                <element name="DESCRIPTION" text="This algorithm computes the directional mean of a set of lines in a vector layer. Each segment of the input lines is treated as a vector. Summing up all those vector, a new one showing the directional mean is obtained. This vector is represented as a single-segment line in the resulting vector layer&#10;&#10;The modulus of the resulting vector provides information about the directional variance. Uniform directions will yield longer vectors. &#10;" description="Description" type="0">
