Vicmap Position is a test dataset for high-accuracy coordinate transformation and conversion in and around Victoria, Australia. It is provided by the Department of Energy, Environment and Climate Action and was last updated on 2026-04 08. The data can be used to validate software performing transformations between the Australian Geodetic Datum 1966 (AGD66) and the Geocentric Datum of Australia 1994 (GDA94).
Use Cases
- Validate software implementations of the official ICSM high-accuracy 7-parameter/distortion model transformation process.
- Test conversions between geographical coordinates (latitude/longitude) for AGD66 and GDA94.
- Test conversions between Universal Transverse Mercator (UTM) grid coordinates for AMG66 and MGA94.
- Test conversions for custom Lambert conformal conic projection coordinates relating to Vicgrid66 and Vicgrid94 specifications.
Strengths
- Focuses on high-accuracy transformations using the official ICSM model and NTv2 grid file format.
- Covers multiple coordinate types: geographicals, UTM, and custom Lambert projections.
- Released under a permissive CC-BY-4.0 license.
- Data is provided in multiple common GIS file formats: MIF, SHP, TAB, GDB.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
