Remote Elevation

The Remote Elevation command allows you to observe a point that cannot be reached vertically, such as a power line, building top, etc. The routine uses two observations:

  1. a measurement to an accessible "base point" location, then
  2. a vertical angle to the target object.

The routine then calculates the target point's elevation.

By placing the prism below or above the desired point, Carlson SurvPC stores information about the base point. Then you can take a second reading, observing only the zenith/vertical angle to the true target point.

Main Measurement

Using these two observations, SurvPC calculates the intersection of the extended zenith/vertical angle with a vertical line from the base point to determine the elevation. Reporting includes the elevation of the target object as well as the elevation difference between the prism and the target object.

Within Remote Elevation are these measurement/configuration tools:

Legacy Icon Graphic Icon Action
Read Read Read: This allows the user to take additional shots above or below the previously defined base point. Pressing the Enter key will also repeat this command.
Store Store Store: Stores the current reading as a point. The functionality of this routine is governed (in part) by the General - Enter Key setting.
Base Base Base Point: The routine returns to the initial Remote Elevation - Base Point dialog so a new base point can be measured.
Configure Configure Launches the Configure interface for the active piece of equipment.
Setup Setup Directs the user to the Total Station Orientation interface.

Note: Also within Remote Elevation are other common controls; most notably the various Map Screen View Controls.

Back in the REM ELEV screen, your angle, zenith, and distance are shown, along with the remote height and remote elevation.

Example

Steps to take a remote elevation reading are as follows:

  1. Launch the command and confirm the instrument orientation.
  2. Press Enter to observe a base point.
  3. Sight the instrument on the desired point (such as a wire or top of pole or point on a building) and press Enter.
