Coordinate systems in Oman: quick reference
Surveying in Oman grew out of the petroleum sector: the Fahud datum (EPSG:4232) — named after the origin station at the Fahud oil field — underpinned Petroleum Development Oman mapping, and was superseded by PSD93 (EPSG:4134), the “Petroleum Survey Datum 1993” that became the de-facto standard for oil sheets and projects, used with UTM zones (e.g. EPSG:3440 for zone 40 covering Muscat).
More recently the Sultanate adopted a national frame tied to the global reference frames: ONGD14 (EPSG:7373) and then ONGD17 (EPSG:9294) for new geodetic work. The country spans three UTM zones, 39 to 41 — Muscat sits in zone 40, Dhofar in the west touches 39, and the eastern offshore areas reach 41.
Enter your coordinates below — the converter opens on a Muscat sample point and lists the Omani systems first, each with an honest accuracy badge.
| EPSG | System | Accuracy |
|---|---|---|
| 4134 | PSD93(geographic) | ±0.1 m |
| 3440 | PSD93 / UTM zone 40N(projected grid) | ±0.1 m |
| 4232 | Fahud(geographic) | ±0.1 m |
| 23240 | Fahud / UTM zone 40N(projected grid) | ±0.1 m |
| 7373 | ONGD14(geographic) | ±0.1 m |
| 9294 | ONGD17(geographic) | ±1.4 m |
The tool covers 17 systems relevant to Oman (national systems plus the WGS84 UTM zones) — the table above lists only the key ones.
FAQ
- Which coordinate system does Oman use?
- Oil-sector sheets and projects sit on PSD93 with UTM zone 39 or 40; older maps use the Fahud datum; modern geodetic work observes on the national ONGD14 or ONGD17 frames.
- What is PSD93?
- The Petroleum Survey Datum 1993 (EPSG:4134) — a refinement of the Fahud datum adopted by Petroleum Development Oman that became the Sultanate’s de-facto project standard, used with UTM zones 39 and 40.
- What is the Fahud datum?
- Oman’s older datum (EPSG:4232), with its origin station at the Fahud oil field. Legacy sheets are drawn on it with UTM (e.g. EPSG:23240 for zone 40); mixing it with PSD93 without a transform shifts points by metres.
- Which UTM zone is Muscat in?
- Muscat (about 58.6°E) sits in UTM zone 40N — EPSG:3440 on PSD93, or EPSG:7375 on ONGD14.
