Austrian Digital Terrain Elevation Model: 1-Meter Grid from Airborne Laser Scanning

One tile from a 55-tile ALS DTM height grid covering Austria, describing the earth's surface without vegetation. The data is a regular 1-meter grid georeferenced in European coordinate systems, recorded via airborne laser scanning technologies. This product is a cooperation between Austrian federal and state spatial data providers.

Use Cases

• Model water runoff and flood risk based on the described bare-earth terrain surface.
• Plan infrastructure projects using the high-resolution 1-meter ground elevation data.
• Analyze topographic features for environmental studies based on the digital terrain model.

Strengths

• Provides a 1-meter resolution grid for detailed terrain analysis.
• Covers the full territory of Austria as part of a 55-tile product.
• Explicitly models the natural soil surface without vegetation.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
• Row count is unknown, which may limit suitability assessment.
