ALS DTM: Austrian Digital Terrain Elevation Model at 1-Meter Resolution

An Airborne Laser Scanning (ALS) Digital Terrain Model (DTM) elevation grid for Austria. The data describes the natural earth's surface without vegetation, represented as points in a regular 1-meter grid georeferenced in European coordinate systems. This tile is one of 55 that collectively cover the entire territory of Austria, produced through cooperation between Austrian federal and state spatial data providers.

Use Cases

• Modeling hydrological flow and flood risk based on the 1-meter resolution terrain surface.
• Planning infrastructure projects by analyzing slope and elevation changes described in the DTM.
• Conducting environmental impact assessments using the bare-earth surface data captured by laser scanning.

Strengths

• Data has a high spatial resolution of 1 meter per grid point.
• The dataset is part of a complete, tiled coverage of Austria consisting of 55 files.
• Data is georeferenced using standardized European coordinate reference systems.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
• The specific cut-off date for this tile (15.9.2022) may not reflect the latest terrain changes.
