Before Calculation¶
The list of observations before calculation contains all observations associated with the project.
Note
If parts of an observation are Omitted or Temporarily changed, this will be indicated by the symbol "--" for omitted and "*" for temporarily changed.
Below are the standard columns. In addition, some columns will appear depending on the control method for rounds selected under analysis parameters.
Explanations for the various columns are described below.
| Column | Description |
|---|---|
| Station ID | ID of the station |
| Rounds info | Contains the information Averaged values if round reduction has been performed |
| Averaged ID | Shows the ID of the averaged station. |
| Station | Name of the station point. |
| Instrument pos. | Instrument position for the observations. This will be instrument position I for averaged values. |
| Target | Name of the target point. |
| Target theme | Theme of the target point. |
| Hor. direction | Horizontal direction of the observation. |
| Vert. angle | Vertical angle of the observation. It does not matter whether the angle is measured in instrument position I or II. If the angle is to be used for height calculation, both instrument height and sight height must be specified. If instrument height and sight height are blank, the vertical angle is only used for reduction of slant distances. |
| Distance | Distance of the observation. Given in meters. The next column indicates whether the distance is considered slant or horizontal. |
| Hor. distance | An X in this column means the distance is horizontal. |
| Instrument | The instrument number indicates which instrument the observation (station) was set up with. See Instrument. |
| Ih | Instrument height in meters. If BLANK => the vertical angle is only used for reduction of slant distances. |
| Sh | Sight height in meters. If BLANK => the vertical angle is only used for reduction of slant distances. |
| Pressure | The pressure unit, mmHg or hPa, is derived from the value entered in the field. Range: 300 <= mmHg <= 780, 780 < hPa <= 1100. |
| Temp. | Temperature in degrees Celsius. |
| Tension | Tension is used for measuring tape. The unit is kg. |
| Correction code | The correction code indicates which corrections should be applied to the observations. Normally, planimetric calculations are performed in the map plane, and all corrections should therefore be applied. Use code 0. If the measurements are already corrected to the map plane, use code 1 and no corrections are applied. |
| Std. dir. | Standard deviation of measured horizontal direction. Unit: gon. The standard deviation is transferred directly from instrument parameters. If a value already exists, it is not changed. |
| Std. vert. angle | Standard deviation of measured zenith distance. Unit: gon. The standard deviation is transferred directly from instrument parameters. If a value already exists, it is not changed. |
| Std. dist. | Standard deviation of measured distance. Unit: meter. The standard deviation is transferred directly from instrument parameters. If a value already exists, it is not changed. |
