EPSG:4326 Coordinate Reference System

Geographic CRS · WGS 84 datum · angular units in degrees · coordinates are entered longitude then latitude in this tool. Inspect EPSG:4326 as included in the GeoCAD Bridge CRS catalog. Use the converter below to transform test coordinates to another bundled CRS. For authoritative operation metadata and datum accuracy, consult the EPSG Registry; this page reports no accuracy unsupported by bundled data.

Transforms run in your browser. The basemap provider receives tile requests for the visible map area.

Transformation uses the bundled proj4js definitions. No authoritative accuracy metadata or datum grids are available here.

How coordinate transformation works

The app converts through the source and target projection definitions bundled with the application. Datum changes may require parameters or grids that are not available; this page does not claim unsupported accuracy.

CRS details for engineering use

Review the CRS type, projection method, datum, units, axis order and area of use before mixing CAD, GIS and survey data. EPSG pages in GeoCAD Bridge link directly to transformation tools so test coordinates can be checked before production delivery.

Example coordinates

A WGS 84 point at longitude 0.0°, latitude 0.0° (inside the area of use) has these coordinates in EPSG:4326:

Computed with PROJ using the EPSG default operation: axis order change (2D) + Null geographic offset from WGS 84 to WGS 84 + axis order change (2D).

PROJ string

A PROJ string cannot carry every EPSG detail (axis order, datum ensemble, transformations). Prefer WKT2 or the EPSG code itself.

Proj4js definition used by the converter

+proj=longlat +datum=WGS84 +no_defs

No datum shift is needed: this CRS is on WGS 84 or a datum Proj4js treats as equivalent at the metre level.

FAQ

What is EPSG:4326?

EPSG:4326 (WGS 84) is a geographic 2D coordinate reference system on the World Geodetic System 1984 ensemble datum with coordinates in degrees. Area of use: World. The datum is an ensemble with about 2.0 m accuracy, so precise work should name a specific realization.

Where can EPSG:4326 be used?

Its area of use is: World.

What is the axis order of EPSG:4326?

By the EPSG definition: Geodetic latitude, Geodetic longitude. Many GIS formats such as GeoJSON and KML store longitude first instead.
