AIRBORNE MAPPING
COWI now offers airborne mapping using Unmanned Aircraft System (UAS),
which, despite their modest size, provide valuable information on an area,
quickly, easily and at low cost.
COWI’s UAS fleet is remote controlled from the ground via a laptop. The
aircraft become airborne in just ten minutes and provides results that can
be viewed the within 24 hours. To ensure optimum surveying conditions,
the UAS cannot operate under winds exceeding 12 m/s. The integrated 16
megapixel 10 x 15 digital camera produces pin-sharp photos, while a GPS
registers the position of each photo.
The collected data from the UAS can be used to generate a terrain model
for calculating volumes as well as a georeferenced overview map of the area.
Using surveyed control points on the ground, it is possible to achieve an
accuracy of up to 5 cm horizontally and 10 cm vertically.
COWI is one of the first companies
in Denmark having an approval
using UAS for commercial purposes.
Mapping with UAS is a great supplement to COWI’s orthophoto and terrain
model produced using normal aircraft and the benefit is more than 40 years
of experience to be used at production of ortofotos and terrain model from
UAS data.

USEFUL FOR FIELD JOBS
The UAS battery capacity is 30 minutes, making it perfect for field jobs and
mapping of small areas. For instance, the camera can capture overview
photos of an area immediately after a flood, or the UAS can fly over an
operating gravel pit to assess the scope of materials in stock, or a field
before starting land development.
