Benchmark Results
To review and manage performed measurements on a number of known elevations and to accept the results of TS elevation calculation.
Each measurement on a known elevation is a row in the present table with columns showing obtained values:
- Point / Elev - name of the point or the known elevation value;
- Res VA - difference of vertical angle (VA) value from the average of all the VA values;
- Res VD - difference of vertical distance (VD) value from the average of all the SD values;
- HR - height of target (reflector);
- Target Type - method of distance measurement with EDM (Prism, Sheet, Non-Prism or Long Non-Prism);
- PC - prism constant, the parameter of the prism characterizing the difference between the reflection plane and the center of the prism / target offset for non-prism target types;
- HA - horizontal angle measurement value;
- VA - vertical angle measurement value;
- SD - slope distance measurement value;
- Ht Diff - difference between TS elevation calculated from the average of all the measurements and the elevation in this measurement;
- Set - measurement set number and the type of observation in performed measurement.
Use the context menu to manage the list of performed measurements:
- Copy All To Clipboard - copies to clipboard the data of all the measurements in the list.
- Copy Selection To Clipboard - copies to clipboard the data of highlighted measurements.
- Edit - opens the Enter Rod Height dialog to edit the height of the reflector for a highlighted measurement.
- Select All - highlights all the measurements from the list.
- Select All Below - highlights a currently highlighted measurement and all the measurements in the list displayed below.
- Select Multiple - highlights multiple measurements by sequential clicking on data item names.
- Cancel Selection - removes all the highlights in the list.
The standard deviation value for height measurement Sd H is displayed under the table:
- For a single measurement: standard deviation of height measurement (error in height) is calculated considering an instrument error only (residual for a vertical angle and distance measurement).
- For repeated measurements: standard deviation of height measurement (error in height) is calculated considering an instrument error of each measurement and residuals of repeated measurements to the given point.
Click
to save the Benchmark results to a *.txt file.
Use available buttons to manage measurements and to accept the results of TS elevation calculation:
- Add - to measure another known point / elevation in the open the Benchmark: Normal dialog and add it to the table.
- Re-Meas - to delete the highlighted measurement and measure a known point in the open the Benchmark: Normal dialog.
- Remove - to delete the highlighted measurement.
- Accept - to calculate or recalculate the TS elevation based on listed measurements and save the result in accordance with the chosen Update Method (update elevation, rename, or update height of the instrument).
