I have a line feature class that contains roads that were manually edited. Now I want to check if all road crossings have been edited correctly. I want to check that there is no small gap or overlap (<1m) at the road crossings. Dead ends are not errors. Which tool in arcmap could I use to highlight these errors?
To find small overlaps a solution is here, using first TOPOLOGY and second the tool "Feature Vertices to Points": Automatically marking all endpoints as exception in ArcGIS topology?
I am still looking for a soution for small gaps.
Answer
alternative approach :
1) create end points on all lines
2) create buffers of a given size around all points.
3) use spatial join to count the number of lines that are intersected by the buffer: if you have more than one line, this is either a gap or a dangle (and you can screen out the dangles)
