An integrated digital mapping device contains a personal pen tablet computer
(PC),
GPS receiver, tilt meter (liquid filled or accelerometer-based), compass and laser
range finder integrated into a single housing. The laser range finder is combined
with a visible laser to provide convenient aiming. The device also includes a trigger
to initiate a measurement cycle. In response to activation of a measurement cycle,
the GPS receiver determines the precise location of the measurement device while
the other components provide a measurement of tilt angle (up or down inclination
pitch), azimuth, and distance an object or area of interest. The roll (left or
right sideways tilt) of the tilt meter also provides information when the tablet
is aligned with planar objects. The data from a measurement cycle is converted
into a predetermined data format for use with the conventional digital mapping
software application program operating within the PC.
