Which Tool do you recommended me to use to get the missing points from a layer ?

Hello,

I have a trouble trying to get a few points that I need to export to a new layer. I have this layer that has 739 points and the other layer that has 514. Both of them have the same name howerver, the 514 points is in an extent area and the 739 points is a bit spread outside of the extent area.

Which tools would you recommend me to get grab the points that 514 points does not have them ? There are probably some points that are missing that I need to grab from the 739 points .

Here is an example of what I am showing you ..

I'd suggest using Select by Location, using the layer with fewer points to select the layer with more points.

https://pro.arcgis.com/en/pro-app/3.1/help/mapping/navigation/select-features-by-location.htm

This should give you the points in the more points layer that overlap the fewer points layer.

Then, in the more points layer, open the attribute table and click the button to switch the selection.

This gives you the features in the more points layer that are not in the fewer points layer.

You can export this to its own new feature class, and then append that feature class to the fewer points layer.

As Bob suggests, or Append/Merge straight away and Dissolve to get rid of coincident points https://pro.arcgis.com/en/pro-app/latest/tool-reference/data-management/dissolve.htm

If you merged the two layers you could run Delete Identical to get rid of duplicates.

Thank you. Tried that... Not working don't know why but it looked like one of the layer has some issues...
