I am working with TIGER FILES, attempting to use the update (analysis) operation in ArcMap 10.1. The files I'm using are counties, and the incorporated (non-CDP) segment of the places file.
I'm using the counties as the input feature and the places as the update feature. My goal is a layer that has incorporated places, and the remaining (unincorporated) portions of counties.
Given that goal, is the update operation the right approach?
When I do use the update operation, I lose a bunch of the fields from the update features; union gives a more complete result from the perspective of field preservation, but non-contiguous segments of features are not preserved intact.
