LASER MAPPING
 PROBLEM: A major water utility in southern Connecticut had a need for adding
all of their water valves, blow-offs and fire hydrants to a 100' scale GIS
base map they purchased from a photogrammetric firm. These locations had to
be of comparable accuracy to the new base map, < 1 meter, they had to be
tied into the NAD 83 Connecticut State Plane Coordinate System, they had to
be collected on separate layers, and the project had to be done within
budget and before winter.
SOLUTION: Mapco employed it's Laser Technology reflectorless
Laser Mapping System and Trimble Pro-XR GPS to allow a 1-person crew to
achieve the required accuracies while coming in under budget and on time.
Because of the limitations of GPS to achieve sub-meter accuracies in many
of the areas that needed mapping, i.e. under trees, near buildings etc.,
Mapco’s Laser Mapping System was used to allow GPS to collect data where it
works best, out in the open.
As a pioneer in this technology Mapco
has the ability to send out one person to perform sub-meter mapping on
features that would otherwise be inaccessible to GPS alone. Sensitive areas
can mapped without disturbance. Items on private property can be mapped
from a public right-of-way without involving owners. Heights of objects
including trees, buildings, overpasses, and utility wires can be measured
in a matter of seconds. Tree inventories can be performed in a fraction of
the time while collecting species and DBH attributes. Operator safety is
also increased because the features themselves are not occupied directly,
but are located from a safe distance. Locating items in busy roadways is no
longer the safety concern that it was.

used alone or in combination with GPS can make your project a success.
