Unmanned aircraft
system enables
quick and efficient
airborne mapping
COWI now offers airborne mapping using unmanned aircraft systems (UAS),
which, despite their modest size, provide valuable information on an area,
quickly, easily and at low cost.
Flight permit issued by the
Danish Transport Authority
COWI is the only company with a permit to
carry out commercial mapping using class-1A
UASs (0-1.5 kg) in urban areas and along major
public roads. The permit has been issued by the
Danish Transport Authority.
COWI’s UAS fleet is remote controlled from the ground via a laptop. The aircraft becomes airborne in just ten minutes and provides results that can be
viewed within 24 hours. To ensure optimum surveying conditions, the UAS
cannot operate under winds exceeding 12 m/s. The integrated 16 megapixel
10x15 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.
Mapping with UAS is a great supplement to COWI’s orthophotos and terrain
models produced using normal aircrafts. COWI draws on more than 40
years of experience in production of orthophotos and terrain photos when
processing 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 drone’s camera can capture overview
photos of an area immediately after a flood, or the UAS fly over an operating
gravel pit to assess the scope of materials in stock, or a field before starting land
development.
