Station Store is a pure calculation routine that will create points based on a station and offset from an alignment and is often useful for calculating right-of-way locations, which are typically defined as station and offset.
You must first define the baseline that can defined by one of the following methods:
Note: These methods are virtually identical to that of (and discussed under) Stake Line/Arc
- Define Line: Select two points to define the line.
- Define Alignment: Select a predefined centerline file (.cl file), graphically pick a polyline or enter a sequence of points.
- Define Arc (3 Points): Select three points on the arc.
- Define Arc (PC, PT, Value): Select the start and end points of the arc and enter the radius length.
Once established, the routine will prompt for the station/offset whose coordinate is to be determined.
Main Measurement
Although the Stake Offset command will directly stakeout a particular station and offset, some users prefer to pre-calculate the station and offset and assign a point ID, then field locate by Stake Point. Station Store permits this pre-calculation of points at any station and offset.
- Settings: (gears) Provides a short-cut link to the Job Settings - Stake interface that permits changes to:
- Start/End Sta: Indicates the starting and ending station associated with the selected alignment.
- Station: Specify the station along the selected alignment.
Note: Decimal places on the stationing are set under Job Settings - Format.
- Left/Right Arrow: Quickly navigate to the previous or next interval station.
- Station List: Use this button to quickly select a station of interest.
- Interval: Indicate the Interval along the alignment where stations of interest are found.
- Interval Calculator: Use this button to customize how the interval is determined and used.
More Information
The options of the Interval Calculator are discussed under the Stake Offset section:
Calculate Increment Station dialog - Offset/Skew: Indicate if the offset is a 90° perpendicular offset to the alignment or if an additional skew angle should be applied to the offset.
Note: A 0° skew is perpendicular to the horizontal alignment and a Skew Ah (Left or Right) of 20° would be 20° "ahead" of the 90° offset (Left or Right).
Note: When specifying a Skew option, the expected angular units are the same as those as set under Job Settings - Format.
Note: Skewed pipes can be quickly calculated by selecting the Skew Bk with its offset and then the Skew Ah with its offset.
- Left/Right: Indicate the side of the offset as traveling in increasing station values.
- Z: The default, prorated elevation along the length of the alignment as provided by any vertical components of the alignment definition.
- Override Design: When enabled, indicate the desired value for the elevation of the computed point.
- Additional VOff: Indicate any additional vertical offset distance that should be applied to the Z elevation of the computed point.
- Segment H/V: Displays the type of horizontal and/or vertical segment type of the current Station.
- Description: The description is read-only as the station and offset but can be edited using the Keyboard Input or Points commands, however,
- Description (edit): A user-defined description can be used (often in conjunction with the Store Multiple option) that supersedes the Description generated by the routine.
Note: The standard Code List can be used to set the description of the point and when coupled with a related Feature Code can automate symbol and/or linework as displayed in the Map Screen.
- Store Multiple: When enabled, points will be stored sequentially at the entered Offset from the Starting Station to the Ending Station as entered.
- Pt ID: Indicate the point number that is to be saved.
- Store: Commits the specified point(s) to the current job.
