23. Coastway – UAV and Payloads
96cm wingspan
- less than 0.7kg take-off weight
- 16MP camera, electronically integrated
and controlled
- Lithium polymer battery
- 50 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
- Linear landing
- Image resolution of 3-30cm/pixel
(depending on flight altitude)
26. Payloads
S110 NIR Standard
Example applications: biomass indication, growth monitoring, crop
discrimination, leaf area indexing.
This customised 12 MP camera is electronically integrated within
the eBee’s autopilot. The S110 NIR acquires image data in the near
infrared (NIR) band, the region where high plant reflectance occurs.
Its exposure parameters can be set manually and its RAW files are
fully supported by the eBee Ag’s software
The multiSPEC 4C is a cutting-edge sensor unit developed by
Airinov’s agronomy specialists and customised for the eBee Ag. It
contains four separate 1.2 megapixel sensors that are electronically
integrated within the eBee’s autopilot. These sensors acquire data
across four highly precise bands, plus each sensor features a global
shutter for sharp, undistorted images.
S110 RGB Optional
Example applications: real colour 2D and 3D visual rendering,
chlorophyll indication, drainage evaluation.
This customised 12 MP camera is electronically integrated within
the eBee’s autopilot. The S110 RGB acquires regular image data
in the visible spectrum, plus its exposure parameters can be set
manually and its RAW files are fully supported by the eBee Ag’s
software.
27. If you do one flight with a RGB camera, and then
another flight with a NIRGB (NearInfrared-
Green-Blue) camera, you can load both datasets
in the software and label them differently (e.g.
RGB and NIRGB) in the initial screen. The
software will do the initial calibration using
geometric information of both datasets, and
your results will be two orthomosaics matching
the band configuration of the original datasets:
one with an RGB bandset and one with NIRGB
bandset. To compute a vegetation index, you
would typically need to combine with a third
party software the first band of the NIRGB
mosaic together with the two last bands of the
RGB mosaic.
28. Development by UAV manufacturer for
Agricultural Mapping
Survey-grade aerial mapping
Collect aerial photography to produce
orthomosaics & 3D models with absolute
accuracy down to 3 cm - without Ground
Control Points. The eBee RTK features a
built-in L1/L2 GNSS receiver. This allows it
to receive correction data from most
leading brands of base station. Its 16 MP
camera can shoot imagery at a resolution of
down to 1.5 cm/pixel. These images can
then be transformed into orthomosaics &
3D models with absolute accuracy of down
to 3 cm / 5 cm – without the need for GCPs.

81. 2. Approaches for sites location and flow
allocation decisions

The goal is to determine an optimal (minimum cost) forest logistic network to
respond future demands
The approach should determine:
Location of facilities (normally from a set of posible sites)
Size and capacity of facilities (storage areas and processing sites)
Volume to harvest in every landing and stand area
Volume of timber to transport from landings to facilities (it gives a first
estimation of road traffic for road planning)
Routes to connect nodes
82. 2. Approaches for sites location and flow
allocation decisions
82
The model should consider inputs like:
Forecast of future demand of timber
Geographic characteristics of the area (Map, distances, slopes, available
areas, sizes, coordinates, …)
Actual roads from forest to mills (forest accessibility). Map, type, …
Amount and quality of available timber
Possible location of mills/biomass areas and distance to the forest
(coordinates, size)
Dimension of the logs needed
Individual costs related to transport, infrastructures costs and others like
clearing meadows or watersides, artificial anchors, locking public roads.

Once the different sites and locations have been selected, and flows between
sites have been determined for each future period,
A Logistics Resource Planning Model will be used to determine the volume to
harvest in every period in every land, processing and transport means, and a
more precise estimation of traffic in every individual sections of road in terms of
number of trip per vehicles type (size, weight) in each period
This traffic estimation will allow to define plans for road maintenance and
construction in the forest area, taking into account the capability of roads to
accept trucks and cranes of different weights and sizes
