PASCO Corporation is one of the world’s largest
suppliers of geographic information and one of
the leaders in implementing the most advanced
surveying and GIS technology in the Far East.
Based in Tokyo, PASCO is heavily involved with
digital data capture for the airborne, marine and
land survey markets for various GIS, engineering
and land development programs in Japan, and
around the world.
The company utilizes a number of Applanix
position and orientation systems (POS LV)
installed on land vehicles equipped with thermal
sensors, digital cameras, and laser scanning
technology. The mobile mapping system, known
as REAL (Road Excellent Automatic Logging), is
designed for sophisticated monitoring of road
surface conditions, infrastructure planning and
maintenance, and transportation network design.
GIS & Asset Management
"PASCO’s REAL system combines precision sensor data with Applanix fully integrated Inertial/ GPS technology to provide the geospatial community with the most accurate data possible."
The POS LV systems are used as the
geopositioning component for the onboard
sensors, providing the position and orientation
information for the digital video and still
cameras, and laser scanning equipment. The POS
LV system’s ability to operate very effectively
in dense urban environments has proven to
be a tremendous advantage. When GPS signal
reception is blocked by tall buildings, the system
will still provide accurate positioning and
orientation information.
Japan boasts approximately 1,152,207km of
roadway, including 6,114km of expressways.
In addition, a high-speed network of limited access
toll roads connects the major cities on
the islands of Honshu, Shikoku and Kyushu, all of
which need ongoing inspection and monitoring
to ensure they remain fully operational.
Generating accurate and detailed data
without interrupting the flow of traffic
is very important, and the REAL system
has been used very successfully on
many of the busy transportation routes
throughout Japan.
The system is capable of collecting multiple data
sets simultaneously while driving at normal traffic
speeds of up to 100kmh. It is able to acquire
three sets of georeferenced road image data in
a single pass of the vehicle: the condition of the
pavement, the location and shape of the road, and
the road asset features.
Used in conjunction with airborne digital
imagery, the data produced is GIS-compatible
and easily utilized by the various
transportation engineering and
planning departments for their
specific requirements.
