As the altimeter determines the altitude based on the measurement of the
atmospheric pressure, changes in the air pressure caused by changing weather
conditions have an effect on the resulting altitude. To have precise altitude
measurements, you should therefore check the reference altitude from time to
time, at least at the beginning of each project day or if you experience changes in
the weather. To do this, move the scanner to your reference position again and
compare the altitude reading with the reference height. If there is a difference,
sync the altimeter with the reference height again.
GPS
The position information of the scanner‘s position provided by the built-in GPS
sensor is attached to each scan and is automatically used for the scan registration
in SCENE, if the use of the GPS sensor is switched ON.
Use GPS
- Turn the sensor ON or OFF. Unlike the other sensors, GPS data is
only recorded and attached to each scan if this button is switched to ON. The
reason for this differing behavior is to give you the opportunity to prevent GPS
location data from being recorded in your scans, if you do not want to reveal this
information to others. This button affects the current scanning parameters and
has the same function as the equivalent button in the parameters settings.
See
“Setting the Scanning Parameters” on page 41.
After the GPS sensor is switched
ON, it automatically begins searching for GPS satellites. Note that it may take
some minutes to find all the available satellites and to determine a precise
position information. It is recommended to switch the GPS sensor OFF if it is not
needed or if a GPS signal is not available (e.g. if you are scanning indoor).
