ALS DTM: Austrian Digital Terrain Elevation Model 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, recorded via airborne laser scanning. This is one of 55 tiles covering the territory of Austria.

Use Cases

• Modeling flood risk based on the 1-meter resolution terrain surface.
• Planning construction or infrastructure projects based on bare-earth elevation data.
• Conducting geomorphological analysis based on the detailed digital terrain model.
• Creating base layers for 3D landscape visualization based on the height grid.

Strengths

• Data is provided in a 1-meter resolution grid, offering high spatial detail.
• The dataset is part of a systematic 55-tile collection covering the entire territory 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.
• Data may reflect geographic bias inherent to eu_open_data, focusing solely on Austria.
