As DTM CRS3035RES50000mN2700000E4400000 elevation grid 1 m cut-off date 15.9.2022

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 covering the national territory. It is a cooperation product of Austrian federal and state spatial data providers, with a stated cut-off date of September 15, 2022.

Use Cases

• Modeling water flow and flood risk based on the high-resolution bare-earth elevation data.
• Planning linear infrastructure like roads or power lines using the detailed terrain surface.
• Conducting visibility and line-of-sight analyses for telecommunications or defense applications.
• Creating base layers for 3D landscape visualization and simulation.

Strengths

• High 1-meter spatial resolution for detailed terrain representation.
• Covers the entire territory of Austria as part of a 55-tile mosaic.
• Explicitly models the bare earth surface, excluding vegetation, which is useful for hydrological and geological studies.
• Uses airborne laser scanning, a direct measurement technology for elevation.

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 description does not specify vertical accuracy or point density metrics for the LiDAR data.
