NSW Elevation and Depth Theme: Digital Terrain Model

Spatial Services provides a statewide digital elevation and depth dataset for New South Wales, Australia. The dataset is available as a 5-meter resolution Digital Elevation Model (DEM) and is accessible via multiple web services and APIs. This GDA94-aligned service is scheduled for retirement, with users directed to transition to a new GDA2020-compliant service.

Use Cases

• Terrain analysis and slope modeling based on the 5-meter DEM resolution.
• Hydrological modeling for flood risk assessment using elevation and depth data.
• Infrastructure planning and line-of-sight analysis for telecommunications or construction.
• Environmental impact studies requiring detailed topographic information.

Strengths

• Provides a specific 5-meter resolution DEM, indicating a detailed level of topographic detail.
• Offers multiple access methods including a REST API, web services, and the ELVIS platform, suggesting broad programmatic availability.
• Managed by an authoritative government organization, Spatial Services (DCS).

Limitations

• The core service is deprecated and scheduled for retirement, indicating it is not for new projects.
• The dataset uses the GDA94/WGS84 spatial reference, which may cause misalignment in modern GDA2020 coordinate environments.
• Key metadata such as column names, row count, and specific license terms are not provided in the input.
