As DTM CRS3035RES50000mN2600000E4350000 elevation grid 1 m cut-off date 15.9.2021

A 1-meter resolution digital terrain elevation model (DTM) for Austria, representing the bare earth surface without vegetation. The data was captured using airborne laser scanning (ALS) technologies and is one of 55 tiles that collectively cover the country's territory. The product is a cooperation between Austrian federal and state spatial data providers, with a stated cut-off date of September 15, 2021.

Use Cases

• Modeling hydrological flow and flood risk based on the high-resolution bare-earth elevation data.
• Planning infrastructure projects like roads or power lines using the detailed terrain surface model.
• Analyzing landscape morphology and geomorphological features based on the 1-meter grid.
• Creating base layers for 3D visualizations and simulations of the natural terrain.

Strengths

• High spatial resolution of 1 meter for detailed terrain representation.
• Covers the entire territory of Austria through a tiled system of 55 files.
• Explicitly models the bare earth surface, excluding vegetation, which is suitable for terrain analysis.
• Data is georeferenced in European coordinate reference systems for interoperability.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total file size are unknown, which may limit suitability assessment.
• The last update date is unknown; freshness beyond the 2021 cut-off is unverified.
