Handheld data collector
Available from Trimble, TSCe Controller utilizes sight, sound, and
touch to allow surveyors to conduct multiple tasks. The handheld unit
is designed to work in conjunction with the manufacturer’s GPS
survey system and proprietary and third-party total stations. A large
graphic display and memory allow surveyors to view data on a real-time
map. Existing mapping and design data can be viewed as a background
map during a survey. The unit features on-site Internet and e-mail
access capability via external modem or network connection.

GPS mapping system
 Mid-Tech’s Roadway Management System records the placement of up
to six chemicals or chemical mixtures during roadside application.
Operator performing application, vehicle used, date, time, and weather
conditions also are recorded. A built-in chemical calculator function
deduces the amount of chemicals needed to guarantee consistency during
subsequent applications. Using GPS mapping technology and an on-board
mobile computer, georeferenced data can be downloaded and layered with
other information to generate maps at the site to allow correction of
skips before leaving a region.
