EOV to WGS84 Converter
About EOV Coordinate System
EOV is Hungary's national unified projection coordinate system, used for GIS, mapping, and cadastral surveys.
EOV was introduced in 1975 to replace earlier Hungarian coordinate systems.
EOV is the standard coordinate system for all official Hungarian mapping, land administration, and urban planning.
EOV is a plane coordinate system specific to Hungary, using easting and northing values in meters.
EOV uses a modified Gauss-Kruger projection with a central meridian at 19 deg E.
About WGS84 Coordinate System
WGS84 (World Geodetic System 1984) is the global standard geodetic reference system used by GPS. It defines an Earth-centered, Earth-fixed coordinate system and geodetic datum.
Developed by the U.S. Department of Defense in 1984, WGS84 has undergone several refinements (WGS84(G730), WGS84(G873), WGS84(G1150), WGS84(G1762)) to improve accuracy through GPS satellite observations.
WGS84 is the default coordinate system for GPS receivers worldwide. It is used in aviation, maritime navigation, Google Maps, OpenStreetMap, GIS applications, and scientific research.
WGS84 is the native coordinate system of the Global Positioning System (GPS), ensuring direct compatibility with all GPS receivers and satellite navigation systems worldwide.
As the most widely adopted geodetic datum, WGS84 provides a consistent global reference frame for mapping, surveying, and geospatial data exchange across international boundaries.
With continuous refinements, WGS84 achieves centimeter-level accuracy globally, making it suitable for high-precision applications like surveying, drone navigation, and scientific research.
EOV → WGS84 Conversion Guide
// EOV → WGS84 (Hungarian EOV projection)
// EOV uses a modified Gauss-Krüger projection
// Central meridian: 19°E
// Bessel 1841 ellipsoid: a = 6377397.155m, 1/f = 299.1528128
// The projection converts between geographic coordinates
// (latitude, longitude) and plane coordinates (X, Y in meters)
// using the Gauss-Krüger projection formulas adapted for Hungary
// EOV planar coordinates:
// Easting (X): 650,000m at central meridian
// Northing (Y): 200,000m at originThe Hungarian EOV system uses a modified Gauss-Kruger projection optimized for Hungary. It uses the Bessel 1841 ellipsoid with a central meridian at 19 degrees E.
