I'm checking polylines to make sure power pylons were correctly extracted from imagery. Is there a way to find all of the gaps or missed pylons in the database? Currently, I'm manually making a point file from the vertices on the line and checking inconsistencies at a high level. I thought of making a buffer and looking the areas that didn't overlap, but the power pylons are gapped at different distances so it would take forever to run several different buffers for every line in the database. Any other ideas for a more efficient process?
I'm assuming that that you are using Feature Vertices To Points to convert the vertices on your polylines to points. This will mean that the ORIG_FID will enable you to tell which points come from which line.
You should then be able to use Point Distance with a suitable search radius to create a table of each point to its N nearest points.
By using Join Field twice, once for INPUT_FID and then for NEAR_FID, and taking care to "rename" the ORIG_FID from the output of Feature Vertices to Points each time before you join, so that you can distinguish the line each came from, you should be able to identify all points (pylons) from the same line with a distance of more than 60m between them.
