This 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 - one for the base point and one for the 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 SurvCE stores information about the base point.  Then you can take a second reading, observing only the zenith/vertical angle to the target object point.  Using these two observations, SurvCE 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 difference between the prism and the target object and the elevation of the target object.

Steps to take a remote elevation reading are as follows:

1. Select Remote Elevation from the Surv menu.
2. Confirm your orientation, and re-shoot the backsight as necessary.
3. Press enter to observe base point (see the figure below).  Point the instrument toward the target and press enter.

4. Press enter to shoot target elevation (see the figure below). Sight instrument on the desired point (such as a wire or top of pole or point on a building) and press Enter.

Back in the REM ELEV screen, your angle, zenith, and slope distance are shown along with the remote height and remote elevation. Press S to store this point.

Other right-side options include:

• R: 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.
• S: This button stores the current target offset point to the job file
• B: This re-initializes the Remote Elevation command, allowing the user to define another base point.  The prompting sequence described above will follow.
• Instrument Icon: This takes the user to the Instrument Setup dialog that is standard throughout the program.
