The dialog window Transit traverse allows the calculation of all kinds of traverses and eventually their storage on the disc or loading from the disc.
The dialog window consists of five parts which can be chosen by selecting a bookmark.
This part contains the coordinates of the connective points and the measured set of directions on them. The input is the same as for all the other calculation jobs.
If the initial or terminal points were measured, enter the entire orientation of the set of directions (described in detail in the polar method). If no measuring took place on the point (fixed traverse without orientation, one-side oriented traverse) enter only its coordinates. Proceed in the same way for the terminal point.
According to the entered data on the connection, the type of the traverse is listed for control purposes.
After entering the orientations, enter the measured data one by one. Add or remove items from the list using the buttons (Add) and (Remove).

For the simplicity of entering, both start and end points of the traverse, for all the traverse types, are entered on the measured data list, even if there were no values measured (e.g. the fixed transit traverse without orientation). |
For the measured points, enter the measured direction and the backward distance, the measured direction and the forward distance, and the station number. If the distances are measured in both directions, the program will calculate the average value and put the difference in the report. If measured only in one direction, it doesn't matter if you enter the distance of the point as the forward distance or from the next point as the backward distance.
At the start point, if measured on it, you enter only the forward distance. The program calculates the orientation of the set (i.e. the zero direction bearing) using a separate orientation of set of directions on the start point (see above).
On the end point, if measured there, you enter only the backward direction, similarly to the start point.
In this window section the results are displayed. There is a coordinate list of the result points and the information on the achieved deviations. This section of the window also contains the selection of the adjustment type and the button for the height calculation.
The program allows two types of adjustment:
Standard
Transformation
The program also allows the calculation of the closed traverse, even if this type of traverse is very unsuitable in terms of adjustment. The closed traverse is entered in the same way as fixed bilateral oriented traverse. If the start and end points are identical, it is necessary to enter the orientation of the set of directions for both points. The program indicates the adjusted input of the closed traverse by displaying the Closed traverse type. This traverse type can't be adjusted by transformation for the reason of identity of the end points.
If you are content with the calculated coordinates, you can drag them from the list into any arbitrary window with a coordinate list. In the same way, it is possible to drag a transit traverse into a window with a project. Only a traverse which has already been assigned a file name can be added to a project (i.e. a traverse which has been already stored in a file, or which was loaded from a file).

When dragging, you must point anywhere in the section Results other than the point list. |
This section of the window contains the input line for the traverse name and the buttons for reading and writing the traverse.
Besides manual entry, the program also offers the option to read the measured data for the transit traverse from the field book. If you want to use this option, follow the steps below:
Open the field book in which the transit traverse was measured. If the measurement is stored in more files, merge them by the command Measured data->Attach file or by copying in the clipboard. Open the coordinate list (lists) with the end points.
Activate the measured data list (e.g. by mouse-pointing on any arbitrary item.).
Press the button (Load from the field book) in the dialog window to calculate the transit traverse.
A dialog window with the list of all the stations from the measurement list will display.
If there was a measurement on the start point of the traverse (free traverse, one-side or both sides oriented), it will be shown on this list. Select it with the mouse and press the button (Add).
If there was no measurement on the start point (fixed traverse), type its number in the editing window for the point number and press the button (Add).
If there were more measurements on some of the stations, the number of the station will be listed more times. The individual positions of the instrument are identified by the order number at the end of the point number after the point (e.g. 5001.1, 5001.2, etc.).
The program adds the points on the traverse point list and offers the list of the stations the traverse can pass through. The program will offer as other stations all those stations which were measured from the previous traverse point and from which the previous point was measured as the orientation.
If only one point meets the conditions, the program will automatically add it on the traverse point list. If more points meet the conditions, the program will offer you their list to select.
Enter the entire transit traverse in this way. If there was no measurement on the end point of the traverse (one-side oriented traverse or without orientation), enter the number of the end point in the editing window and add it to the list using the button (Add).
When the entire transit traverse is entered, press the (OK) button. The program will add all the data from the measured data list and from the coordinate list in the dialog window for the transit traverse calculation. Before the calculation, be sure that all the data were entered correctly.
When all the input values are entered, you can initiate the calculation by pressing the button (Calculation). The program will calculate the coordinate of the transit traverse points, display them on the list Results, and inform you of the achieved deviations. If the traverse was adjusted by transformation, you can look at its parameters by pressing the button (Key).
