thermal infrared cameras
Thermal camera systems are derived from military sensors and
can be used for civil applications like heat loss surveys in
built up areas, monitoring of thermal discharges in open water
and other environmental phenomena.
For heat loss surveys in cities the camera is flow at late evening
or early morning times. Over the last few years Aerodata has
built up extensive experience flying the FLIR HS 6000 SC in
an aircraft. The camera can be deployed at various flying altitudes
thus capturing images at for instance 50cm resolution. Also
this camera is equipped with an Applanix position and orientation
system and all of the images are synchronously time-tagged.
Aerodata developed a very efficient way to calibrate, geo-rectify
and mosaic the individual images into a mosaic of the project
areas.
It can be combined with Aerocam-4 projects for efficient and
economic data acquisition.
laser scanners
Aerodata offers LiDAR with the various sensors it has operated
with like Riegl LMS-Q560, Leica ALS 50-II / ALS 60.
These scanners differ in technology, in laser pulse frequency,
swath width and multiple return characteristics.
light mapping sensor
As of 2010 Aerodata offers “Light Mapping” as a service through
its ability to operate with a special high sensitivity camera
system, the Aerocam-4. The system is integrated with GPS/INS
for high accuracy positioning and orientation. This enables
us to produce seamless mosaics of city lighting at night at
resolutions between 15 cm and 50 cm.
Lightmapping is new to the “geo” world and can be used for mapping
light pollution, light distribution, detecting unsafe areas
that are poorly lit, etc.
It can be combined with thermal infrared projects for efficient
and economic data acquisition.
hyperspectral scanner
The AISA Eagle is a fully integrated push-broom system capable
of detecting data in the range of 400 – 970 nm with a spectral
resolution of 2.9 nm. It can acquire any band combination ranging
from a few spectral bands to full hyperspectral data sets of
244 of bands.
Typical ground resolutions vary from 0.5 m up to 5 m. it is
used for environmental mapping and monitoring projects.
position and orientation
systems
At all times the orientation and position
parameters for each image are recorded during the flight.
In the year 2000 Aerodata Surveys was one of the first European
companies buying the Applanix POS/AV 410 GPS/INS system,
mounted on the ZEISS LMK200 camera. Meanwhile multiple POS/AV
510 systems are used with the various digital camera systems.
