PASCO
has, since its foundation as
an aerial surveying company
in 1953, always used the most
advanced technology available
at the time to measure events
on the Earth with high quality
and accuracy.We believe it is
essential to always maintain
the most advanced measurement
technology in order to provide
optimal solutions to customers.
With our outstanding technology,
the best approach can be selected
from a wider possible range
to provide a precise high-quality
surveying service.Objects measured
by us include topographic features,
building profiles, road equipment,
large structures including bridges
and dams, outdoor urban spaces,
indoor spaces such as offices,
underground shopping malls and
plants, and even the geography
of ocean and lake beds.
Satellite Program
Spaceborne SAR Sensor: TerraSAR-X
Multiline
digital airborne sensor system:
ADS40
Seamless scanning of
the surface of the Earth with
a 20 cm resolution
 |
The airborne sensor captures images in three directions: forwards, downwards
and backwards in order
to create seamless aerial
imagery with a ground
resolution of 20 cm.
The sensor collects digital
data in the form of strips
of imagery, rather like
a scanner reading the
Earth’s surface.
The imaged data, collected
from the same aerial position
at the same time in the
same environment, can
be effectively used for
3-D modeling or a broad
variety of different applications. |

Large
format digital aerial camera:
UltraCamD
Aerial survey from
560 meters above the ground
with a 5cm resolution
|
Our
digital area sensor acquires
highly accurate aerial
photographic data from
approximately 560 meters
above the ground up to
a 5 cm resolution.
The Centerline
on roads and pedestrian
crossings, electric wires,
and even their shadows
thrown on the ground,
will appear clearly in
the photographs.
The high-resolution
digital area sensor can
provide digital mapping
at a 1:500 scale, which
could not be done with
previous digital sensors.
This also means a significant
reduction in the time
needed to complete any
digital mapping work. |

Airborne
laser surveying system: ALS50
Aerial 3-D survey from
2,000 meters above the ground
with a 15 cm vertical resolution
 |
Our laser surveying directly
acquires 3-D data with
a vertical accuracy to
within 15 cm. This technology
is typically used for
high-accuracy 3-D modeling
of urban areas to reproduce
a vivid image of the real
landscape.
The advantages of this
technology have also been
shown in surveying the
scope of damage after
disasters, such as slope
failure. |
 |
Hyperspectral
sensor: AISA (Eagle & Hawk)
Surveying plant activity
and materials
| Aerial
surveys also identify
a wide variety of materials
on the ground. For example,
our hyperspectral sensors
can measure the amount
of chlorophyll in plants
to determine their level
of activity, something
that is invisible to the
naked eye.
Sensors can
also measure the amount
of protein contained in
rice plants, thus indicating
how ripe the crops are.
From these aerial measurements
of material on the ground,
we are able to offer new
solutions for environmental
or agricultural issues.
We are currently
making a bold attempt
to study reflection characteristics,
which are not yet fully
understood, and will continue
developing new solutions. |

Thermal
sensor: TABI
Measurement of the
Earth’s surface temperature
to within an accuracy of 0.1°C
| We
can measure the Earth’s
surface temperature from
about 1,000 meters above
the ground to within an
accuracy of 0.1°C.
Even dangerous areas which
are normally inaccessible,
such as volcanoes, can
be covered by this technology,
and the temperature distribution
on the ground can be precisely
identified.
Temperature
measurements carried out
from 1,000 meters above
the ground can be done
to within a 3 meter resolution,
and to a 1 meter resolution
if done from 360 meters
up.
This technology
has been shown to advantageous
in monitoring the effects
of industrial waste water,
heat losses in manufacturing
plants, and heat islands,
which are associated with
global warming and other
serious issues. |

Narrow
multibeam sonar exploration
system
Precise ship-borne
3-D measurement of ocean and
lake bed topography
Our marine (ship-borne) multibeam
sonar system can collect strips
of data for underwater topography
covering a width three to four
times the depth of water at
a time.
The data processing has been
greatly compressed to provide
a vertical resolution of 6 mm
and a horizontal resolution
of between 5 to 10 cm. This
very accurate topographic data
can be used effectively in the
management of dams or port facilities,
such as when surveying silting
in dams or the degree of deterioration
of breakwaters.
[Applications]
- Analysis of deterioration/damage
to breakwaters and other port
facilities
- Analysis of the condition
of dredging around dams/ports
or planning for dredging work
- Analysis of existing fish
bank installations or selection
of appropriate sites for fish
banks or seaweed beds
- Analysis of existing submarine
cable installations or selection
of appropriate sites for installing
cables
- Locating objects that have
sunk to the ocean or lake
bed due to an accident or
unauthorized dumping
Ground
based 3D laser scanning system:
Cyrax 2500, Riegl LMS-Z210
Non-contact 3-D surface
profiling
|
This
instrument used for this
type of surveying radiates
laser beams at a target
object and measures the
time required for the
reflected return beams,
thus determining the exact
profile of the object.
An object
100 meters away can be
profiled to an accuracy
of ± 2 to 6 mm.
An object 350 meters away
can be mapped using wide-angle
scanning up to 300°.
The instrument is well-suited
to measure locations which
are not easily accessible,
objects that it is not
easy to gain contact with,
or complex terrains.
It also provides
highly accurate quick
mapping or modeling of
ancient monuments, cultural
properties, and large
building structures. |

Road
surveying system: REAL
Simultaneous survey
of various road conditions
|
Our
onboard road survey system
'REAL' uses the latest
surveying technology to
provide sophisticated
monitoring of road conditions.
REAL is capable
of acquiring three sets
of road image data at
a time in a single pass
of the vehicle: the condition
of the pavement, the location
and shape of the road,
and the road facilities.
This road survey can be
done at normal driving
speeds (up to 100 km/h)
due to its consistent
digital data processing.
REAL allows
us to efficiently collect
a range of accurate information
in a relatively short
time without having to
choose a timeslot for
the survey. |
