2) Angle Comps |
Methodology Number 1 of 3 | |
| Command: | 2 |
| Alpha Alias: | Locate Angle |
| Description: | Computes points by angle and distance |
| Data Format: | 2 Set From Backsight-Bearing Angle Distance {[Angle Distance]...} ; |
| Problem: | Given point number 20 on a line bearing South 89°30'30" West (backsight bearing), set point numbers 21 and 22. |
| Solution: | 2 21 20 -3 89 30 30 150 10 14 75.25
-279 52 03 67.51 ; |
Data Description
| Command | 2 | Computes point coordinates by angle and horizontal distance or vertical angle and slope distance. Allows you to compute points by vertical angles and slope distances using the 8E8 and 9E9 subcommands. (See Methodologies 1, 2 and 3) |
| Set | 21 | First point number of the coordinates you want to compute. |
| From | 20 | Previously stored point number from which the coordinates are to be set. |
| Backsight
Bearing | -3 89 30 30 | Direction of the line to the backsight point, i.e., away from the From point number. Bearings may be entered using quadrant definition and angle, or by using point definition.
Note: If you choose to use deflection angles, the direction of the Backsight bearing is modified by 180°, i.e., directing the Backsight bearing ahead. |
| Angle | 150 10 14 | Entered as degrees, minutes and seconds. The angle will be turned to the right when you enter the first data item as a positive number. You can turn the angle to the left by entering the first angle data item as a negative number.
Warning!!! Previous versions of iPOGO required each item to be negative in order to turn an angle to the left. If the degrees were negative and the minutes and seconds were positive, the degrees were turned to the left and the minutes and seconds were turned back to the right. This version of iPOGO turns the degrees, minutes and seconds to the left if the degrees are negative and not equal 0. Recommend setting each of the degrees, minutes and seconds data items to negative for left angles. |
| Distance | 75.25 | Horizontal length of the line in feet from the known point to the point which is to be coordinated.
You can also define the distance using a single slope distance and vertical angle or using a series of slope distances and vertical angles. (See Methodologies 2 and 3) To define the total distance with a single slope distance, enter 8E8 followed by the vertical angle, the slope distance, and ;. (See Methodology 2) To define the total distance with more than one vertical angle and slope distance, enter 9E9 followed by a series of vertical angles and slope distances, and 9E9 ; to denote the end of the total distance definition, and end of command. (See Methodology 3) |

67.51 | Repeating feature of this command. All subsequent points will be set from the last point computed and based on the angle and distance specified.
The subsequent point numbers are automatically assigned and ordered as designated by the Set point. If the Set point is entered as a positive number, the subsequent points will be numbered in increasing order. If you enter a negative number, the points that follow will be numbered in decreasing order. Warning!!!
