Two-part geodetic product from Cooperation OGD Österreich and Wikimedia Österreich enables one-step transformation of ellipsoidal heights to physical heights. The data is suitable for adjusting heights from laser scanning and GNSS measurements to conform with Austrian map systems. It is available in CSV and GEOTIFF formats under a CC-BY-4.0 license.
Use Cases
- Transform ellipsoidal heights from laser scanning data to physical heights based on the described one-step transformation process.
- Correct usage heights in point maps to achieve conformity with GNSS-derived heights using the provided correction values.
- Adjust heights generated from the height grid plus geoid to match the heights of official positioning points.
Strengths
- Enables a one-step transformation between two major geodetic reference systems (ETRS89/GRS80 and MGI).
- Includes correction values to align map point heights with GNSS measurements.
- Available in multiple common geospatial formats (CSV and GEOTIFF).
Limitations
- Row count and data size are unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
- Last update date is unknown; freshness unverified.
