Before you buy

Frequently asked questions

Which drones does it fit?

The DJI Matrice 400, on its own single gimbal connector at port E1.

How well is it protected?

IP54 to IEC 60529, with a dry connector and the card cover closed.

What changes compared with the L2?

A laser spot about 1/5 the size and up to 16 returns, for much better vegetation penetration. Dual 100 MP RGB cameras with a 107° horizontal field instead of 73.7°, and a point cloud half as thick.

What accuracy does it deliver?

At 120 m 3 cm vertical and 4 cm horizontal, at 150 m 3.5 and 5 cm, at 300 m 5 and 7.5 cm (RMSE, DJI test with D-RTK 3).

How much area does it cover?

Up to 10 km² per flight and up to 100 km² per day, on a Matrice 400 at 300 m.

What are the dual 100 MP cameras for?

They widen the field to 107°, so one flight collects data for both an orthomosaic and a digital elevation model.

How many returns does it record?

Up to 16 at 100 and 350 kHz, up to 8 at 1,000 kHz and 4 at 2,000 kHz.

Is a DJI Terra licence needed?

No. Processing L3 data in DJI Terra is free, including accuracy optimization (from version 5.1.0).
