COGO Options

Postby Michael O'Connor » Fri Feb 28, 2003 10:40 am

I'm examining the Field Genius via the emulator. I cannot find any COGO related functions. Am I missing something?
I had hoped to find an ability to establish a base line or a base curve to measure other observed points (ie. survey monuments) for baseline/offset values etc.
I'm looking for the COGO functions that support analysis of survey data in the field.

FieldGenius Cogo

On my DAP the cogo functions are in a dropdown list located at the northeast corner of the screen.

Michael,

The following information is taken directly from the manual.

This function is found under the Calcs menu.

Traverse/Intersect
Use this function for computing and storing new points by using the following calculations:
1. Input of Angle and Distance
2. Input of Bearing and Distance
3. Bearing-Bearing intersection
4. Bearing-Distance intersection
5. Distance-Bearing intersection
6. Distance-Distance intersection

Command Line Function
Use the FieldGenius Command Line for input. Note that the prompts appear to the left of the input field. Prompts for a point number accept graphic selection of the desired point from the drawing.
Like COGO on MicroSurvey desktop software, this function loops through standard prompts for point numbers, directions and distances to perform the computations based on what is and is not entered. The basic idea is Enter what you know, press Tab or Enter to skip entry of unknowns.

Direct Data Entry
The first prompt is always for an initial point. After entering the first point, each loop always begins with the Angle/Direction and Distance prompts:

1. TRAVX: 1st Pnt [<Point ID>] Enter starting point number or pick it from the drawing.
2. TRAVX: From (1st point entered) [<Direction/Angle>] Enter direction or angle. If an angle is entered, it will be added to the direction to the previous point, to determine the direction to the new point.
See Angle/Direction Input for supported input forms.
3. TRAVX: From (1st point entered) [<Distance>] Enter a distance.
See Distance Input for tips on entering distances.
4. TRAVX: New Pnt [<Point ID>] Enter a point number for the new point. The next available point is displayed as a default, press 'Enter' to use it or enter a different point id. If the point is already defined, a prompt will appear to allow overwriting this point or not.

When a computation is complete, the Cogo Results dialog will be displayed, showing a summary of the calculation.

Press any key to return to the Angle/Direction prompt.
At any time, press Tab to get back to the first prompt.

Press Tab twice to exit the function. Note that this is optional as simply starting another command will exit the Traverse/Intersect function.

Compute Bearing-Bearing Intersection
1. TRAVX: 1st Pnt [<Point ID>] Enter starting point number or pick it from the drawing.
2. TRAVX: From (1st point entered) [<Direction/Angle>] Enter the direction from the 1st point to the intersection point.
3. TRAVX: From (1st point entered) [<Distance>] No Input, press Enter.
4. TRAVX: Other Pnt [<Point ID>] Enter 2nd known point
5. TRAVX: From (2nd point entered) [<Direction/Angle>] Enter the direction from the 2nd point to the intersection point.
6. TRAVX: New Pnt [<Point ID>] Enter a point number for the new point. The next available point is displayed as a default, press 'Enter' to use it or enter a different point id. If the point is already defined, a prompt will appear to allow overwriting this point or not.

When a computation is complete, the Cogo Results dialog will be displayed, showing a summary of the calculation.

Distance-Distance Intersection
1. TRAVX: 1st Pnt [<Point ID>] Enter starting point number or pick it from the drawing.
2. TRAVX: From (1st point entered) [<Direction/Angle>] No Input, press Enter.
3. TRAVX: From (1st point entered) [<Distance>] Enter the distance from the 1st point to the intersection point.
4. TRAVX: Other Pnt [<Point ID>] Enter 2nd known point
5. TRAVX: From (2nd point entered) [<Direction/Angle>] No Input, press Enter
6. TRAVX: From (2nd point entered) [<Distance>] Enter the distance from the 2nd point to the intersection point.
7. TRAVX: New Pnt [<Point ID>] Enter a point number for the new point.

Choose from two Possible Solutions
When there are 2 possible solutions to your calculation, a graphic dialog will appear illustrating an A or B option. Choose A or B to store the point as desired or press Cancel to abort.

Bearing-Distance or Distance-Bearing Solutions are input in the same fashion. Simply skip the input prompt for the unknowns.

I hope this helps.

Michael,

In the desktop emulator the baseline/curve offsets program is located under the Calcs menu. Choose the Station/Offset routine under the Calcs menu and follow the prompts for Beginning point, radius point, if it's a curve, and end point..Remember to use the Tab key and/or the mouse when keying in data to jump between the data fields even when keying in the offset point number use the tab key, if you hit the Enter key it will take you out of the program and back to the main menu..Use the Webdemo project sample, it has lines and curves.
