Figure 6-38 Altimeter
The barometric height sensor (altimeter) determines the altitude of the current
scanner position. The altitude determination is based on the measurement of the
atmospheric pressure. The measured altitude is attached to each scan and can be
used for the scan registration in SCENE (see SCENE manual for more
information). If you want SCENE to automatically use the measured altitude for
the scan registration, switch the Use Altimeter button to ON, else switch it to
OFF. This setting 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.
To see the currently measured altitude on this screen, the use of the altimeter has
to be switched ON.
For scan registration it is sufficient to know the difference in altitude of the
various scanner positions. Before starting your scan project, you should pick a
position of your scanning site which you would like to use as the reference for
the altitude measurements. Move the scanner to this reference position, enter any
height you would like to use for this position and reset the altimeter to this
reference height by clicking on the Sync Reference Height button. All further
altimeter measurements will then be done on the basis of this reference height.
If you want comparable height measurements across different projects, you may
sync the altimeter with a real altitude. For this, pick a reference position of your
scanning site where you know the approximate altitude above sea level. You
may get this value from GPS, a topographic map, or from Google Earth.
