Surface Scan
The Surface Scan routine will automatically take a sequence of shots
within a predefined area when used with a robotic total station
running in reflectorless mode. The data collected can then be used
with PC software to create a 3-D raster image of the surface or to
generate a DTM surface, which can be used to compute volumes.
Before starting a scan, you should check the Surface Scan settings.
1. Select Survey > Surface Scan to open the Surface Scan
routine.
2. Tap the button to check your
settings.
a. The Point Description will be
used for each scanned point
that is stored.
b. The Target Depth Range is used
to specify a minimum and
maximum distance range for
points located on the surface to
be scanned. If any shot taken
has a distance that falls outside
the range specified here, that point will be rejected.
(This is useful to automatically reject any points that
do not fall on the surface you want to scan.)
Note: You can select > Remote Control to quickly measure some
distances to determine your Target Depth Range. (EDM Mode must be
set to Track.)
c. If any shot in the surface scan takes longer than the
time specified in the Maximum Time For a Shot field,
that shot will be rejected and the routine will move on
to the next shot.
d. Tap to return to the Surface Scan screen.
