Raster to Polyline

Data Description

• The input raster can have any valid pixel size greater than 0 and can be any valid integer raster dataset.
• The Field parameter allows you to specify which attribute field of the input raster dataset will become an attribute in the output feature class.
• Depending on whether you check the Simplify Polylines parameter, the resulting vector data will have the following effects.

The output of choosing whether to simplify polylines

Steps

1. Find the Raster to Polyline tool in the toolbox and double-click to open the tool's window.

Raster to Polyline

Parameter Description:

• Input Raster: The input raster dataset; the raster data must be integer type.
• Field: This field assigns the pixel values from the input raster to the polylines in the output feature class.
• Simplify Polylines (optional): Simplifies the polylines by removing minor indentations, protrusions, or insignificant bends while maintaining the overall shape.
  • Checked: The polylines will be simplified to have the least number of segments while preserving the basic shape. This is the default setting.
  • Unchecked: The polylines will not be simplified.
• Output Polyline Features: The output feature class containing the converted polylines.
• Add Results to Project: This option is only applicable if the output feature class is saved to a geodatabase within the current project. When checked, it will automatically create a layer for the result data and add it to the project.
