Buffer Polylines

Go to ToolBox Implementation

Creates buffer polygons from the polylines of the input dataset. The user can specify the side of the polyline (Left, Right or Both) on which the buffer to be created as well as the shape of the buffer at the end of the polylines - Round or Flat. The buffer distance (in the units of the spatial reference of the input dataset) can be entered as a number (equal for all input polylines)or a numeric field. No negative buffer distance is accepted.

Inputs:

Outputs:

Notes :

Examples:

Round buffer both sides (with dissolve option)

Flat buffer both sides

Flat buffer on the left side Round buffer on the right side
Buffer on the left side cannot be created. Round end will be created if a complete flat end cannot be created.

Command line syntax

ET_GPBufferPolylines<input_dataset> <out_feature class> {buffer_distance_field} {buffer_distance} <Both | Left | Right> <Round | Flat> <dissolve_buffers>

Parameters

Expression Explanation
<input_dataset> A Point feature class or feature layer
<out_feature class> A String - the full name of the output feature class (A feature class with the same full name should not exist)
{buffer_distance_field} A String representing the name of a field in the in the attribute table of the input dataset field name.  The field has the values for the buffer distance to be used.
{buffer_distance} A Double representing the buffer distance (in the units of the spatial reference of the input dataset).
<buffer_side> A String representing the side of the polylines on which the buffers will be created. The available options are: Left, Right and Both
<shape_end> Required. A String representing the shape of the buffer at the ends of the polylines. The available options are: 
  • Round - the buffer at the ends of the polyline will have a circular shape.
  • Flat - the buffer at the end of the polyline will be closed with a straight line passing through the start/end point of the polyline
<dissolve_buffers> A Boolean. If True - the boundaries of the intersecting buffers will be dissolved.

Scripting syntax

ET_GPBufferPolylines(input_dataset, out_feature class,buffer_distance_field,buffer_distance, buffer_side, shape_end, dissolve_buffers)
