70) Road Stationing |
Methodology | |
| Command: | -78.2 |
| Alpha Alias: | -List CLStaPi2 |
| Description: | Prints decreasing centerline and point of intersection stations to two decimal places |
| Data Format: | -78.2,LineID Station From {Radius-Pt} To {[{Radius-Pt} To] .. } ; |
| Problem: | Given a series of centerline points and radius points defining an alignment with an ending station of 28+52.56. Compute and print centerline stationing as shown. |

$ The advantage is that you can change the
