**Search radius**\\

**Ground margin**\\

**Stripe size** and **Space size**\\
Width of the crosswalk stripe and the distance between 2 consequent stripes.

===== Output =====

**Return stripes**: enables returning multi-feature consisting of separate polygons for each crosswalk stripe.\\

**Default length**: stripe length used only for visualization during the measurement.
