Group: |
40) Stakeout |
Methodology | |
| Command: | 45 |
| Alpha Alias: | List SSCtrlAngle |
| Description: | Prints stakeout ties as angles and distances from pre-defined traverse points |
| Data Format: | 45 Max-Tie-Length Point# {[Point#] ... } ; |
| Problem: | Given traverse stations 121, 122, 123 (stored in command 41) compute the nearest two ties to points 1, 2, 3 and 4 as shown. Print the clockwise angle and distance to the ties. |
| Solution: | 45 60 1 -4 ; |
Data Description
| Command | 45 | Computes the nearest two ties from traverse stations previously stored with the 41 command to any point number. Prints stakeout ties as clockwise angles and distances.
You must have defined traverse stations using the 41 command before executing this command. For each point number you enter with the 45 command, the two nearest stakeout ties will be printed; however, only one tie will be printed if one of the nearest ties exceeds the indicated maximum tie length. If both ties exceed the maximum, no tie is printed for that point number. The 45 command produces printout only. |
| Max-Tie-Length | 60 | Specifies a length beyond which ties will not be computed. |
| Point# | 1 | Any previously computed point except those stored using the 41 command. |
| {[Point#] ... } | -4 | Repeating feature of this command. Enter additional point numbers for which you want ties computed. If you want to define a series of sequential points, enter the first and last points in the series. The last point number must be preceded by a hyphen.
Example: 1 -50 would define the range for points 1 through 50, inclusive. |
| End Command | ; | All commands end with a semi-colon. |
