EPSG:3997 — WGS 84 / Dubai Local TM

Source: EPSG Dataset via PROJ 9.5.1 · Updated 2026-10-05

Summary

EPSG:3997 (WGS 84 / Dubai Local TM) is a projected coordinate reference system on the World Geodetic System 1984 ensemble datum using the Transverse Mercator method, with coordinates in metres. Area of use: United Arab Emirates (UAE) - Dubai municipality. The datum is an ensemble with about 2.0 m accuracy, so precise work should name a specific realization.

Type: projected
Datum: World Geodetic System 1984 ensemble
Units: metre

Projection parameters

Transverse Mercator parameters.
Parameter	Value	Unit
Latitude of natural origin	0	degree
Longitude of natural origin	55.33333333	degree
Scale factor at natural origin	1	unity
False easting	500,000	metre
False northing	0	metre

Example coordinates

A WGS 84 point at longitude 55.195°, latitude 25.095° (inside the area of use) has these coordinates in EPSG:3997:

Computed with PROJ using the EPSG default operation: axis order change (2D) + Dubai Local Transverse Mercator.
Axis	Value	Unit
E	486,045.986	m
N	2,776,584.805	m

At this point the projection scale factor is 1.00000240 and the grid convergence is -0.058670°.

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

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:3997?

Where can EPSG:3997 be used?

Its area of use is: United Arab Emirates (UAE) - Dubai municipality.

Is EPSG:3997 in metres or degrees?

EPSG:3997 is projected, so coordinates are easting and northing in metres, not degrees.

How do I convert EPSG:3997 to latitude and longitude?

Transform from EPSG:3997 to EPSG:4326 (WGS 84). In GeoCAD Bridge open the coordinate converter with EPSG:3997 preselected, enter easting and northing, and choose WGS 84 as the target.
