I am using the Near 3D tool in Arc 10.4.1 (basic licence) to compare two point shapefiles, both of which have z values. I am interested in the nearest delta x, y and z values between the two sets of points.
When I run the tool, I get correct outputs for delta x and delta y but the delta z column returns only values of 0. The z coordinates for the nearest point is also shown as 0, despite the every point in the shapefile having a z value.
Can anyone suggest why I am not getting the correct delta z values and advise me on how to fix this issue, please?
You set the near_delta option to True ?
You have examined both inputs and calculated a Z value in the table to ensure that they do exist?
Both files are in the same coordinate system?
near_delta is set to True
I've done a computation of the z value in the table and it worked fine.
Both are in the same coordinate system
