Convert Raster To Feature

The Convert Raster To Feature tool does conversion from raster to feature.

Note:

To run this tool, the portal must be configured for raster analysis.

This functionality is currently only supported in Map Viewer Classic (formerly known as Map Viewer). It will be available in a future release of the new Map Viewer. If you do not see this tool in Map Viewer Classic, contact your organization administrator. Your portal may not be configured for raster analysis, or you may not have the privileges required to run the tool.

Examples

A raster depicting land use can be converted to polygon features for further analysis.

Usage notes

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

The parameters for this tool are listed in the following table:

Parameter	Explanation
Choose raster layer to convert	The input raster that will be converted to feature layers.
Choose field	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.
Choose output type	Specifies the output type. Point—The raster will be converted to a point dataset. This is the default. Line—The raster will be converted to a line feature dataset. Polygon—The raster will be converted to a polygon feature dataset.
Simplify lines or polygons	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. Checked—The line or polygon features will be smoothed to produce a more generalized result. This is the default. Unchecked—The line or polygon features will follow the cell boundaries of the raster dataset. This parameter is only supported if the output type is line or polygon.
Create multipart features	Specifies whether the output polygons will consist of single-part or multipart features. Checked—Multipart features will be created based on polygons that have the same value. Unchecked—Individual (single-part) features will be created for each polygon. This is the default. This parameter is only supported if the output type is polygon.
Maximum vertices per polygon feature	The vertex limit used to subdivide a polygon into smaller polygons. If left empty, the output polygons will not be split. This is the default. This parameter is only supported if the output type is polygon.
Result layer name	The name of the layer that will be created in My Content and added to the map. The default name is based on the tool name and the input layer name. If the layer already exists, you will be prompted to provide another name. You can specify the name of a folder in My Content where the result will be saved using the Save result in drop-down box.

Environments

• Output coordinate system—Specifies the coordinate system of the output layer.
• Extent—Specifies the area to be used for analysis.
• Snap Raster—Adjusts the extent of the output so it matches the cell alignment of the specified snap raster layer.
