Stations Window

The Stations window displays information regarding all the points observed in the network.

Columns in the Stations window

Name

Name of station.

Type

See Table: Station Color Legend for information on station types.

Latitude

Latitude of the station.

Longitude

Longitude of the station.

EllHgt

Ellipsoidal height of the station.

Source

Indicates whether the station coordinates are from the traverse solution or the network adjustment.

#Files

Number of observations periods for that station.

TotalLen

Total observation time made at that station.

A(mm)

Semi-major axis of error ellipse at that station, as defined from the network adjustment.

B(mm)

Semi-minor axis of error ellipse at that station, as defined from the network adjustment.

DH(mm)

Estimated height standard deviation.

Right-click Options in the Stations Window

The following options are available by right-clicking on a station:

View Solution

Displays the solution from traverse computation and network adjustment, if valid.

Add as Control Point

Allows you to define the station as a control point.

Add as Check Point

Allows you to define the station as a check point.

Edit Control / Check Point

Allows for editing of the input coordinates of stations already defined as check or control points.

Toggle between Control / Check Point

Switches status between control point and check point.

Add to Favourites

Adds the station to the Favourites list, using the computed coordinates.

Remove Processing Files

Removes all observation files logged at that station from the project.

Show Observations

Displays all observation periods for that station in the Observations window.

Show Connecting Sessions

Displays all sessions involving that station in the Sessions window.

Expanding the Stations branch in the Data Objects window on the left-hand side of the Data Manager allows for the stations to be displayed individually in the Stations window. Further expanding each station in the Data Objects window displays all observation files in which the station was observed.

Station Color Legend

Color

Description

Cyan

Control point – A reference station with known coordinates

Dark Purple

Check point – Station has known coordinates available, but they will only be used as a check. Comparisons are found in the TRV file. The network adjustment output file (NET) also shows check point residuals.

Light Purple

Tie point – Two or more sessions are connected as remotes to this station via the traverse solution. The TRV file will show traverse ties.

Yellow

Traverse point – No tie information can be computed as there is only one avenue for establishing coordinates for this station.
