Check for identical elevation codes at intersecting streets

Question

I have a large streets dataset. I was wondering if there was a check for verifying if your streets polylines have identical elevation codes in the attribute table. Thinking about it, this would be an iterative check on each segment verifying geometric connection and then looking in the attribute table to verify the two elevation codes. This is an important problem when combining streets datasets across counties. Many street networks break at bridges, where on analyst put an elevation and another didn't. Does anyone know of a data reviewer check that would look at that?

Alguien tiene algun ejemplo de como funciona Different Z at Intersection

@ThomasRickettThanks for sharing additional details on the scenario. The Different Z at Intersection check would support this scenario (albeit using Z-enabled features). Unfortunately, I don't think the Feature on Feature (aka Geometry on Geometry in ArcMap) will work. The check can find polyline boundaries that intersect (spatial relation: DE-9IM (****T****), but comparing the attribute pairs (ToElevation <> FromElevation, FromElevation <> ToElevation) would generate false-positive results.

@JayCary  I don't have Z-values in my street attribute table. For elevations I have codes in my ToElevation and FromElevation fields. 0 is ground level and 1-9 are for elevation. So endpoints have to have the same elevation codes in order to route.

Is there a Data Reviewer check that would check for elevation codes at endpoints of street segments?
