Convert Raster To Feature (Raster Analysis)


Converts a raster to a feature dataset as points, lines, or polygons.


Convert Raster To Feature tool


  • This raster analysis portal tool is available when you are signed in to an ArcGIS Enterprise Link to Understanding analysis in ArcGIS Enterprise portal that has an ArcGIS Image Server Link to What is ArcGIS Image Server configured for Raster Analysis Link to Configure and deploy raster analytics. When the tool is invoked, ArcGIS Pro serves as a client and the processing occurs in the servers federated with ArcGIS Enterprise. The portal tool accepts layers from your portal as input and creates output in your portal.

    The input raster layer supports a layer from the portal, a URI or URL to an image service, or the output from the Make Image Server Layer tool. This tool does not support local raster data or layers.

  • Rasters can be converted to point, line, or polygon features.


arcpy.ra.ConvertRasterToFeature(inputRaster, field, outputType, {simplifyLinesOrPolygons}, outputName, {createMultipartFeatures}, {maxVerticesPerFeature})
ParameterExplanationData Type

The input raster layer.

Feature Set

A field that specifies the conversion value.

It can be any integer or text value.

A field containing floating-point values can only be used if the output is to a point dataset.

The default is the Value field, which contains the value in each raster cell.


Specifies the output type.

  • POINTThe raster will be converted to a point dataset. This is the default.
  • LINEThe raster will be converted to a line feature dataset.
  • POLYGONThe raster will be converted to a polygon feature dataset.

Specifies whether lines or polygons will be simplified (smoothed). The smoothing is done in such a way that the line contains a minimum number of segments while remaining as close as possible to the original raster cell edges.

  • SIMPLIFYThe line or polygon features will be smoothed to produce a more generalized result. This is the default.
  • NO_SIMPLIFYThe line or polygon features will not be smoothed and will follow the cell boundaries of the raster dataset.

This parameter is only supported if outputType is LINE or POLYGON.


The output feature class that will contain the converted points, lines, or polygons.


Specifies whether the output polygons will consist of single-part or multipart features.

  • MULTIPLE_OUTER_PARTMultipart features will be created based on polygons that have the same value.
  • SINGLE_OUTER_PARTIndividual (single-part) features will be created for each polygon. This is the default.

This parameter is only supported if outputType is POLYGON.


The vertex limit used to subdivide a polygon into smaller polygons. This parameter produces similar output as that created by the Dice tool in the Data Management toolbox.

If left empty, the output polygons will not be split. This is the default.

This parameter is only supported if outputType is POLYGON.
