Edit Conventional Station¶
Use this dialog to edit values related to a station. If the station is reduced and averaged, this is shown in the dialog header.
Where do I find the dialog?¶
Select Properties... from the context menu in the station list for conventional observations.
Note
A conventional station is by definition a half set in Gemini Terrain.
Station¶
The point name of the setup point for a measured half set. Click the button with three dots to the right to move the station to another station point. You can do this by selecting the new point or entering the point designation.
Correction Code¶
The selected correction code specifies which corrections will be applied to the observations.
Instrument¶
Selected instrument.
The instrument specifies, among other things, the standard deviation for direction, vertical angle, and distance. If you change the instrument in the dialog, these values are automatically recalculated. This also applies if you use the Replace function to change the instrument for multiple stations at once. If the station is reduced, you must change the instrument in the station list before calculation.
Instrument Height¶
In meters. If the field is blank, the vertical angle is only used for reduction of slant-measured distances.
Pressure¶
The pressure unit, mmHg or hPa, is derived from the value in the field. The range is 300 ≤ mmHg ≤ 780, 780 < hPa ≤ 1100.
MmHg and mbar have the same zero point. For conversion, you can use: 760 mmHg = 1013.25 mbar.
Temperature¶
In degrees Celsius.
Handling Observations¶
New... Create a new observation in the selected station. You enter a new dialog where you input the values for the new observation.
Edit... Select an observation and click Edit. The dialog for editing the observation opens.
Delete... Select an observation and click Delete to remove the observation from the station.
Move... If you want to move observations from one station to another, select the observation(s) and click Move...
You then enter a dialog with an overview of available stations. Select the relevant station ID and click OK. It is also possible to create a new station in the dialog.
Move Up/Move Down: With this option, you can move observations up or down in the list. This can be used, for example, when the first sight in the first half set must be included as the first sight in all half sets.
Split Set Measurement¶
When importing observations, you can choose to automatically split the set measurement into stations or not. If you import observations without automation, all observations in a setup will end up in the same station in Gemini Terrain.
It may be relevant not to use automation if the automation fails, for example, when the measurement file also contains station setup data. In such cases, you can manually select the observations included in the set measurements and split these into stations using the Split Set Measurement option.
Note
Remember that one station = one half set in Gemini Terrain.
Gemini Terrain analyzes the observations in the same way as during import, but now on a selection of observations. The algorithm tries to recognize the pattern, ABBA, ABAB, AABB, etc., and informs you of the result in a message box.
If you confirm the message, the program creates new stations (at the end of all stations) with newly generated station IDs. The observations from the original station are then deleted. If the original station has no remaining observations after the operation, it will also be deleted.
Tip
Note that Split Set Measurement can also be performed via the list for conventional observations.
