As DTM CRS3035RES50000mN2600000E4350000: Austrian 1-Meter Digital Terrain Elevation Grid

A 1-meter resolution digital terrain elevation model (DTM) tile for Austria, with a data cut-off date of 15 September 2022. The grid describes the earth's natural surface without vegetation, recorded using airborne laser scanning technologies. It is one of 55 tiles produced through cooperation between Austrian federal and state spatial data providers.

Use Cases

• Modeling water flow and flood risk based on the 1-meter resolution terrain surface.
• Planning construction and infrastructure projects based on high-resolution bare-earth elevation data.
• Conducting environmental impact studies based on the detailed representation of the natural soil surface.
• Creating base layers for 3D landscape visualizations based on the georeferenced elevation grid.

Strengths

• High spatial resolution of 1 meter for detailed terrain representation.
• Data is georeferenced in European reference systems for positional accuracy.
• Covers the territory of Austria as part of a 55-tile mosaic.

Limitations

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