NSW Elevation and Depth Theme: 5m Digital Elevation Model

Spatial Services provides elevation and depth data for New South Wales, Australia, including a 5-meter Digital Elevation Model (DEM). The dataset is a foundational geospatial layer for terrain analysis, hydrology, and infrastructure planning. However, the primary GDA94 service is scheduled for retirement, with users directed to transition to a new GDA2020 service.

Use Cases

• Flood risk modeling based on detailed 5m elevation data.
• Terrain analysis for infrastructure and construction planning using the DEM.
• Hydrological studies leveraging elevation and depth data for watershed delineation.
• Transitioning geospatial applications from the GDA94 to the GDA2020 coordinate reference system.

Strengths

• Provides a detailed 5-meter resolution Digital Elevation Model for NSW.
• Managed by an authoritative source, Spatial Services (DCS).
• Offers multiple access methods including API, data export, and a dedicated platform (ELVIS).

Limitations

• The primary service is deprecated and scheduled for retirement, requiring users to migrate.
• The GDA94 spatial reference may cause misalignments in GDA2020 environments.
• Key metadata such as row count, file size, license, and specific column names are unavailable.
