Hei Peppe, I have a tool too, which creates lines from points if an attribute is given that can be used for ordering (well.. assuming that you load the data in the correct order you could just create a new attribute and assign numbers in order).
However, that would just create a line from all points, as there needs to be an indicator where the line is finished and a new started. Getting polygons out of lines is simple with the planar graph function - more or less. stefan Giuseppe Aruta wrote: > Hi London, > thanks for your answer.ù > Really I fegure out I can do it using a spreadsheet. > The basic work is to transform, for instance, a line coordinates: 0,0 0,2 > 2,2 2,0 0,0 into a wkt string: Polygon ((0,0 0,2 2,2 2,0 0,0)).
