<p>Hi Alexandre,</p>
<p>did you find time have a look at this stuff?</p>
<p>I would be very interested in an "easy" solution with SQL and
virtual layers :)</p>
<p>Cheers,</p>

<div>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. </div>

That can be a great idea.<br>
<br>
In my problem all a have to start is a polygon, not
necessarily<br>
regular, and the directions and spacing of the lines. The
lines in the<br>
grid doesn't have to be orthogonal and almost never NS/EW.<br>
<br>
That seems to be a little cumbersome for an excel
spreadsheet. 🤔🤔<br>
