EPSG 4921 Code: Understanding the geodetic parameter dataset
When working with geospatial data, it is essential to have a standardized system for referencing and representing locations on the Earth's surface. EPSG (European Petroleum Survey Group) codes are a popular geodetic parameter dataset that defines coordinate systems, datums, projections, and other geodetic parameters. These codes ensure interoperability and accuracy of geospatial applications and data exchange.
The EPSG dataset is maintained and regularly updated by the IOGP (International Association of Oil & Gas Producers) and the IAG (International Association of Geodesy). It contains a rich collection of CRSs (Coordinate Reference Systems), which determine and measure coordinates on the Earth's surface.
Each EPSG code corresponds to a specific CRS, and provides detailed information about its properties, including the datum, ellipsoid, projection method, units of measure, and coordinate transformation parameters. EPSG 4921 Code ensure consistent definitions and referencing of coordinate systems across different software tools, databases, and applications. They provide a standardized framework for exchanging geospatial data, facilitating seamless interoperability and accurate spatial analysis.
