Ranking Polygons by content

TerenceAlexander1 — Wed, 04 Mar 2015 10:50:06 GMT

I am looking for a way to rank polygons by their contents. I cannot divulge the exact context but for sake of argument lets say that I have council "district" polygons as one layer and "roads" as another layer. I would like to show what "districts" have the busiest "roads" in them. I have the stats for the "road usage" and the "roads" often cross several "districts". I would also need to do the same for an alternative to "roads" that will be polygon format.

Sorry if this seems confusing! Any help is greatly appreciated.

I believe you can use spatial join tool. This tool will spatially extract the information of road usage to polygon. Then you can perform different analysis on the polygon and the road usage using summary statistics and assign ranks to polygons.

Hope this is helpful

Turns out this only seems to work for points, not lines and polygon layers. Anyone else have any suggestions?

Use an intersect of the council polygons with the roads. The result will be a lines cut by and enriched with the polygon information. Perform your analysis inside that table and join back to the council polygons.

OK, i'll try this and see if it works.

This is turning out to be a lot harder than I first anticipated! Thanks again for the suggestions.
