Hi Alexandre, did you find time have a look at this stuff?
I would be very interested in an "easy" solution with SQL and virtual layers :) Cheers, Bernd Am 05.05.19 um 10:25 schrieb Alexandre Neto:
That is actually quite easy using a bit of SQL in a virtual layer. After all the west to east and north to south is just a matter of adding a X and a Y fields and order first by X, then by Y. I am not at my computer now, but when I came back I will try to get you a ready to use query. Alex A qui, 2/05/2019, 17:39, Fernando M.

In my problem all a have to start is a polygon, not necessarily regular, and the directions and spacing of the lines. The lines in the grid doesn't have to be orthogonal and almost never NS/EW. That seems to be a little cumbersome for an excel spreadsheet. 🤔🤔 > > Cheers! > > Karl-Magnus Jönsson > > > -----Ursprungligt meddelande----- > Från: Qgis-user [mailto:qgis-user-boun...@lists.osgeo.org <mailto:qgis-user-boun...@lists.osgeo.org>] För > Fernando M.
