Search radius
The algorithm searches for high intensity points in the space of which the width is indicated by this value around the coordinates indicated by the user.

Ground margin

Stripe size and Space size
Fixed width of the crosswalk stripe and the distance between 2 consequent stripes.

Step 2D, Step angle and max angle
Starting from the first coordinate indicated by the user, the algorithm searches for the exact length of the crosswalk. The Step 2D value indicates the length

Step angle

Max angle

Context radius


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.
