[Qgis-user] Vortex coordinates

[G. Allegri]

You can extract the vertexes of your polygon as a new layer. You can do it
with a tool that you can find under the Vector menu and/or Processing QGIS
algorithms, I don't remember exactly and I don't have a PC right  now.

Then you can use the Field Calculator to create two new columns on your
point layer using the $x and $y expressions. I. e. open the attribute
table, toggle on editing, and open the Field Calculator. Set the new field
as "Double" (decimal) and choose a meaningful precision. Write in the
expression $x. This will populate thw new column with the X coordinates of
your points. Do the same for Y.

Then you can save the point layer as CSV, that you can open in a
spreadsheet editor like Excel.
