GPTool

public class StreamToFeature
extends AbstractGPTool

Converts a raster representing a linear network to features representing the linear network. The Stream to Feature tool is contained in the Spatial Analyst Tools tool box.

Software restrictions: none

Usage tips:

• The input stream raster linear network should be represented as values greater than or equal to one on a background of NoData.
• The results of the Flow Accumulation function can be used to create a raster stream network by applying a threshold value to select cells with a high accumulated flow. For example, cells that have more than 100 cells flowing into them are used to define the stream network. Use the Con or Set Null function to create a stream network raster where flow accumulation values of 100 or greater go to one, and the remainder are put to the background (NoData). The resulting stream network can be used in Stream Link and Stream to Feature. An analytical method for determining an appropriate threshold value for stream network delineation is presented in Tarboton et al. (1991).
• There should be contiguous features with the same value, such as the results of the Stream Order or Stream Link function. Stream to Feature should not be used on a raster in which there are few adjacent cells of the same value.
• The arcs of the output shapefile will point downstream.
