Every land survey in the UAE in 2026 must meet specific technical requirements set by each authority. Dubai Municipality requires WGS84/UTM Zone 40N/EGM2008 for all submissions. Abu Dhabi DMT uses the same horizontal system but with the Abu Dhabi Local Height Datum. Getting this wrong means permit rejections and costly re-surveys.
Dubai Municipality Survey Standards 2026
Dubai Municipality (DM) requires all survey drawings to comply with DM Spatial Data Standards using WGS84 horizontal datum, UTM Zone 40N projection and EGM2008 orthometric heights. Survey drawings must use correct DM layer naming, include a surveyor’s certification stamp and reference DM-registered primary control monuments.
| Requirement | Dubai DM | Abu Dhabi DMT |
|---|---|---|
| Horizontal datum | WGS84 | WGS84 |
| Projection | UTM Zone 40N | UTM Zone 40N |
| Height datum | EGM2008 | Abu Dhabi Local Height Datum |
| Control accuracy | Class B (±10mm) | Class B (±10mm) |
| As-built accuracy | Class C (±25mm) | Class C (±25mm) |
When Land Surveys are Required in UAE 2026
- Building permit applications — topographic and boundary survey required before DM approves permits
- Construction phase — setting out sign-off at foundation, structural frame and completion
- Building completion certificate — as-built survey mandatory for DM BCC issuance
- DLD land registration — boundary survey matching DLD registered coordinates
- Infrastructure handover — road, utility and drainage as-built surveys before authority adoption

DM Survey Accuracy Classes 2026
| Class | Horizontal | Vertical | Use |
|---|---|---|---|
| A | ±5mm | ±5mm | Primary control monuments |
| B | ±10mm | ±10mm | Construction control networks |
| C | ±25mm | ±20mm | Setting out, as-built surveys |
| D | ±50mm | ±50mm | Topographic surveys, mapping |
EGM2008 — Why It Matters in Dubai
GPS receivers measure ellipsoidal heights — heights above the mathematical shape of the Earth. Dubai Municipality requires orthometric heights — the heights water would actually flow to. The difference in Dubai is approximately +22 to +25 metres. Without applying the EGM2008 geoid model, all your survey levels will be 22–25m wrong. Sky TerraEye applies EGM2008 correction as standard on every survey, ensuring correct DM submission.
