Hi all, I have a line geometry (ALine) and a point(Apoint) belonging to the ALine. Apoint have been evaluated from a second line geometry Bline that cross the Aline using the QgsGeometry intersection function as: Apoint =Bline.intersection(Aline)
I need to calculate distance along Aline from the starting point of Aline up to Apoint. In a certain way this problem could be seen as the opposite of function interpolate of QgsGeometry point = geom.interpolate(currentdistance) where it is known the distance from the beginning and it provide the point at specific distance. In my case I have the point but I need the distance. Thanks Pierluigi -- ________________________________________________________________________ Ing.
