As DTM CRS3035RES50000mN2650000E4250000: Austrian 1-Meter Digital Terrain Elevation Grid

One of 55 tiles covering Austria, this 1-meter resolution digital terrain model describes the bare earth surface. The ALS DTM elevation grid was recorded using airborne laser scanning technologies and is a cooperation product of Austrian federal and state spatial data providers. Data is georeferenced in European reference systems and has a stated cut-off date of September 15, 2021.

Use Cases

• Modeling hydrological flow based on the 1-meter bare earth elevation grid.
• Planning infrastructure projects using the high-resolution terrain surface data.
• Conducting environmental impact assessments based on the detailed digital terrain model.
• Creating 3D visualizations of the Austrian landscape based on the georeferenced elevation data.

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.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
