Before Calculation¶
The list of observations before calculation contains all observations belonging to the project.
Note
If parts of an observation are Excluded or Temporarily modified, this will be indicated by the symbol -- for excluded and * for temporarily modified.
The explanation of the various columns is described below:
| Column | Description |
|---|---|
| StasjonsID | Identification for the station |
| Linjenr. | Designation of the levelling line. A line typically runs between two (known) elevation benchmarks. This field does not need to be unique; several observations (DHs) can be linked to the same levelling line (e.g., in double levelling) |
| Fra Punkt | Point designation for the point from which DH originates |
| Til punkt | Point designation for the point to which DH goes |
| Instrument | The instrument number indicates which instrument parameters the levelling observation is associated with. See Instrument |
| Høydediff. | Levelled elevation difference between Fra punkt and Til punkt |
| Std. H | Standard deviation of measured elevation difference with unit in meters. All standard deviations are transferred directly from the instrument parameters. If a value already exists on the observation, it is not changed. This therefore overrides the instrument's assumed standard deviation. Used for weighting in the calculation |
| Avstand | Levelled distance (in whole meters) between Fra punkt and Til punkt |
