Remote Elevation
If you set your base on a known benchmark, you can begin collecting
data right away. However, if your base station is on a new point, then
you should calculate the elevation of the base and create or update a
vertical site before collecting new data.
You can use the Remote Elevation routine to occupy a vertical
benchmark with the rover. Applying the results of the occupation
will update the base point elevation and create a new one-point
vertical localization without entering the localization routine. The
horizontal localization will remain unchanged.
The following conditions must be met in order to use the Remote
Elevation routine.
•
The base and rover must be set and the rover cannot be in
manual entry mode.
•
Geoid modeling must be selected with a geoid model selected.
•
Mapping plane mode; projection must be set.
•
Ground – TDS Localization mode; horizontal localization
must be set.
•
If the base is autonomous the horizontal localization must be
solved. If not, you can still use the routine as the “Occupy
Vertical Control Point” routine. Updating the
selected vertical control point will not affect the
base height or vertical localization parameters.
1. Open the Survey | Remote Elevation screen.
2. If your benchmark is not in the job file, select the
Add Benchmark checkbox, enter the Elevation , and
specify a new point number in the New Point field.
Note: You cannot enter a new elevation for an existing
point using the Remote Elevation routine.
3. If your benchmark is a point in the job file, use the
button to select the point, or enter the point number
in the
Select Point field.
