Austrian Digital Terrain Elevation Model Grid at 1-Meter Resolution

Austria is covered by a digital terrain elevation model (DGM) describing the earth's natural surface without vegetation. The data consists of a regular grid of points spaced 1 meter apart, georeferenced in European coordinate systems and captured via airborne laser scanning. This tile is one of 55 produced through cooperation between Austrian federal and state spatial data providers.

Use Cases

• Modeling hydrological flow and watershed delineation based on the bare-earth elevation surface.
• Planning infrastructure projects using the high-resolution terrain model for slope and visibility analysis.
• Conducting environmental impact assessments by analyzing changes in the natural landform.
• Creating base layers for 3D landscape visualization and simulation based on the 1-meter grid.

Strengths

• Data is captured via airborne laser scanning, a precise remote sensing technology.
• The elevation grid has a high spatial resolution of 1 meter.
• The dataset is one tile in a complete, 55-tile coverage of Austria.
• Data is licensed under CC-BY-4.0, permitting sharing and adaptation.

Limitations

• The specific row count and file size are unknown, complicating suitability assessment.
• Column-level documentation is absent; data structure must be inferred from the TIFF format after download.
• The last update date is unknown; data freshness is unverified beyond the stated cut-off date.
