I want to improve/adjust/comprehend the formula (see below) that was used in my previous question: Transferring flows (connections + values) between polygons for calculating flow values of mobile data respecting the spatial/geographic gist.
where
- absolute value that is conveying
- area of feature 'A' inside a cell 'I'
- area of a cell 'I'
- area of feature 'B' inside a cell 'II'
- area of a cell 'II'
On the image below, there is a transfer of a value 100 from the cell 'I' to cell 'II'.
My question which factors can alternatively be used, besides the $area, in the formula for achieving better results in calculating the new flow value between feature 'A' inside a cell 'I' & feature 'B' inside a cell 'II'?
Moreover, I will be glad if someone can illuminate the non-meaningfulness/meaningfulness of this formula.
Aim: To compare new values from another source with values that are already known.
Besides the $area, I also own
- addresses where inhabitants live
- number of inhabitants per each address
- thematic layers as polygons, e.g. Forest, Green areas, Streets, Buildings, Water etc.
From the above factors, I tried using the ratio of the area without forest, the number of inhabitants, and the number of addresses. I have access to QGIS 2/3, Python, R.
I previously tried asking it as Transferring values between polygons based on point criteria in QGIS? , however, at this moment I suspect that it was too broad and I did not show enough of my own contribution.
