SetupSurvey Offsets

(This functionality is available with the Survey Live module)

Used to enter survey offset values. The offsets must be entered before the observation to the point that is to be moved by the offsets. The offsets are blanked after each observation.

Note that different commands are available depending on whether Survey Live was last configured for Total Station or GNSS instrument type.

The Survey Offsets page is accessed from the Survey activity.

Point ID: Enter the Point ID for the next point to be created.
Target Height: Enter the target height above the point.
(Only available for Total Station instrument type)
Method: Select the GNSS offset method.
From auxiliary point: The offsets will be applied to the next observed point, with respect to the line from the auxiliary point to the next observed point.
Reference direction: The offsets will be applied to the next observed point, with respect to the bearing entered in the Bearing field.
(Only available for GNSS instrument type; For total station instrument type, the offsets are always applied with respect to the line from the instrument to the next observed point.)
Auxiliary ID: Select the Auxiliary ID. This can be any existing point, or a temporary point at the current location if the Here button is pressed.  The offsets will be applied to the next observed point, with respect to the line from the auxiliary point to the next observed point.
(Only available for GNSS instrument type and only if "Method / From auxiliary point" is selected)
Here Set the Auxiliary ID to a temporary point at the current location.
(Only available for GNSS instrument type and only if "Method / From auxiliary point" is selected)

PowerSearchPowerSearch Initiate Power Search on the total station. This option is only available if the instrument is Power Search capable and will not be available if the configured Target is Reflectorless.
(Only available for Total Station instrument type)
Bearing: Enter a bearing with respect to which the offsets are to be applied when "Method / Reference direction" is selected.
(Only available for GNSS instrument type and only if "Method / Reference direction" is selected)
Distance: Enter a distance to be added to the next observed point. A positive value increases the distance, negative reduces it.
Offset: Enter an offset to be applied to the next observed point. A positive value moves the observed point to the right, negative to the left.
Elevation: Enter an elevation offset to be applied to the next observed point. A positive value moves the observed point up, negative moves the point down.
