Given a point, a feature or a list of features, this tool calculates all outward flow paths from each selected point or feature. Since the operation is executed on a regular grid, the granularity of the generated flow paths will depend on the given cell size.
Note: when a polygon feature is selected, flow paths will be computed starting from every cell inside the polygon.
Here, one or more flow source features can be selected. The tool will compute the flow paths stemming from all selected features simultaneously. For each selected feature, an independent set of flow paths will be created.
Flow radius
If greater than zero, the outer boundary of the flow source feature(s) will be extended, in all directions, by this distance.
Flow only from current point
If this is checked, instead of calculating flow paths from a list of selected features, the flow paths from the current point under the cursor will be computed.
