As DTM CRS3035RES50000mN2850000E4750000 elevation grid 1 m cut-off date 15.9.2019

One of 55 tiles covering Austria, this 1-meter resolution digital terrain model describes the bare earth surface without vegetation. The ALS DTM elevation grid was produced using Airborne Laser Scanning technologies by Austrian federal and state spatial data providers. Data is georeferenced in European reference systems and has a specified cut-off date of September 15, 2019.

Use Cases

• Modeling hydrological flow and watersheds based on the 1-meter bare-earth elevation data.
• Planning infrastructure projects requiring precise terrain contours and slope calculations.
• Conducting environmental impact assessments that rely on accurate ground surface models.
• Creating base layers for 3D landscape visualization and simulation.

Strengths

• High spatial resolution of 1 meter for detailed terrain representation.
• Explicitly models the bare earth surface, excluding vegetation, which is critical for certain analyses.
• Covers the entire territory of Austria as part of a 55-tile mosaic.
• Data collection method (Airborne Laser Scanning) is specified, suggesting a direct measurement source.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified beyond the 2019 cut-off.
• Row count and total file size are unknown, which may limit suitability assessment.
