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

55 tiles of a 1-meter resolution digital terrain model (DTM) cover the territory of Austria. The ALS DTM elevation grid was recorded using airborne laser scanning technologies and describes the earth's natural surface without vegetation. This is a cooperation product of Austrian federal and state spatial data providers, with a data cut-off date of September 15, 2019.

Use Cases

• Model water flow and flood risk based on the high-resolution terrain elevation data.
• Plan infrastructure projects by analyzing ground surface topography from the digital terrain model.
• Conduct environmental impact assessments using the bare-earth elevation data to study natural landscapes.
• Create 3D visualizations and maps from the georeferenced height grid data.

Strengths

• Data has a high spatial resolution of 1 meter per grid cell.
• The dataset consists of 55 tiles providing complete coverage 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 beyond the stated cut-off date.
• Row count and total file size are unknown, which may limit suitability assessment.
