As DTM CRS3035RES50000mN2700000E4550000 elevation grid 1 m cut-off date 15.9.2021

A digital terrain elevation model (DGM) grid of Austria derived from airborne laser scanning (ALS) data. The dataset describes the earth's natural surface without vegetation, with points arranged in a regular 1-meter grid georeferenced in European coordinate systems. This is one of 55 tiles produced through cooperation between Austrian federal and state spatial data providers, with a stated cut-off date of September 15, 2021.

Use Cases

• Modeling water flow and flood risk based on the high-resolution bare-earth elevation data.
• Planning infrastructure projects like roads or power lines using the detailed terrain surface.
• Conducting environmental impact assessments for land development based on the natural soil elevation.
• Creating base layers for 3D landscape visualization and simulation based on the 1-meter grid.

Strengths

• Data has a high spatial resolution of 1 meter per grid point.
• The dataset is part of a larger, complete coverage of Austria consisting of 55 tiles.
• Data collection method is specified as airborne laser scanning (ALS) technology.
• The data uses standardized European reference systems for georeferencing.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total dataset size are unknown, which may limit suitability assessment.
• The last update date for the platform entry is unknown; freshness unverified.
