Austrian Digital Terrain Elevation Model Grid at 1-Meter Resolution

The ALS DTM height grid is a product of the Austrian federal and state spatial data providers. It describes the earth's natural surface in a regular 1-meter grid, derived from airborne laser scanning technologies. This dataset is one of 55 tiles that together cover the territory of Austria.

Use Cases

• Model water flow and flood risk based on the detailed bare-earth elevation data.
• Plan construction and civil engineering projects based on accurate terrain height information.
• Conduct environmental impact studies based on the high-resolution ground surface model.
• Create base maps for GIS applications based on the standardized digital terrain elevation model.

Strengths

• Data is provided at a high 1-meter spatial resolution.
• The dataset is part of a larger, standardized product group covering all of Austria.
• Data is georeferenced in European reference systems for positional accuracy.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
• The description does not specify the exact temporal coverage of the data collection.
