Wimmera Region Elevation Contours and Digital Terrain Model

Elevation data for the Wimmera CMA region in Australia, derived from a 2004 lidar survey. The dataset includes 1.0-meter contour coverage across the entire region and higher-resolution 0.5-meter contours along the Wimmera River Trench. It was created and provided by the Wimmera Catchment Management Authority.

Use Cases

• Generate high-resolution 0.5m contour lines along the Wimmera River Trench for detailed flood modeling.
• Create a Digital Elevation Model (DEM) from the lidar point cloud data for regional terrain analysis.
• Analyze watershed boundaries and drainage patterns using the 1.0m contour coverage across the Wimmera CMA region.
• Integrate contour tile data with other geospatial layers for land use planning and environmental impact assessment.

Strengths

• High-resolution 0.5m contour data available for the Wimmera River Trench.
• Full 1.0m contour coverage across the entire Wimmera CMA region.
• Underlying lidar point cloud data is available upon request for custom analysis.

Limitations

• Primary data source is from a 2004 survey, which may not reflect recent terrain changes.
• Specific row counts, file sizes, and detailed column metadata are not provided.
