Using QGIS 2.18.16 I am looking at "renaming" or changing the attributes of points to a unique attribute based on the direction of the points.
For example A1, A2, A3, then next row starts over as B1, B2, B3...
I would like to start at the furthermost point SW and gong in a straight line NE to the end until there is no longer points, then start again with the next row to the west.
Any help would be great.
