RAS2POLY

Description

RAS2POLY converts a raster layer to a polygon layer.

Parameters

Name	Type	Length	Value range
InputRaster: Input raster channel *	Raster port	1 - 1
Output: Output file name *	Vector port	1 -
Smooth vectors	String	0 - 1	YES | NO Default: YES

* Required parameter

Parameter descriptions

InputRaster: Input raster channel

Specifies the input raster channel to be processed.

Output: Output file name

Specifies the name of the file to which the new polygon layer will be saved. This file is created if it does not already exist.

Smooth vectors

Specifies whether or not the vector data will be smoothed (corners rounded).

If the Smooth vectors check box is selected, the vector lines will be smoothed. If the check box is cleared, the created vector lines will follow the pixel edges exactly.

Details

RAS2POLY creates a whole polygon layer based on an input raster. Each contiguous region of equal-valued pixels will be grouped together with polygon boundaries being created around its edge.

If the input is a thematic raster, attributes from that layer are transferred to the output polygon layer.

If you're trying to extract polygons that meet certain criteria from a raster, use EXPOLRAS.
