastral mapping at varying scales (1:500 to 1:250,000), leading to inherent accuracy differences.
