Examples of potential applications

 

  • Bathymetry.

  • 3D mapping.

  • Estimation of tree height for small trees growing in trials.

Range of flight height and captured zone width (m)

Operated within line of sight, observation altitudes often capped at 120 m.

Spectral Range (nm)

c. 500 - 900 nm.

Spatial Resolution (m)

UAV sensors capable of high point densities approaching 600 pts/m2 using sensors like the Minivux.

Benefits

  • Very high spatial resolution.

  • Can adjust the time of imagery capture to the needs.

  • Ability to capture data in remote, unsafe or difficult to access locations, lowering safety risks.

Limitations

  • Need operator to acquire data in the field and battery life can limit survey duration.

  • A heavy lift drone and ground control points are important.

  • Specialised sensors are expensive and need for skilled operators.

  • Limited by visibility constraints and poor weather conditions.
