Distinctive Land Surface Points for New South Wales Physiography

Distinctive Land Surface Point is a point feature class defining discrete land surface features like reefs. The dataset is part of the NSW Foundation Spatial Data Framework, published by Spatial Services, a business unit of the Department of Customer Service NSW. Initial publication was on 07/02/2020, with data currency listed as 01/01/3000.

Use Cases

• Identify and map reef locations from the 'Reef' feature class for coastal hazard modeling.
• Analyze the spatial distribution of Distinctive Land Surface (DLS) points for geomorphological research.
• Integrate DLS point features with other NSW Foundation Spatial Data Framework themes like transport or water for comprehensive spatial analysis.
• Validate the positional accuracy of new spatial data against this foundational dataset.

Strengths

• Dataset maintains positional alignment with multiple themes from the NSW Foundation Spatial Data Framework.
• Features were digitized from cadastral mapping at scales ranging from 1:500 to 1:250,000, providing varied detail.

Limitations

• Positional accuracy varies significantly based on the source map scale, from 1:500 to 1:250,000.
• The service is scheduled for retirement and uses the GDA94 spatial reference, which may cause misalignment in GDA2020 environments.
