Spatial Join points and polygons

GeoOwl33 — Wed, 12 Oct 2022 15:15:14 GMT

Hi, I need some help with setting up a work flow. I am using ArcPro 2.8.2

I have a set of data points that I need to find out which country they fall within. I do have a country polygon shapefile as well to use as the reference. My initial thought is that I would first have to do a spatial join. Would this be a one-to-one or a one-to-many join operation? This part seems straight forward to me that after the spatial join it will create a new feature class of the combined features. The next steps is where I am lost. How can I populate the country field in my original point feature from the joined feature class?

Thank you so much for your help

Did you try spatially joining the polygon to the points?

Hi Dan,

Yes I did run a spatial join Target = the data points Join feature = Country shape file Join operation = one-to-many Match operation = intersect

Now I have a newly created feature class of the joined features. and my question is how do I populate the country field in my original point data feature class ?

Is there not a common ID field between the original and new? which you can use for an attribute join?

Yes there is. However I did find the too called " Join Attributes From Polygon" which did the trick and then I was able to just do a simple field calc.

Now If I were to have a polygon feature that I wanted to know which country it fell within how could I do that. I do have a world countries polygon shapefile to use as a reference
