stationLines

Create Station Lines

Creates equally spaced lines along the polylines from the input dataset. The station lines are single segmented polylines perpendicular to the input polylines (at the location of the station).

Inputs:

A polyline feature layer
Distance between stations
Side of the station lines - three options are available
- Both - the middle of the station lines will intersect the original polylines
- Left - station lines will be located on the left side of the polylines
- Right - station lines will be located on the right side of the polylines
Length of the station lines can be specified
- Constant - all the station lines will have the same user specified length
- M Values - the M value of the input polylines (at the location of the station) will be used for length of the station lines. The input polylines must have M values.
- Z Values - the Z value of the input polylines (at the location of the station) will be used for length of the station lines. The input polylines must have Z values.

Outputs:

New Polyline layer with single segmented polylines perpendicular to the input polylines, distributed along the input polylines based on the user selected options.
The attributes of the original polylines are preserved
The following fields are added to the output attribute table
- [ET_ID] - the FID of original polylines.
- [ET_Angle] - the angle of the polyline at the station.
- [ET_Station] - the distance from the start point of the polyline to the station line
- [ET_Length] - the length of the station line

Notes:

The distance is measured in the units of the spatial reference of the input dataset
The output spatial reference is the one of the input polyline dataset

Examples:

Side = "Both", Step = 200 meters, Constant Length = 100 meters

Station Lines

Side = "Right", Step = 100 meters, Constant Length = 100 meters

Station Lines

Side = "Left", Step = 20 meters, Length from Z values

Parameters

Expression	Explanation
Function Name	CreateStationLines
<input dataset>	A String representing the input layer. Must be of Polyline type.
<output dataset>	A String - the full name of the output layer.
<Station Distance>	A Double representing distance between the station lines.
<Side>	Required. A String -This parameter defines on which side of the polyline the station lines will be created: "Both" "Left". "Right"
<Length From>	Required. A String - the source for the length of the station lines: "C", "Constant" - any of the two values can be used "Z", "ZValues" - any of the two values can be used "M", "MValues" - any of the two values can be used
{Length}	A Double representing the length of the station lines if "Constant" length option is selected.

Running the function

ETGWPath used in the table below is the full path to ETGWRun.exe (E.G. "C:\Program Files\ETSpatial Techniques\ETGeo Wizards\ETGWRun.exe")

Language	Syntax
Python	subprocess.call( [ETGWPath, "CreateStationLines", "input dataset", "output dataset", "Station Distance", "Length From", "Length"])
.NET using ETGWRun.exe	StartInfo.FileName = ETGWPath StartInfo.Arguments = "CreateStationLines" "input dataset" "output dataset" "Station Distance" "Length From" "Length"
.NET using ETGWOutX.dll	CreateStationLines(input dataset, output dataset, Station Distance, Length From, Length)
ArcPy	arcpy.CreateStationLines(input dataset, output dataset , "Station Distance", "Length From", "Length")

Notes:

<> - required parameter
{} - optional parameter
See examples for Python , .NET or ArcPy
The argument separator for StartInfo.Arguments is space. If a string might contain a space, you need to double quote it.
