Spherical scan settings are located in the File\Settings File\Scan Settings
window. Spherical Scan can be setup for either 4 or 5 overlapping scans.
Selecting 4 scans provides a 15 degree overlap between the scans, while selecting
5 scans provides 22.5 degrees overlap between scans. The final scan at -45
degrees is optional. Click the Include final 45 degree scan box to include it. When
performing a scan from a tripod, this final 45 degree scan is pointed sharply at the
seafloor and may not be of interest. Eliminating this final scan decreases the time
necessary to perform a spherical scan.
Total Pan Angle
Both single and spherical scans can both be set to a specific sector size. There
are many situations when scans less than 360 degrees are adequate, speeding up
the scan process significantly. These controls allow you to set the total pan angle
for the upcoming scan.
Scan Speed
Adjusting the scan speed allows the user to sacrifice point cloud density for
faster scan rates. This setting is adjustable between 1 and 10 degrees per
second, with 1 deg/sec providing the highest density point clouds.
Center Scan Angle
By default, the scan is centered about the Home position. If you want the scan
centered at the current pan position, check the “Center Scan(s) at current pan
angle” checkbox.
Note that if the selected Total Pan Angle will hit a pan angle limit (less than -
180, greater than 180), then the start and stop angles will be adjusted so that the
total scan angle is still obtained. That is, if this option is checked when the current
