LiDAR (Light Detection And Ranging)
GPS
The Global
Positioning System (GPS) is one of the technical marvels of our century. It allows us
to measure our three dimensional location with centimetre accuracy.
INS
Inertial Navigation Systems sense changes in the velocity, pitch, roll and
yaw of an aircraft. INS sees extensive use in the aviation industry and in smart
weapons.
GIS
The Geographic
Information System (GIS) is the software paradigm used to manage GPS positional data.
It allows you to embed all kinds of geographically referenced information in an electronic
map, for example.
LiDAR
Light Detection And Ranging uses the same principle as RADAR. You transmit a beam of light
to a target (the ground) and measure the time it takes for the beam to echo back. You
calculate Range from the
result. |

DigitalWorld's system uses a scanning laser range
finder that sends out thousands of light pulses at varying angles every second.
The principals of DigitalWorld Mapping are world leaders in the development of LiDAR
systems and data acquisition. DigitalWorld's LiDAR System has evolved into one of the most
accurate, reliable and cost effective mapping systems currently available. Our system is
the smallest and lightest of it's kind. DigitalWorld deploys it on a variety of helicopters
and airplanes.
Using LiDAR and digital imaging technology allows us to complete large
area topographic surveys significantly faster and at a reduced cost compared to
traditional survey methods. |
