As DTM CRS3035RES50000mN2550000E4650000 elevation grid 1 m cut-off date 15.9.2022

The ALS DTM height grid is a digital terrain elevation model product describing Austria's bare-earth surface. It is a 1-meter resolution grid of elevation points, recorded via airborne laser scanning and georeferenced in European coordinate systems. This specific file is one of 55 tiles that collectively cover the entire territory of Austria, produced through a cooperation of Austrian federal and state spatial data providers.

Use Cases

• Modeling water flow and flood risk based on the high-resolution bare-earth elevation data.
• Planning infrastructure projects by analyzing terrain slope and features from the digital terrain model.
• Conducting environmental impact studies using the detailed, vegetation-free representation of the ground surface.
• Creating base layers for 3D landscape visualizations and simulations based on the 1-meter grid data.

Strengths

• Data has a high spatial resolution of 1 meter per grid cell.
• The dataset is part of a complete, tiled coverage of Austria consisting of 55 files.
• It represents the bare-earth surface, having removed vegetation, which is suitable for terrain analysis.

Limitations

• The specific row count and total file size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The last update date is unknown; freshness is unverified beyond the stated cut-off date of 15 September 2022.
