{\WM} algorithm does not have a notion of scale, but it does have a notion of
|
||||
distance. Assuming measurement units in projected coordinate system are meters
|
||||
(for example, \titlecite{epsg3857}), conversion is depicted in
|
||||
distance: it accepts a single parameter $D$, the half-circle's diameter.
