extract info from nearest point

IanIrmischer — Mon, 14 Mar 2016 17:59:57 GMT

I am using ArcMap 10.3. I have a point file with 100 features. I would like to extract an attribute (elevation) from the nearest point in the same file.

Any suggestions?

You should be able to use Spatial Join with Closest relationship.

Darren, Thanks. I must be doing something wrong. I try using the spatial

join and "closest" and it just gives joins the attributes of the original

point... Not the nearest. So I get the same elevation value. I found a work

around where I use the near tool and then a join but I thought there might

be a more elegant solution.

Here's an example. I used spatial join with the original points as both the target and join fature classes. The points are labeled by "Id". For example, the highlighted point ("Id" = 2) has an elevation of 5795, and it is closest to point 3 ("Id_1" = 3) which has an elevation of 2896.

This worked very well.
