Coordinate systems in United Arab Emirates: quick reference
Legacy mapping in the UAE sits on the Nahrwan 1967 datum (EPSG:4270) — named after the Nahrwan origin station in Iraq and spread through the Gulf by petroleum survey work — with UTM zones 39 (EPSG:27039) and 40 (EPSG:27040). Before it, the Trucial Coast datum TC(1948) (EPSG:4303) underpinned the earliest UAE surveys.
The country splits between two UTM zones at longitude 54°E: Abu Dhabi city sits almost on the boundary, while Dubai and the northern emirates fall in zone 40. Dubai adds its own layer: Dubai Municipality works on the Dubai Local TM projection on WGS84 (EPSG:3997), so deliverables inside Dubai are often requested in that grid rather than UTM.
Enter your coordinates below — the tool opens on an Abu Dhabi sample point, lists the UAE systems first, and returns the value in every system that covers the point, each with its accuracy badge.
| EPSG | System | Accuracy |
|---|---|---|
| 4270 | Nahrwan 1967(geographic) | ±0.6 m |
| 27039 | Nahrwan 1967 / UTM zone 39N(projected grid) | ±0.8 m |
| 27040 | Nahrwan 1967 / UTM zone 40N(projected grid) | ±0.6 m |
| 4303 | TC(1948)(geographic) | ±0.1 m |
| 30340 | TC(1948) / UTM zone 40N(projected grid) | ±0.1 m |
The tool covers 9 systems relevant to United Arab Emirates (national systems plus the WGS84 UTM zones) — the table above lists only the key ones.
FAQ
- Which coordinate system does the UAE use?
- Legacy sheets sit on Nahrwan 1967 with UTM zone 39 or 40; the oldest surveys used TC(1948). Modern work observes on WGS84, and Dubai uses its own Dubai Local TM projection (EPSG:3997).
- What is the Nahrwan 1967 datum?
- A geodetic datum whose origin station lies at Nahrwan near Baghdad; petroleum survey work carried it through the Gulf and it became the basis of legacy UAE mapping (EPSG:4270 with zones 27039 and 27040).
- Which UTM zone is Dubai in, and what is Dubai Local TM?
- Dubai (about 55.3°E) falls in UTM zone 40. Dubai Municipality, however, adopted a local Transverse Mercator on WGS84 — Dubai Local TM (EPSG:3997) — with a central meridian through Dubai; most deliverables inside the emirate are requested in that grid.
- Why does GPS disagree with an old Nahrwan sheet?
- GPS observes on WGS84 while the sheet sits on Nahrwan 1967; the datums differ by tens of metres in the UAE. The tool applies the published EPSG shift automatically.
