Gulf Region Coordinate Systems

Coordinate library

Pick the coordinate system you work in from the library. It opens in Coordinate Transformation, where the target system comes from the same library.

GCC Region Overview

The Gulf Cooperation Council region spans multiple UTM zones. Most projects use WGS84 with local UTM projections.

Regional UTM Zones

Zone	EPSG	Coverage
37N	32637	Western and central Saudi Arabia
38N	32638	Eastern Saudi Arabia
39N	32639	Qatar and nearby Gulf
40N	32640	UAE and nearby Gulf
41N	32641	Eastern UAE

Regional Reference Systems

Primary Standard: WGS84 (EPSG:4326)

Most modern projects across the Gulf use WGS84 as the geographic reference, projected to local UTM zones.

Overview

Gulf engineering and GIS projects often cross national and UTM zone boundaries, so CRS selection must be confirmed before merging survey, CAD and GIS files.

National CRS and datum notes

Use WGS84 for web and GPS exchange, and the contract/project CRS for engineering design.
Saudi, UAE and Qatar workflows commonly use UTM zones 37N, 38N, 39N and 40N depending on longitude.
National frames and legacy datums require approved transformation parameters.

UTM zones and EPSG references

Zone	EPSG	Typical use
37N	EPSG:32637	Western and central Saudi Arabia
38N	EPSG:32638	Eastern Saudi Arabia
39N	EPSG:32639	Qatar and nearby Gulf
40N	EPSG:32640	UAE and Oman-side Gulf workflows

Production note

For cross-border Gulf work, split large datasets by CRS zone where needed, document transformations and keep original coordinates in the project archive.

Production guidance

For Gulf regional work, keep a CRS register in the project folder that records source CRS, target CRS, transformation date and exported format for each file conversion.
