In this project, I have three polygons, see the image below
'Polygons_From', includes input attributes, i.g.
$areafor each quadrate (on the image there are two types of them).
'Polygons_To'polygons for which new values
"Value_3_new"need to be defined
'Border'defines an area where the calculation should be done.
My task is to transfer values from
'Polygons_To' based on a certain aspect/ratio. Of course, I can simply achieve it with the
'Union' function as was suggested in this thread.
$area-factor, but perhaps there are better approaches that will lead me to a much more efficient output?
So, I am asking for a recommendation regarding the technique/workflow that can be applied in QGIS 2.18. Shall I consider only
$area or there are some other criteria?
Moreover, I looking forward to finding some papers that may improve my general understanding of the methodology.
