Raster to Polygon

Data Description

• The input raster cells can be of any size, but they must belong to a 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 polygons parameter, the resulting vector data will have the following effects.

Steps

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

Raster to Polygon

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 polygons in the output feature class.

• Simplify Polygons (optional): Determines whether the output polygons will be smoothed into simpler shapes or retain the pixel edges of the input raster.

  • Checked: Polygons will be smoothed into simpler shapes with the minimum number of segments, while approximating the original raster pixel edges as closely as possible. This is the default setting.
  • Unchecked: Polygons will retain the exact edges of the input raster pixels. Using this option to convert the feature class back to a raster will produce a raster identical to the original.

• Output Polygon Features: The output feature class containing the converted polygons.

• Add Result 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.
