Drone Cameras

• multiSPEC 4C - Ultra precise 4-band accuracy

• The multiSPEC 4C provides image data across four highly precise bands - Green, Red, Red-edge and NIR - with no spectral overlap. In addition, its upward-facing irradiance sensor automatically compensates for sunlight variations, resulting in unparalleled reflectance measurement accuracy.

• Technical features

• Resolution 4 sensors of 1.2 Mp

• Ground resolution 10 cm/px (@100m)

• Sensor size 4.8 x 3.6 mm per sensor

• Pixel pitch 3.75 um

• Image format RAW (Tiff)

Flight Process

• UAV is launched ascending to an altitude of 100 -150m once it has reached it’s designated Waypoint it commences taking pictures.

• 45 minutes of flight time

• 36-57km/h (10-16m/s) cruise speed

• Up to 45km/h (12m/s) wind resistance

• Up to 3km radio link

• Covers up to 1.5-10km2

• Image resolution of 3-30cm/pixel (depending on flight altitude)

• Map areas of up to 1,000 ha (2,470 ac) in a single flight.

• These images are used to create maps and elevation models with accuracy of down to 5 cm (1.9 in).

• Images downloaded into Post Flight Terra 3D software

• Point tools, Cloud Compare,

• Images Combined with the Log file of the UAV Flight Path & Survey Ground Control Points

• Photo Mosaic generated with 60% side overlap and 70% laterally.
