Ipswich City Contour Map Derived from 2019 LiDAR

Contour lines at a 1-meter vertical interval cover the entire Ipswich City Council authority area. The data was compiled by the Ipswich City Council from a 2019 Airborne Laser Scanning (LiDAR) project. It provides a detailed topographic model of the region.

Use Cases

• Generate digital elevation models (DEMs) from the 1-meter contour interval for hydrological analysis.
• Analyze slope stability and terrain roughness using the contour line geometry for engineering projects.
• Integrate contour data with other geospatial layers via the provided WFS/WMS services for comprehensive land use planning.
• Train machine learning models for automated feature extraction from LiDAR-derived topographic data.

Strengths

• Data covers the entire administrative area of Ipswich City Council.
• Derived from a dedicated 2019 Airborne Laser Scanning (LiDAR) project, indicating a systematic collection method.
• Available in multiple interoperable geospatial formats including GeoJSON, SHP, and WFS.

Limitations

• Specific spatial resolution (point density) and vertical accuracy metrics from the LiDAR survey are not provided.
• The dataset is a single snapshot from 2019 and may not reflect recent terrain changes.
• The total file size and data volume are unknown, which complicates download and storage planning.
