Calculating a Traverse (By Hand) with SurvCE
|
In order to do a hand traverse with SurvCE, go to the MAP screen by clicking the icon in the upper right corner labeled MAP. While in the map screen, select the map settings icon to set your Traverse Defaults .
Traverse Steps:
1 To begin, you must key in the command for inverse by typing “I” (Without the quotes) to establish your occupied and backsight points. The command prompt will display the following:
Cmd:Inverse - Tr/Ss/Pick point or point No
2 Key in the backsight point number followed by the [ENTER] key.
3 Key in the occupied point number followed by the [ENTER] key.
4 Key “T” for Traverse or “S” for Sideshot followed by the [ENTER] key.
5 If you keyed in “T” for traverse the command prompt will be waiting for an angle code by displaying the following:
Cmd:Traverse - eXit/I/Ss/Angle-BC(1-7)<7>
If you keyed in “S” for sideshot the command prompt will also be waiting for an angle code by displaying the following:
Cmd:Sideshot - eXit/I/Tr/Angle-BC(1-7)<7>
The code choices you can key in are as follows:
1 - Northeast Bearing
2 - Southeast Bearing
3 - Southwest Bearing
4 - Northwest Bearing
5 - Azimuth
6 - Angle Left
7 - Angle Right
6 Key in the angle code of choice followed by the [ENTER] key
7 Key in the angular value in the dd.mmss format followed by the [ENTER] key.
8 If you selected a vertical prompt under “Traverse Defaults”, then key in the appropriate value followed by the [ENTER] key.
9 Key in the slope distance followed by the [ENTER] key.
10 Key in the point description followed by the [ENTER] key.
11 Press the [ENTER] key to accept the next available point number or key in a new point number followed by the [ENTER] key.
12 If you traversed, then you are now occupying the new point and are back sighting the previous point of occupation. If you sideshot the new point, then you are still at the previous setup and ready to compute the next point.
13 Options at the command prompt when presented with the messages listed in step 5 are as follows:
X - Exit
I - Inverse
S - Sideshot
T - Traverse
Remember that in order to establish new occupied and backsight point information, you must use the “I” (Inverse) command and define the backsight point first and the occupied point second.
