Coordinate systems in Syria: quick reference
National surveying in Syria rests on a single, well-established datum: Deir ez Zor (EPSG:4227), laid down in the 1920s during the French mandate as part of a unified survey that covered the Levant. The datum takes its name from an origin station near Deir ez Zor in the east, and it still underpins Syria's topographic and cadastral sheets today.
On top of this datum sits the Deir ez Zor / Syria Lambert projection (EPSG:22770), a Lambert Conformal Conic grid that covers the whole of Syria with one coordinate grid instead of splitting the country across UTM zones. A Lambert conic suits a country that extends more east–west than north–south, and it preserves shapes and angles for precise survey work.
The converter below opens on a Damascus sample point. Enter your coordinates to convert between WGS84, the Deir ez Zor datum and the Syria Lambert grid in both directions — with official EPSG parameters and an explicit accuracy badge per system.
| EPSG | System | Accuracy |
|---|---|---|
| 4227 | Deir ez Zor(geographic) | ±0.1 m |
| 22770 | Deir ez Zor / Syria Lambert(projected grid) | ±0.1 m |
The tool covers 3 systems relevant to Syria (national systems plus the WGS84 UTM zones) — the table above lists only the key ones.
FAQ
- Which coordinate system does Syria use?
- Syria uses the Deir ez Zor datum (EPSG:4227) with the Syria Lambert projection (EPSG:22770), a conformal conic grid that covers the whole country in one coordinate frame. Modern work is observed on WGS84 and then converted to the national Lambert grid.
- What is the Syria Lambert projection?
- It is a Lambert Conformal Conic projection on the Deir ez Zor datum (EPSG:22770), designed to cover Syria with a single grid rather than multiple UTM zones. It suits the country's east–west extent and preserves angles for precise work.
- Why is the datum named after Deir ez Zor?
- Because the datum's geodetic origin station lies near the city of Deir ez Zor in eastern Syria. It was established in the 1920s during the French mandate as part of a unified Levant survey.
- Why does GPS disagree with an old Syrian sheet?
- GPS observes on WGS84 while the sheet is drawn on the Deir ez Zor datum with the Lambert grid — the difference can reach tens of metres. The tool applies the published EPSG transformation automatically in both directions.
