Hi team,
I am trying to identify in which polygon (in a set of polygons target) each of a list of points (universe) is located at, but my match results keep empty. I am wondering whether I am not handling the geography data right (this is my first time using the Spatial Tools in Alteryx :) )
Any insight on why the match output keeps empty?
Thanks in advance!
Solved! Go to Solution.
Hey @amandalanganke I think you need to check your data here as looks like a quality issue - if we Browse your cluster of polygons, they're in the middle of the Atlantic Ocean:
Whereas your Centroids are all in South America:
So naturally, there'll be no matching here.
Adding onto what @DataNath has said above, it looks like your polygons have reversed lat/long, but I think that's been generated outside this workflow. By reversing the Lat/Long of the centroids, you can match 1796 records, but they're matching in that wrong location (i.e in the ocean).
Super thanks! I have downloaded the polygon dataset from an official government website, but guess it not reliable..
That is already super helpful! Thks a lot
