BATCH FLOW (BatFlo)

Type: Batch application

Forces lines to flow in one direction.

Detailed Description

This batch application can be used to make the elevations of existing lines flow in a single direction, either with increasing elevations or decreasing elevations. This is useful if your project requirements call for a feature to always flow in a consistent direction, such as when collecting streams. Any single point or series of points that do not flow in the required direction will be replaced by interpolated elevations using the point preceding the incorrect point(s) and the point following the incorrect point(s). If a point or series of points falls at the end of a line, then the previous correctly flowing segment will be used to interpolate the new elevations.

The direction of flow can be specified as increasing or decreasing, and the application may be applied to multiple workspaces and multiple layers. A drive file will be written containing all points that were changed.

Layers that are turned off will not be considered even if they are specified.

Example

This illustrates a line before and after running Batch Flow. The red elevations on the original line represent elevations that do not follow the required decreasing elevation flow of the line. The revised line show that the new elevations in blue after running Batch Flow.

Parameters for Batch Flow

Workspaces to consider

Defines the workspaces to consider when running Fix Arcs. Options are Current workspace or All open workspaces.

Layers to search

Defines the layers to search that contain lines in which the arcs are to be re-defined. This parameter may be entered as a number line.

Direction

Specified the direction the lines should be flowing. Either with decreasing elevations or increasing elevations.

Append to drive file

If set to yes, then points are added to the existing Batch Flow drive file. If set to No, then any old points in the Batch Flow drive file will be cleared.
