Hi,
I'm working on Windows 10, ArcGIS Pro 3.2.2 in a file gdb.
After merging two polygons I get this 'ghost' line between the two previous polygons. In the illustration below I have merged only one polygon.
When I identify or select I get the whole polygon but the ghost lines are still visible:
I've run repair geometry on the feature class but that fixed nothing.
Anyone come across this before? What do those ghost lines mean and how do I get rid of them?
Thanks
Hanlie
Solved! Go to Solution.
The first thing I can think to troubleshoot is to hit "Edit Vertices" and see what you get.
This almost looks like it's being stored as a multi-part polygon that happens to be contiguous.
Quick fix, you can delete the offending vertices if they are there. But the bigger issue is likely in the base dataset: Did you allow multipart polygons? Should you have? Is there some other reproducible bug?

Hi @MErikReedAugusta ,
You're right, I could fix the problem by editing the vertices and deleting the ones that were causing the 'ghost' lines.
I think the original polygons had slight gaps or overlaps and that is what caused the problem. The original was supplied by a client and so I'm not in control of how they created that.
Good lesson for the future: check first for slivers/gaps!
