ALS DTM: Austrian 1-Meter Digital Terrain Elevation Grid

One of 55 tiles covering Austria, this 1-meter resolution digital terrain model describes the bare earth surface. The ALS DTM height grid was recorded using airborne laser scanning technologies and is a cooperation product of Austrian federal and state spatial data providers. Data is georeferenced in European reference systems and represents the natural soil without vegetation.

Use Cases

• Terrain analysis and slope calculation based on the 1-meter elevation grid.
• Hydrological modeling for flood risk assessment based on the bare earth surface data.
• Infrastructure and construction planning based on high-resolution terrain elevation.
• Environmental change detection and monitoring based on the digital terrain model product group.

Strengths

• 1-meter spatial resolution provides detailed terrain information.
• Data is part of a 55-tile mosaic covering the entire territory of Austria.
• Explicitly models the bare earth surface without vegetation using airborne laser scanning.

Limitations

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