As DTM CRS3035RES50000mN2700000E4250000 elevation grid 1 m cut-off date 15.9.2021

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 georeferenced height points created from airborne laser scanning data by Austrian federal and state spatial data providers. This file is one of 55 tiles that together cover the entire territory of Austria, with a data cut-off date of September 15, 2021.

Use Cases

• Modeling water flow and flood risk based on the detailed 1-meter bare-earth elevation data.
• Planning construction and infrastructure projects using the high-resolution terrain surface model.
• Conducting environmental impact assessments for forestry or agriculture based on terrain characteristics.
• Creating base layers for 3D landscape visualization and simulation based on the digital terrain model.

Strengths

• The dataset provides a high-resolution 1-meter grid for detailed terrain analysis.
• It is part of a complete, tiled coverage of Austria consisting of 55 files.
• Data is georeferenced in European reference systems for positional accuracy.
• The model specifically represents the bare-earth surface, excluding vegetation.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale processing.
• Last update date is unknown; freshness unverified beyond the stated cut-off date.
